What BB to get - s works tarmac - Red AXS

[golty]

Building up a new s works tarmac disc with Sram Red AXS. Wondering what BB to get for it?

My options:

• Standard SRAM DUB BB30 BB (cheap)
  C-Bear BB30 SRAM DUB (expensive)
  Ceramic Speed BB30 SRAM DUB (even more expensive)

Price isn't really an issue, is the ceramic stuff worth the extra?

Thoughts?

First two are regular press-fit type, without any alignment features.
CS one is "screw-together", doesn't require press to fit or remove, have proper alignment (due to screw-together type).
IMHO CS one is better, not because it has fancy ceramic stuff, but shell engineering and tolerances.

Ceramic: will look cool to friends and perform good on a meaningless "spin test" Will get destroyed way sooner than steel if you ride in rain conditions regularly.

Just get a high quality steel bearing BB and save your money.

I'd select the fourth option, Wheelsmfg threaded together:
You get threaded together bb benefit, without ceramic speed's price.

Post Edited: My info was incorrect, Tarmac use bb30 and not pf30

First of all, Tarmac use PF30, not BB30.

Tarmac is 68X42 which is BB30 Ive installed Campy UT cups on all my SWorks (Shiv, Venge, Tarmac SL5/6) and they are the 68X42 model

If the frame can use the bbinfinite one-piece BB and you can get it, it's the best solution for press fit IMO.

Only problem with those one is you need their tool to remove it if you want to.. I have one in my Supersix EVO and it did shut up the creakies, but without their removal tool.. once shes in there.... shes in there!!

Just clicked on their link for the heck of it.. love how they claim there bearing is better than a Campy CULT.. had my laugh for the day...

Their tool seems nothing special to me. There are cheaper ones on ali. I use them to install and remove other BBs. Easy and no shock to the frame. Park tool BBT 90.3 is just an out-of-date tool for removing BB.

Edit: Ah... One-piece BB is much longer, so it needs some improvement to remove BBinfinte. A much longer bolt and a much longer cylinder...

Hambini.

Thanks all will probably just go Ceramic then, seems theres a few discounts on these anyway. I can sell the standard CS BB30 bearings which came with the frame anyway.

Would of got Hambini if he had made them for SRAM DUB, don't think he likes SRAM!

[dannywin42]

I'm sure there is no issue with going from bb30 to DUB though, it's essentially a bb30 bb with a 0.5mm spacer, I.e exactly what he provides for a bb86. The 8605 bearing is 25mm ID shimmed down to 24mm.

It would be worth an email to him at least
