I own a nice C2C Bianchi it is 105 but with cheaper cranks FSA's I saw a great deal for 105's for $100..is the difference in quality worth the effort or do I need to make a major jump to make a diffence? I have no real issue with the cranks but kinda bored with the bike, need wheels but they cost hundreds more, riding Aksiums now.

I doubt you'll notice any difference at all.....do they look nicer - i.e. match your bike better? if so then thats good otherwise probably not worth the effort IMO

I have a FSA Gossamer BB30 crank (everything else is 105), and when I took it into the shop to get my front derailleur adjusted the guy told me that some of teeth on my chainring had bent and that he had easily bent them back with pliers. He explained that the 105 uses a stronger metal than the FSA cranks and also said that that FSA/105 combo could never be adjusted to be as smooth as a 105/105 match. I'm not 100% sure about the second part, but the materials' differences makes sense.

I have a similarly equipped bike and made the change from the FSA cranks to Dura-Ace cranks this past Winter. The accuracy and speed of shifts to the big ring with the DA cranks vs the FSA cranks is definitely noticeable and I would guess you would see similar improvements with the change to 105 cranks. I would definitely make this change for $100.

why are you going into your small ring so often, HTFU

FSA is NOT as qood quality as Shimano. Agree with the inferior steel in FSA. I try to avoid anything from FSA except their 2007 stuff. That year was top notch quality.......then downhill they went.

I had a bianchi via nirone with 105 and gossamer crank. switched to a 105 crank and it was MUCH SMOOTHER. totally worth it if you can afford it.

Shimano has the smoothest front shifting in the business, FSA might be the worst IMHO. I think it's a worthwhile upgrade.

I believe Shimano doesn't make a BB30 crank.

I dont think they do, but they have an adapter you can use

speedwobbles

Possibly, I didn't really look into making the actual change. I'm planning on selling the bike.

I have read that once you introduce the adapter to the equation there is more of a chance that noises (knock, tick, etc) develop. I would just keep the FSA or get something that is BB30 already so that you dont need an adapter.

make the change.
