Spin Doctor Tech Tip: Maintenance on the Fly

Did you miss last night’s In-store Spin Doctor Clinic – or do you not live near one of our shops? Don’t worry, we’ve got you covered with today’s Spin Doctor Tech Tip.
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.
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!
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.
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).
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).
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.
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 works, 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.
