Installing chain rings on road bikes.
I installed new chain rings this evening and feel pretty good with the results. Specifically the big and middle ring on a ten year old shimano crank. Big ring is a new 105 compact ring and the middle is a nice and light ultegra ten speed. consequently its still an 8 speed bike but the rings work fine (thanks sheldon brown) I left the crank on and just removed the rings while the bike was in the workstand. A few things Id note next time around, start with a clean chain! I cleaned mine but it was still a messy job. If you are doing a triple. make sure you don't install the middle ring backwards! I made that mistake. Luckily no blood was drawn but I can see how that might be a hazard. overall brought an old square taper shimano crank back to life. Sanded the crank arm down and used mothers mag polish too. It looks great.
