Ask Performance Answers – 10/4/13

Last week on the Performance Bike Facebook page we asked folks to post questions about bikes or cycling that they wanted an answer to, in a segment we called #AskPerformance. Today we’re going to answer some of your questions below, but if you’ve got other vexing cycling queries, please post them in the comments below and we’ll do our best to find you an answer!

Ron S.: Is it too much to have more than 5 bikes? ;-) #AskPerformance

Ah, the age-old question – the most quoted saying is that the “correct number of bikes to own is ‘n+1′, where ‘n’ is the number of bikes currently owned”. Of course there is an important corollary to this rule, which is ‘s-1′, “where ‘s’ is the number of bikes owned that would result in separation from your significant other”.

Michael S.: #AskPerformance Has the industry established a lifespan projection for carbon fiber frames and components?

There is no standardized lifespan for carbon fiber, as it will depend on how the frame or component is used. That said, there’s no reason carbon fiber can’t last for a very long time – the key is to take care of it properly, only tighten bolts to their recommended torque settings, and inspect it for wear or damage from time to time. We’ve got a great article of tips on our Learning Center: http://learn.performancebike.com/bikes/advice/how-to-guides/bikes-and-frames/taking-good-care-of-your-carbon-bike-frame

scattante_cfr_black_rearDarrell M.: When you shift gears, and the chain moves more than one gear, what is the typical cause and solution?

One main culprit could be a rear derailleur hanger that has come out of alignment – if that is bent (say from setting the bike down on its drive side), then no amount of derailleur adjustment will result in perfect shifting. Another issue could be incorrect routing of the cable to the derailleur bolt – if you’ve changed your cable lately take a look at the instructions for your derailleur to make sure you’ve got that right. If you’ve ruled out a bent hanger and poor cable routing, then you should next take a look at your rear derailleur itself – we’ve got a video in our Learning Center that covers adjusting your rear derailleur: http://learn.performancebike.com/bikes/advice/how-to-guides/bike-parts-and-components/how-to-adjust-a-rear-derailleur

Daisy L.: How many miles before a chain needs to be replaced??

A good rule of thumb is somewhere around 1,500 to 2,000 miles for a road bike, and somewhere around 5-6 months for a mountain bike (assuming that you are riding a fair amount). But these are just general guidelines – to really understand when you should replace your chain you’ll need to measure chain stretch. Chains may be metal, but over time they can actually stretch out quite a bit – we’ve got a handy video that gives you the details of what to look for: http://learn.performancebike.com/bikes/advice/how-to-guides/bike-parts-and-components/how-to-measure-bike-chain-wear

Lidia L.: What is the best way to clean your cogs ? And with what would u clean them with ? Thx ‘s

Cleaning your whole bike is one of the most important things that you can do to prolong the life of your bike and keep it running in tip-top condition (just ask any pro team mechanic). Luckily it’s not that difficult if you follow the how-to on our Learning Center, which covers everything from cleaning your rear cassette to lubing your shifters and brake levers: http://learn.performancebike.com/bikes/advice/how-to-guides/bikes-and-frames/basic-maintenance-how-to-clean-your-bike For the rear cassette, the basic technique is to spray some degreaser onto a cog brush, then wipe down each of the cogs to get the gunk off.

Howard H.: How often should I rotate my tires?

Rotating your tires front to rear is a great idea to increase the longevity of the pair, but keep in mind that most steering control, both off-road and on, comes from the front tire, while more tire wear happens with the drive forces on the rear.  So putting a road tire worn flat or a MTB tire with worn lugs on the front will lessen traction when cornering hard. To prolong the life of your tires, save some money and keep high performance traction, ride your tires until the rear is worn out, move the front tire to the rear, and put a grippy new tire on the front. Need some tips on changing tires? We can help with that: http://learn.performancebike.com/bikes/advice/how-to-guides/tires-tubes-and-wheels/how-to-change-a-road-bike-tire

_131008_dressing_for_coldEnrique L.: Just started riding my bike again like a month ago. but now that the cold weather is upon us what is the best gear for weather of around 40° which is probably the average temp he in the bay area.

The key to riding in changeable fall and winter riding conditions is dressing in layers. You want to keep your core and extremities warm when you get started, but then have the ability to remove and change layers s you get warmed up or if the temperature changes. We call this the 15 minute rule… if after 15 minutes of riding, if you’re still cold, you need more layers or warmer clothing. If you’re uncomfortably hot after 15 minutes, remove layers or wear cooler clothing. We recommend: a medium weight short sleeve base layer, bib shorts, long sleeve jersey, leg warmers, a windproof vest or jacket, windproof full-finger gloves, an ear band or beanie, and toe warmers. You can find all of our cold-weather recommendations here: http://learn.performancebike.com/bikes/advice/how-to-guides/cycling-clothing/dressing-for-the-season-essential-cycling-layering-tips

Maureen K.: A few yrs ago, I switched from riding a hybrid bike to a road bike. On the hybrid, had no problem standing up,out of saddle to get up hills. I’ve had bike fit done on road bike – it fits me sooo much better now, but I am still not comfortable standing to climb up a hill – it’s too scary for some reason! What else should I be doing to get more comfortable standing to pedal up a hill?? Thanks for any suggestions

It is quite a change going from a flat-bar road bike to a drop-bar racing bike – losing the control and leverage you got from keeping your hands in the same position on the handlebars can be disconcerting. But when you stand up to climb on a drop bar road bike, you’ll need to move your hands to your brake hoods to have the most amount of control. Once you practice riding in this position and then smoothly getting up from your saddle, you’ll become more comfortable when you really need it. If you’re looking for other tips on climbing, our Real Advice column has you covered:  http://blog.performancebike.com/2013/07/11/real-advice-an-intro-to-climbing/

Reuben C: Is there a recommended pressure for a tire(as in replacing my 120psi) with the weight of the rider and load in mind. Or are there other factors such as wheel height/length? Sorry im new to riding and it feels like i am running low on psi after bumps or a day of riding (30 miles)

Road tire pressure is definitely critical to a safe and comfortable ride – almost every tire will have a range of recommended tire pressures noted directly on its sidewall. You have flexibility within this range of pressures, so if you feel like the tire is ‘bottoming out’, or compressing so much that it hits the rim, definitely put more air in if it is within the recommendations of the manufacturer. If you are still having issues, you may need to move up to a slightly wider tire (assuming that it fits within your bike’s frame), as this will help give your ride more stability. Or you could install puncture resistant tubes to reduce the chance of pinch flats and slightly increase the load capacity of the bike. If you need help finding the tire inflation range, check out this video: http://learn.performancebike.com/bikes/advice/how-to-guides/tires-tubes-and-wheels/the-right-tire-pressure-for-a-road-bike

Donald H: Help! I tried replacing the cleats on my shoes yesterday. One bolt came out fine, but the other one ended up with the head rounded out to the point the hex wrench has nothing to grip. Any suggestions?

If you are not handy with tools, your best bet is to take the shoe to your local Performance Bicycle to have a mechanic take a look at it. If you want to try yourself (with the caveat that you might damage the sole of your shoe if you aren’t careful) use a Dremel tool with a cut-off wheel to cut a slot in the top of the cleat bolt and used a slotted-head screwdriver to remove the bolt. Be careful not to cut so deep that the bolt head breaks off. It also helps if the shaft of the screwdriver is hex-shaped, so that you can use a wrench to apply more torque to the screwdriver when removing the cleat bolt. And remember to grease your cleat bolts before installing them next time :)

Boone_Road-878Eric Q: #AskPerformance How does one determine how tight/loose to adjust one’s threadless-steerer headset?

Threadless headsets are pretty easy to get set up once you get the hang of it – the key is to tighten the top cap so that you don’t feel any movement fore and aft at the junction of the headset and the head tube, but not so tight that it hinders your turning ability. Then you tighten down the stem pinch bolts to their recommended pressure to lock the stem in place. We’ve got a very clear video that walks you through each step: http://learn.performancebike.com/bikes/advice/how-to-guides/bike-parts-and-components/how-to-adjust-a-bicycle-headset

Greg C: I have my first race coming up next week. Should I shave my legs? Does it make a difference? Will I look like a FRED if I don’t shave?

Another dilemma – shaving your legs is an age-old tradition in the cycling community. Cyclists can give you a litany of rationalizations as to why they shave (such as shaved legs make cleaning up road rash easier and quicker and promote faster healing), but when it comes down to it, shaving your legs is mainly a way to identify yourself as part of the cycling club. Think of it as an initiation into the world of bike racing – you definitely don’t have to shave, but if you don’t, you’d better be fast! We’ve got tips for taking care of your skin here: http://learn.performancebike.com/bikes/advice/riding-tips/general-cycling-tips/basic-guide-skincare-for-cyclists

Chris D: The big question. … I am 6’2 and ride cross country, all mountain and a small amount of DH. 26, 27.5 or a 29er??? It seems so hard to choose a new size with my wide range of riding styles. What is the advantage of a 27.5 vrs a 29er? Also any 2014 recommendations? I hope #askperformance can help! Sincerely a #teamperformance member.

Wow, it sounds like you’re looking for that one bike that can do it all! As a taller guy, you can definitely handle a 29er, which will give you an improved angle of attack to roll over obstacles, and more momentum to smooth out any trail. But the new 27.5″ standard might also be a great option for you – these bikes have a bit more agility than a 29er, but still have a greater ability to roll over obstacles than a classic 26″ bike. We’re pretty excited about the 27.5″ format and think that it might be a great fit for what you want to ride – we’ll have great options soon from GT (the 130mm travel Sensor and 150mm travel Force) as well as Devinci (their all-new 140mm travel Troy). Check out our Learning Center for more info about 29ers: http://learn.performancebike.com/bikes/advice/buyers-guides/bikes-and-frames/basic-guide-to-29er-mountain-bikes and 27.5″ mountain bikes: http://learn.performancebike.com/bikes/advice/buyers-guides/bikes-and-frames/basic-guide-to-275-mountain-bikes

_131003_Boone_Rky_Knob_MTB-340Dawn G.: How do I stop squeaky disc brakes? I’ve cleaned and adjusted them and they still squeak.

There are 2 main things that might be going on if you’ve got everything adjusted right – when you first install new disc brake pads, it’s essential that you go through the ‘break-in’ period for the pads. This will help improve performance and lessen annoying noise – just follow our tips here: http://learn.performancebike.com/bikes/advice/how-to-guides/bike-parts-and-components/breaking-in-your-bike-disc-brakes Of course it could just be the case that the pads have become contaminated with oil or dirt – disc brakes pads a difficult to fully clean once this happens, so often the only alternative is simply to replace the pads all together: http://learn.performancebike.com/bikes/advice/how-to-guides/bike-parts-and-components/how-to-replace-disc-brake-pads

Greg E: I am very interested in getting into cyclocross racing. What is the best way to get started racing for a mature beginner ? I already have a fuji cyclocross bike.

We’re huge fans of cross racing here in the home office – you could even say that we’re obsessed! But really what’s not to love? It’s an all-out effort for 30 minutes to an hour through grass, mud, or sand, with some barriers thrown in just for kicks. Of course this means that some different skills are needed than a regular road ride – you’re already on the right track with a dedicated cyclocross bike, but your next step is to practice cross-specific skills like quick dismounts and remounts, proper technique to carry and run with your bike, and short, hard sprinting efforts to stay in the mix at a race. We’ve got some tips you can follow on our Learning Center, but your best option to learn more is to find a local cyclocross club or training group – cross racers are a friendly bunch, and they’re usually happy to show a beginner the ropes and get him or her just as addicted to cross racing as they are: http://learn.performancebike.com/bikes/advice/riding-tips/road-cycling/cyclocross-basics

Spin Doctor Tech Tip: Maintenance on the Fly

Spin Doctor

In a perfect world bikes would never get flat tires or need periodic repair. But the world is not perfect, and besides it’d get boring if there were no routes, roads or trails that challenged both rider and bike! Instead, dealing with the occasional mid-ride repair is part of the sport. But don’t fret, with a little know-how and the right tools you’ll be ready for just about any problem that comes your way. Here are some tips and tricks to assure you never (well, rarely, anyway) finish a ride by walking your bike back to the garage or local bike shop.

BEFORE YOU RIDE

It’s impossible to prevent all riding mishaps, but a little preparation goes a long way! Before each ride, complete a quick check of your bike and gear: squeeze the brakes and rock the bike back and forth to make sure the brake calipers are tight and that there is no play in the headset; check bolts for tightness (stem and seatpost in particular); look for any frayed brake or shifter cables; check pedals to make sure they are tightly fastened to the crankset (the right pedal tightens clockwise; the left pedal tightens counter-clockwise); lube your chain, then wipe away excess lubricant; check tires for wear, cuts, blisters or lodged glass; pump tires to the manufacturer-recommended pressure (you can find this info on the tire’s sidewall); if you use clipless pedals, check that your cleat bolts are securely fastened. If you notice anything wrong during your check, either fix it yourself or take your bike to your local Performance Bicycle store before your ride!

WHAT TO BRING ON EVERY RIDE

1. Seat Bag or Hydration Pack: To hold the gear below.

2. Tire Levers: Although if possible, install the tire using just your hands (since levers can pinch the tube).

3. Spare Tube: Patching tubes can be tricky.

4. Patch Kit: Your back-up plan.

5. Pump or C02 Inflation System: C02 systems are light and compact, but if you’re planning a long ride, take additional C02 cartridges or a back-up pump as well.

6. Multi-tool: These come in multiple shapes and sizes and configurations – know the bolt sizes on your bike and cleats and find a tool that has those (a tool with 4, 5 and 6mm Allen wrenches, plus flat and Philips head screwdrivers is a good start).

7. Spoke Wrench: These come on many multi-tools.

8. Chain Tool (also on many multi-tools): Broken mountain bike chains are not unusual, and even road chains occasionally snap. With a chain tool you can make a temporary fix to get you home. Don’t forget a replacement chain pin (Shimano) or a chain link connector (i.e. SRAM Power Link).

9. Tire Boot: A large cut in a tire’s sidewall can end your ride. Park Tool’s Tire Boot will adhere to the inside of the tire between the tire and tube to provide a temporary fix to a cut sidewall.

10. Cash: Call this the ultimate multi-tool – you can buy food and drinks, make a phone call if cell service doesn’t work, and even use a folded bill as substitute tire boot!

11. Other Essentials: Cell phone, ID card and any special medical alerts you may have.

FLATS HAPPEN

Whether you ride on the road or trail, you’re bound to get a flat tire once in a while. Make sure you’re comfortable changing a tube by yourself, so you don’t get stranded. Watch our handy How-To video below for a few tips (just remember that if you’re working on a bike with hydraulic disc brakes, never compress the brake levers with the disc removed, as this will push the caliper pistons inward and make it difficult to reinsert the disc).

And now a few IN-A-PINCH PRACTICES:

1. Got a flat and forgot your spare tube? Here are 2 emergency techniques to get you home:

Cut the tube at the puncture then tie it tightly back together. Stretch it into place, re-install the tire and inflate.

No tube, no pump? No worries! Pack your flat tire with as much grass and leaves as you can and pedal gingerly back to your car (this does work, for a little while)!

2. You ignored our suggestion to carry a tire boot and flatted when your tire sidewall got cut. What to do? Place a folded Power Bar wrapper or dollar bill, or a piece of plastic soda bottle between the tube and the cut, then carefully inflate the tire.

3. While shredding the righteous single track at Moab, you taco your front wheel and the tire is now rubbing on the fork. You’re not stuck yet! Remove the wheel from the bike and locate the apex of the bend. With the inflated tire still on the rim, strike the tire at the bend on a hard surface (that shouldn’t be hard to find in Moab). With care you can knock the wheel back into reasonable alignment (at least so it is not rubbing on the fork blades). If you have disc brakes, you are good to go. If you have rim brakes, disconnect them and carefully head back.

4. If you’ve broken a spoke, carefully remove it or, if necessary, wrap it around the nearest intact spoke on the same side of the wheel. Then true the wheel so it doesn’t drag on the frame or brake pads.

5. And finally here are a double speed and a single speed solution:

First, your rear derailleur gets destroyed on a rock. It has come apart and is unusable. Using a chain tool, you can rig your bike up as a single speed. Select a cog in the back that lines up with a ring on the crank. Usually the smaller rings in the front are better. Now cut the chain, drape it around the two rings you have selected, pull it tight and cut it again so the ends just reach. Reconnect it and pedal your new single speed the hipster way home.

Second, you are riding in the mountains and the rear gear cable snaps. The rear derailleur shifts to the highest gear so you and your bike grind to a halt. Are you stuck? Nope, screw in the “H” limit screw on the derailleur while turning the cranks. This will shift the rear derailleur to an easier gear. Continue tightening the screw until you have the easiest gear you can reach. Now pedal your semi-hipster, double-speed way back to the car.
