Hi guys,

does anyone use S-Works Powercranks on an Allez Sprint?
Is there enough room for the left crank arm on the chainstay?

Thanks for the information

I am looking at replacing my BB in my allez sprint and looking for recommendations at which one I should get. I have s-works cranks and stock praxis chainrings at the moment. Am I stuck with press fit bearings as my only option?

I haven't put my hands on the S-Works cranks, but IIRC, those are BB30 spindled cranks, right? If that's the case, I don't *think* there are many other options than PF cartarage bearings, at least I don't know of any. Personally, I'd go with angular contact. You have to preload them a little bit more, Enduro recomends something like 5-7nm, but they should last longer and personally I haven't seen any noticiable difference in drag or friction.

I'll leave it up to you to figure out the other 30%. If you are in any way offended, that's on you.

I have these ones here. Now I have press fit bearings

I replaced my stem and just noticed that when I rotate my handlebars it is not as smooth as it was before. I believe it is the headset and I tq's the expander to spec and only did the top cap to 4-5nm. There is no play in between the frame, step or fork so I know it isn't loose. ideas?

How long have you had the frame? I've developed some minor griding in my bottom headset bearing. So far I've been able to pull the fork, remove the dust seal, clean it out really good and re-pack some grease in there to get it to smooth out a bit for a few months. I've done that probably 3-4 times now. My personal thoughts are that the bottom bearing is a a bit susceptable to water ingress. As for your top cap torque, that's about what I torque my to as well. I ocasionally get a little play, or a *thunk* under heavy breaking, so I usuallay go to about 5nm and then give it an extra 1/8th turn before I tighten down my stem.

I’ve had the bike for a couple years, but it was fine before I swapped the stem. I haven’t really put many miles on the bike under 1k

Yea, that seems pretty low milage for a bearing issue, especially headset. Does it feel like it's binding, or is it that notchy/gravelly, "dirt in the bearings" feel? If it feels like it's binding, maybe too much preload on the top cap? Might be worth it to just pull the fork and spin the bearings with your finger to see how they feel. If you can feel something sticking just moving the bearing with your fingers, there's definately a bigger issue. That's the point that I clean them out and try to get some fresh grease in them.

Unfortunately, the Sprint headset bearings are pressed in, so for most of us it means a trip to the shop if they actually need to be replaced.

Hello, I went with a pressed in module from bbinfinite worked out nice. Swork cranks and a cane creek preload adjuster.

Looking at my sworks cranks on my allez and the sworks power crank on the wifes amira, Looks like the electronics would have plenty of room. The electronic is placed right after the bottom bracket and stay not out by the pedal on the arm.

Did you over tighten your stem cap screw?

I think he did. If he's only put 1000 miles on it in a couple years, then I'd hedge to say he's not too experienced. Especially if he's torquing the headset bolt - I've always done it by feel.

here's a quick link to check for top cap adjustment. You want just enough to preload the bearings and eliminate play, then make sure the stem is straight and tighten the stem clamp bolts (these will have a torque setting, usually 5-6N.m)
