Upgrade crankset 105 > Red?
Moderator: robbosmans
So I have the option to put a used BB30 Red crank of the new model but 10sp on my GT Grade which comes stock with the new Shimano 105 11sp and Praxis BB for PF BB30. Trying to find out if its the right thing to do. The crank has some wear and its 175 instead of 172.5. Its not a show bike but will be ridden to work every day so the wear marks from the shoes is not a big deal.
Any advice is appreciated? Pros/cons?

It will be perfectly functional aside from the thing some people have about mixing components from sram, shimano, campy etc. Yes it will drop some weight as you won't have to use the Praxis converter, however you are not going to notice any weight difference in terms of how it feels. Shifting quality also depends on which gen the sram crank is. The 2012 group onwards has better rings then the old ones.
If you do a search several ppl have successfully 'disguised' their sram crank on an otherwise shimano bike by sanding the decals/clearcoat off of and re-painting it black. I'm guessing if its a work bike then it probably won't matter too much The Grade looks like a pretty cool bike

don't go red... use some CrankSkins to prevent heel rub on cranks
I'd pass. I'm not opposed to the different brands on the bike (if anything, you can always sand and clearcoat). I'd be more concerned about the different crank lengths and price. Keep what you've got and go ride it.

Shimano makes the best equipment. Doesn't pay to upgrade based on weight. Ultegra is slightly higher quality than 105, but if you already have 105 stay with it. The reason why some people go Campy vs Shimano has more to do with preferring the mechanics of how one engages the shifts(use of button etc). Agree that the small weight difference is not a reason to switch.

sram red is as awesome as others despite the rampant fanboism of these forums.. but just the cranks.. not worth it, saves some grams and won't feel much of a diff. The red22 shifting if you were to get that is a good step above 105 (and yes, shimano's dura ace is just as nice)
