that's what i thought, just wanted to make sure a sram bb30 is the same as an fsa bb 30 etc.

shovelhd 04-03-15 07:53 PM

Yes, they are all the same spec.

mike868y 04-03-15 08:03 PM

thanks for the info guys.

will i find a better deal than something like this (Full Warranty SRAM Rival 22 BB30 170mm 50 34 110mm BCD Crankset | eBay my friggin fsa sl-k is messed up again (tightening nut strips because the material is aluminum and super soft). borrowing one for the time being, but need a long term solution.

shovelhd 04-03-15 08:27 PM

Do you need 11 speed?

mike868y 04-03-15 08:33 PM

no, but couldn't find much 10 speed stuff still available.

not my intent to be pedantic on this one, but i think it bears some clarification esp since he seems to be on a budget: all bb30/pf30 cranks have the same spindle diameter (30mm) and are at least 68mm wide. however, there is no standard for how wide they can go. this means that you may need some combination of spacers/wave washers/preload adjuster to get things right.

in the past it was sometimes impossible to get the right spacers for sram bb30 w/o buying the sram bottom bracket...just to get the 10mm spacer. they may be more readily available now. might cost you a few extra bucks.

i can't speak to fSA bb30 cranks as i haven't installed any lately.

mike868y 04-04-15 03:58 AM

I think I'm going to pony up and do what I've wanted to do for a while and upgrade to a shimano crank. This fsa crank has been an utter pos.

wens 04-04-15 05:21 AM

I was pedantic too, just less detailed about it!

shovelhd 04-04-15 05:52 AM

True, it can take some work to get the preload right. Going to a Shimano crank in a BB30 BB is going to require adapters or a conversion BB.

been using tacx tao but they always seem to break after about 8 months for me..

A bit late, but:

I've been using Bontrager Sideswipe RL side-entry cages for years on my MTBs.

Never lost a bottle, on any ride or in any race.

Terrain: Upstate NY, VA, NC, CO, and Lake Tahoe, CA, areas. Racing Pro/Open MTB and the requisite training for that level.

The "never lost a bottle" includes several yard sales where I've taken a spill at Mach Stupid, off road, on east coast rocky trails.

get a praxis adaptor, get a shimano crank - BAM, dunzo for the next pile of years.

About a month ago I got my bb30 rival22 crank on amazon, new, for $60 shipped. (175, 52/36)

Not owning any parts in the above two posts I'd do one of those two, based on what I know about Praxis, Shimano, Rival.

mike868y 04-04-15 02:49 PM

Bike is actually pf30, not bb30. Going to get the wheels manufacturing bearings and a shimano crank.

FWIW: I have recently been using both 10 speed rings on an 11 speed bike (Cassette and chain are 11) and 11 speed rings on a 10 speed bike (10 speed cassette and chain) and both work absolutely fine.

Strongly consider the praxis adapter. The wheels adatpers (if its the delrin cups I'm thinking of) still leave you with the bearing to frame interface issues.

The expanding collet design of the Praxis set up should be more reliable. It is also self-aligning by design, so don't have to worry about alignment of the BB as much.

Mikey, I've got a small bunch of cranks at home for reasons not worth getting into. If you can tell me exactly what you want I can see if I might have something that will work (I'm too lazy to piece it together here). No guarantees as most of my stuff is 172.5, but if you are looking to save a few bucks I might be able to help you.

ips0803 04-07-15 07:55 AM

For the BB30 guys.

I've tried sram, cannondale (which are probably endure re-branded), enduro, and currently Phil Wood bearings. All steel.

I thought I'd be adventurous and got a set of Hawk Racing bearings to try out last fall. After the winter, I decided to put them in the other day to address a slight creak.

Then went in fine, same as all bb30 bearings without much issue. Green Loctite between bearing and shell, RnR SuperWeb between hollowgram spindle and bearings.

Re-assemble the crank and they are *very* stiff/hard to turn. Figure it's just the seal or grease used and they will break in.

Go out for first ride, and the thing clicks and creaks to high hell. Super frustrated I come home and pull the crank. Both bearings have notches and are rough turning.

Completely dumbfounded. They were installed same manner as all the others and I don't understand how they failed so quickly. Going to send my first frustration email to Hawk to see what they say, although I expect them the blame on user install error (not sure how to argue, I understand they can't verify they were installed correctly).

shovelhd 04-07-15 10:51 AM

How did you set the preload?

ips0803 04-07-15 11:24 AM

Hollowgram Si crank (SRM) so non-drive side is non-adjustable shouldered spindle.

Drive Side is bearing shield, 4 plastic spacers (can use up to 5), and wavy washer. Then arm bolt tightened to 40 Nm.

shovelhd 04-07-15 11:28 AM

Have you tried removing one plastic spacer and retorque?

ips0803 04-07-15 12:25 PM

When I reinstalled the other bearings I had, I put them in the same way and no creaking.

The Hawk bearings have very noticeable notches/grinding when turning after the short ride I did on them.

ah ****, i've already got the wheels mfgr on order. fwiw, most of my issues with this bike have been due to the crank, not the actual bb. but, when the wheels mfgr bb wears out, I may switch to a praxis.

caloso 04-15-15 07:20 AM

I have some barely used Reynolds carbon brake pads but they are the Campagnolo shape and my race bike is SRAM/Shimano. Is it possible to alter them to fit Shimano holders? I was thinking I could use a rat tail file on the groove. Anyone tried this?

Get the top-of-the-line Enduro XD-15 BB30 ceramic angular contact kit. Yes, it's $200.

Yes, it's worth it.

You won't regret it.
