Rated 4.5 out of 5 by 13 reviewers.
Rated 4 out of 5 by No-nonsense BB Glad to see these are still readily available to keep my winter mtb running without needing to upgrade the cranks. Very easy to install with the right tools and lifespan is still good compared with the cheap HT2 BB's when used in winter mud. 07 May 2014
Rated 3 out of 5 by Get Rid and ugrade to hollow tech , you will not regret it direct swap for original octalink BB , was a pain in the rear to change , I would recommend spending some cash and upgrading to a hollow tech BB , you will not regret it 22 April 2014
Rated 5 out of 5 by Quailty! Quick delivery, arrived 1st class mail the bottom bracket is well packaged. I will fit this onto my bike soon, Great service and a great product from Shimano :) Thanks, ChainreactionCycles! 19 May 2011
Rated 5 out of 5 by Awesome Runs very smooth. Came with a Specialized Hardrock purchased in 2007 and took three years of use and a few months of weather to bring it down. And because of how cheap and effective it is, I am more than happy to replace it and buy a spare. Great Product :) 04 December 2010
Rated 4 out of 5 by Cheap,easy to fit,very smooth running and weighs 301g. 30 November 2010
Rated 5 out of 5 by Smooth, well made and astonishing value for money! 04 July 2010
Rated 5 out of 5 by Great Deal, Very well made I purchased a total of three withing two months, one of each of my bikes and a spare, My XT one died and replaced it with this and its just a smooth and can't complain about the weight. Made a massive difference to the pre-worn bb and the wallet! 01 July 2010
Rated 4 out of 5 by Make sure you get the right one Unfortunately there are so many different ttypes of BB that I selected the wrong one so it is totally useless. Make sure you know exactly what you need before you order. However, once I got the right one, not from CR though as they were out of stock, fitting it was simple and took five minutes, 18 April 2010

voodoo bokor 29er

Hi there. I have a voodoo bokor 29er and think I need to change the bb . I have measured the spindle (whilst still on the bike with the crank arms off) and I think it's 133 or their about. Would the 127mm do the job? Many thanks in advance. The voodoo bokor is the 2010/11 modal. Matt white if that's any help.

Answer: 
We are not a Voodoo Dealer however research suggests that this bike uses a square taper bottom bracket; spindle length is important for maintaining chainline, it is advisable to re-measure before purchasing a new bearing set.

BB size for Claris chainset

Hi,

I am fitting a new chainset to my 8 speed road bike. I am going to get the Claris chainset and require the appropriate BB. However the octagon bb comes in 3 sizes which don't match the size of the Claris.

You can use the ES51 bracket linked below instead of the ES25 - the Triple ring 2403 crank requires a 121mm spindle length, while the Double ring 2450 requires a 113mm.

Answer: 
Assuming the stock Shimano M430 crankset is still being used; the bottom bracket required is the 68 x 118mm version of the Shimano ES25 (part number - sku117329).

Answers

Answer: 
This bottom bracket will likely fit the frame without any issues, however the spindle length is relative to the crankset which is being used in conjunction with it.

Please provide more information on the intended setup to our Technical Department below -

Answers

Answer: 
If you have retained the original chainset and just removed the additional rings to leave you with a single, you can use the same size of bottom bracket (68x118mm); if you are fitting a new chainset, the bottom bracket spindle length will be dependent upon it.

Not being a Cannondale dealer I am unable to confirm this for you. The best option is to have your local bike shop double check it, or measure it yourself as per the image below.
