How to Put a New Chain on a Fixie

Once used primarily by velodrome racers, fixed-gear bicycles -- or fixies -- are becoming common among riders looking to perfect their pedaling form, those engaged in artistic cycling and cycling sports, and those who simply find them fashionable and fun. Fixies don't have a freewheel for the rear hub, meaning as long as the rear wheel is turning, so are the pedals. This setup, with its high RPM and heavy torque pedaling, puts a lot of stress on the bicycle chain. If you ride a fixie, chances are you'll need to know how to install a new chain.

Instructions

      Remove the old chain from the bicycle using the chain tool. Position the chain within the groove of the chain tool so that one of the chain pins aligns with the slot and the punch. Twist the handle to push the pin out, and separate the chain links.

      Measure the new chain by matching up the number of links on the old one with the new one. Don't match them strictly by length, as the old chain may have stretched. Shorten the new chain by removing excess links with the chain tool, ensuring you have a narrow male link at one end and a wider female link at the other. Do not push the pin all the way out of the link because it's very difficult to get it back in. Push the pin almost all the way out, or just far enough to free the links.

      Loosen the bolts affixing the rear wheel to the frame using the wrench. Slide the wheel forward within the dropouts toward the front of the bike, so that the new chain will have some slack as you install it.

      Place the chain over the front and rear sprockets, then connect the loose ends of the chain by sliding the narrow-link end into the wide-link end. Push the pin back into the chain using the chain tool until it is flush with either side.

      Tighten your chain by sliding the rear wheel within the dropouts away from the front of the bike. When the chain is taut, tighten the bolts.
