Rated 3.3 out of 5 by 13 reviewers.
Rated 4 out of 5 by smooth and light a simple easy to fit BB, but has to be slightly adapted to work with a Meta sx 2013 as the flanges foul on the frame... but once these are trimmed down works a treat! havent had any issues with creaking but did grease the frame liberally before fitting 25 August 2014
Rated 1 out of 5 by Calidad insuficiente Debido a la cantidad de polvo y suciedad que se acumula en el pedalier ,pienso que deberían venir los rodamientos sellados.Al no ser así es necesario de vez en cuando desmontar las tapas externas para poder acceder al rodamiento y limpiar y engrasar lo que puedas ya que solo podrás acceder a las caras externas .Pero OJO,estas tapas son de plastico super fino por lo que si no tienes cuidado ,es muy facil romperlas. 21 August 2013
Rated 5 out of 5 by easy to fit very simple to fit you cant go wrong.. bought this to replace my old one that is 3 years old.. but do get the right tools to remove and fit.. 28 June 2013
Rated 5 out of 5 by Отличная каретка. Ход плавный, устанавливается и снимается легко. Использую вместе с системой SLX 660. 08 May 2013
Rated 4 out of 5 by Good! This is a great Bottom Bracket, easy to fit with the right tools. It's been going strong for a few months now. However one problem i've found is that when you want the remove the caps to clean and re-grease, they can easily be broken as they are quite fragile when lifting off with a screwdriver. If you're careful then you'll be ok. Even so, after snapping 2 sections off of one side, and then leaving my bike dirty for a few days, it soon seized right up. But after cleaning and regreasing, it soon freed up again and is super smooth as it was before. 08 June 2012
Rated 2 out of 5 by Not durable Agree with the other post, Shimano can do better. Mine failed after 10 months of use, also on the non-drive side. Not sure about mileage over those 10 months, but my previous BB lasted a good 2+ years. Granted Im 200lbs, but still... 03 June 2012
Rated 4 out of 5 by What else is there? This is what is fitted to my 2011 Giant Trance X3. The original one had done approx 1100 miles before the non drive side gave up (virtually seized). Bought an exact replacement and have now fitted. It was an absolute doddle to do as well, no threads to worry about. However I'm guessing that if I average that sort of mileage I'm going to be changing this every year which is a bit poor I think. I tried to see if there was anything else on the market that would fit but am yet to find anything. Until then I will stick with it! It is super smooth and quiet when fresh though. 31 May 2012
Rated 5 out of 5 by Well after being a proud owner of a Shimano overhead,fast releasing fishing spool during my youth angling years,I was absolutely delighted in learning that I will need a Shimano BB91 press fit bottom bracket for my new 3K carbon fiber fluff magnet. Upon purchasing my bottom bracket from CRC,I showered,shaved and dressed in my favourite,faithful Shimano fishing polo shirt..As this was going to be the catch of the week!...Order complete,job done. I've been smashing the pants off this senorita since Jesus was in his virgin mothers placenta....And I'll tell you what,God himself has nothing on this. As Cher Lloyd would say,"this is for all the haters!"..Change frames and get a BB91 compatible bottom bracket set up!Make sure you order it from CRC!They make the invention of sliced bread seem irrelevant. 06 May 2012

Answer: 
From information available to me it would appear that your frame has a BB95 bottom bracket shell.

This is a Trek specific standard, therefore you will have to source a replacement from your local Trek dealer.

I have just read the above question but I'm confused I have an ex8 and it has a BB91 in it. It has the same failure as everyone else so I was wondering do you have any better replacements compatible with hollowtech cranks?

Answer: 
The only current alternative we have for the Shimano Press Fit brackets are the RaceFace Press-fit cups, which are made to house the same 24mm axle as used on Shimano Hollowtech II

Answer: 
Yes, the BB71/91 brackets run a standard Shimano Hollowtech II crank spindle so this should be fine as a direct replacement.
