Lightest triple groupset with 74bcd?
Posted: Mon Dec 05, 2016 5:38 am
What is my best/lightest option for a 9/10/11 speed triple groupset that still accepts a 24t or 26t granny gear?
My ideal gearing would be 52/38/26 with a 12-27, 13-27, 13-28 etc...
Right now Im running an old 8 speed RSX triple group. I could easily change the gearing if I wanted to, but it would be really nice to have 10 or 11 speed, that way I can get nice, close ratios on the rear cassette while still having a massive range. The RSX is built like a tank. But its super heavy, and I would have to go with something rediculous like a 14-27 cassette if I wanted close ratios. If I stay 8 speed, Ill likely go with some sort of custom 13-27 cassette. But all of that nonsense would seriously hurt my top end speed. Im also looking to avoid going any higher than a 52t chainring as the jump from the 38t to a 54t would be too big for my taste...
Bike: 1999 Trek 2000T wsd.
Bottom Bracket: Shimano BB-LP27, 118mm spindle
Shell Width: 68mm English
What are my best options? Ill stick with the 8 speed if I have to. But If I can upgrade to a lighter 9/10/11 speed group, it can help with ratios and shave alot of weight off the bike. Right now it sits around 21lbs. If I could get it to around 16-18 pounds I would be happy as the bike fits me very nicely and Im not a huge weight weenie. I plan on upgrading the wheelset (with powertap) to something lighter and a crank based power system. But thats for another thread...
