Rated 3.4 out of 5 by 61 reviewers.
Rated 2 out of 5 by Cheap but you get what you paid for I bought two on sale, Cheap but you get what you paid for. Both BB's lasted about 400km (not even 6 months) Shimano deore is usually strong and last but these BBs seem to be made from the cheapest materials?? A little dissapointed 26 October 2014
Rated 3 out of 5 by Cheap but short life Good price, easy to fit without Shimano tool (pipe wrench and lots of padding). Longevity not great, around 12mths/5000km of 85:15 on:offroad but not an issue at this price. On my third. 15 October 2014
Rated 2 out of 5 by GT alv 4.0 — более месяца (цела). Norco Sight A 7.2 — неделя (развалилась). Брал эту каретку на хардтейл, как замена квадратам, когда полностью менял трансмиссию. Как потом выяснялось эта каретка была и в приехавших шатунах. На харде всё работает хорошо, за месяц покатушек люфта не обнаружено. Последний раз выезжал на нём в лес после дождя. Проверить работоспособность каретки после этого не успел, т.к. купил подвес и с середины сентября катаю на нём. Где-то через неделю в кареточном узле подвеса появился люфт. Как оказалось дела там совсем плохи: правая чашка в полуразбитом состоянии (пластиковая заглушка съедена и вытащилась вместе с шатуном, подшипник цел), центральная трубка расколота, левую чашку так и не смог выкрутить (решил оставить её, т.к. повреждений на ней нет). В итоге поставил новую правую чашку и разделитель от такой же каретки. В общем как уже говорилось, каретка совершенно не подходит для экстремального катания (хоть мое катание вряд ли можно назвать экстремальным, но каретка убилась). 26 September 2014

Rated 3 out of 5 by цена отражает качество. недорогая и не самая долговечная каретка. Хватило на 3 зимних месяца. Но дёшево. 07 September 2014
Rated 1 out of 5 by It's cheap for a reason Don't expect more than 500 miles off this. It really is rubbish. 30 August 2014
Rated 4 out of 5 by Works as intended The original BB came as standard with my bike and lasted around 800 miles of singletrack, fire roads and xc before I noticed it failing. This replacement was very well priced at CRC and fitting it was pretty straight forward and easy. Although refitting the crank was tricky and needed serious encouragement (tight as). During 1st ride out (Cannock Chase) I could hear creaking coming from it and thought hammering the crank back in had done damage. Pulled everything apart and saw everything was mechanically sound. But not enough grease. Refitted with a load of grease (can't have too much) and all is fine now! Hoping to get another 800 odd miles out if this replacement, but if not at £10 it's well worth it 29 August 2014

Answer: 
Нет. Вам придётся менять и шатуны тоже. К тому же нужно будет торцевать кареточный узел. Эта каретка не имеет своего вала, т.к. рассчитана на систему с интегрированным валом (это когда вал интегрирован в паук, т.е. в левый шатун, на котором закреплены звезды).

Answer: 
The 'Shimano BB51 Deore Bottom Bracket' would use the Hollow 24mm Style of axle found on the likes of the following listed Chainset's;

If you were looking to order a new Chainset the versions listed would also be supplied with a new Bottom Bracket similar to the Shimano BB51 so, you wouldn't need to order one separately.

Answers

Answer: 
While the FSA MegaExo is essentially the same as the Shimano Hollowtech system, they are not listed as cross compatible; FSA Cranks are matched to specific bottom brackets; the SL-K cranks require the BB-8000 series, such as the BB-8681 linked below

Answers

Answer: 
Unfortunately not. The Acera uses a different system. Upgrading to a Deore crank would be a better option, because it comes with the BB with the crank. That would give a much better performance improvement.

Answer: 
No, Acera and Deore use two different bottom bracket types. It would be better to upgrade to a Deore crank as that comes with a bottom bracket. Plus a Deore crank will give much better performance

Answers

Answer: 
This marking bares no significance to the fitment of the bottom bracket cups and likely is a manufacturing process code.

As long as the spacing required is also of 68/73mm for a HollowTech II crankset then this bottom bracket will be fine.
