SRAM Alloy GXP Bottom Bracket

Welcome our new Gutter Seal Technology! Gutter drastically improves sealing against the elements while reducing seal drag. We’ve designed a fresh new cup forging for a new high-end look. A new standard in external bearing performance!

Features:

  • Gutter Seal Technology
  • Improved tool engagement
  • Sealed cartridge bearings
  • English or Italian threads
  • Custom steel bearings
  • Tungsten finish
  • GXP: Giga X Pipe External Bottom Bracket Bearing Assembly. While other systems rely on side loading the bearings to eliminate play, which causes premature bearing wear, the GXP system is different. The GXP system captures the left side bearing between the spindle and the left crankarm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long lasting ride.

Rated 3 out of 5 by 30 reviewers.
Rated 1 out of 5 by Poor design After the same problem occurred on 3 GXP bottom brackets I gave up and fitted a Shimano crank set. The plastic sleeve/dustcover on the drive side kept working its way out towards the granny ring allowing play between the spindle and bearing and allowing grit and dirt in. I could bodge it up fitting a spacer between the BB and chain rings. Not good enough. 12 October 2014
Rated 4 out of 5 by Good price, good performance I have replaced my bottom bracket with a like for like replacement the original BB has lasted a year and this has included a winter seriesof 4, 2 hour races and a 12 hour endurance race at Thetford forest which is renound for the destruction of the BB I have no complaints at this price replacing it annualyconsidering the sandy conditions found at thetford forest and the general winter slop ridden in around Essex during the winter. 24 September 2014
Rated 5 out of 5 by Excellent replacement Genuine replacement bottom bracket for my original one after it wore out. 05 September 2014
Rated 1 out of 5 by problems the bearings are not great but bearable ( terrible pun ) however the metal cups seem very poor in strength. when I came to removing it, it didn't help that both cups where seized. I simply couldn't not budge the threads. the seizing may not have anything to do with the bb itself, but my tool (totally legit parktool) cut into the cup with ease. having stripped the cups due to the softness, I used a monkey grip to try and wrench it open. my weight on 2 ft of leverage could not move it. wouldn't recommend 03 September 2014
Rated 4 out of 5 by this product seems ok so far i think its the newer one with improved seals have only done 1/200 miles so far in mud and rain and seems fine so far,but i can service them easily to.so ok for the money. 29 August 2014
Rated 4 out of 5 by Cheep, smooth, doesn't last well in the wet Good cheep middle of the road bottom bracket for most mtb riders. Does not last long in the wet, after a summer of riding just a couple of wet winter rides and it is starting to seize up between rides. Easy to replace but I found the inner plastic sleeve needed to be fitted the opposite way to instructed for a good fit. Would recommend it only because of the price and ease of replacing once stuffed. 26 August 2014
Rated 4 out of 5 by Does what it says on the tin. My last one of these lasted 14 Months, probably 4000km of training and riding hard in all conditions; although the bike is cleaned thoroughly after riding in poor conditions and not used regularly during winter training. I'm happy with this lifespan for a part that's only £20! Moving parts don't last forever, especially if not maintained regularly. Until the bearings collapsed, it ran smoothly without a squeak, tick, creak or groan which is more than I can say for the many other types of Shimano and other branded BB's i've had on this and other bikes. Can't see the point in paying £100+ for a Hope/Ceramic BB as I can't see it lasting 4-5 times as long or rolling significantly better to warrant the cost differential. 20 August 2014
Rated 1 out of 5 by Last only 3 months Drive side bearing gave up after only 3 month. swapped out for a hope will see how it compares. Have a Shimano XT on my other bike and have had 2 years used every weekend rain or shine no problem. If I could get a kit to run Sram GXP on Shimano BB I would 11 July 2014

Answer: 
It'll do fine. That's what I've got, you need to get the spacing right though otherwise it won't torque up. You don't need to tw@ the cranks with a hammer, like SRAM say!

Whyte 901, english 68mm thread?

Hi guys, I need to replace the bottom bracket on my whyte 901 (2011) but I've come into work without measuring the current one. Do you know which thread and size I need? I would have thought it's English thread and 68mm?
Cheers in advance.

Answer: 
Not being a Whyte dealer I can't confirm, but going by the spec on their archive site (http://whyte.bike/2011/bike_page.ph...) it appears to be running a standard GXP (68mm English) but you can double check this by measuring across the shell of your frame (photo below). If you're still not certain, contact your local Whyte dealer or drop us an email with some photos etc http://www.chainreactioncycles.com/...

Answer: 
Hi!

Check out the Hope BB, very good choice, but of course a bit more expensive. Don't forget the GXP converter:

http://www.chainreactioncycles.com/no/en/hope-mtb-stainless-steel-bottom-bracket/rp-prod80494

http://www.chainreactioncycles.com/no/en/hope-bottom-bracket-truvativ-gxp-converter/rp-prod26899

Otherwise, I think some Chris king BB works too for gxp.

Answer: 
It is good, if you torque everything up correctly, you'll have no problems. The other people whining have either tightened it too much or left it too loose, so they get creaking. I've ridden mine in Cham, and had no probs.

Answer: 
The 68/73mm will have the same thread pattern so the cups will fit your 83mm frame ok. The central sleeve will not be long enough, but you may (should) be able to re-use the sleeve from the original bracket that you are replacing.
