Ed BordinI bought this as a drop-in replacement for my worn out BB-51 - it does what it says on the box! I have been enjoying super smooth pedalling since I installed it. One thing to beware - you need a special tool to install this. I happened to have a friend that had the tool already.
Mr BUNTINGGood value for money bottom bracket . Has lasted longer than more expensive makes that I have used previously
Mr AdamsThese are really simple to replace and use and provide good mileage. I have killed a couple off with liberal use of degreasers though so not sure they're entirely sealed. That said, they're so cheap they're practically disposable. They're much stiffer and much lighter than all the internal bearing sets that I've got so I sticking with it.
Mr MurrellGot this to replace the original XT item that came on the bike two years ago. The first thing to note is that externally they look almost identical - the centre tube even had the same part number. I figure if this one lasts a year I'm no worse off than if I'd got the XT one at twice the price - so we'll see. In terms of value for money, I can't see how this could be beaten.
AlanRReally fast delivery as usual, bottom bracket seems to be pretty good too. Maybe not as light as some but still lasts ages
Mr PattersonGreat bottom bracket, very cheap but just as good as the higher up the range bottom brackets. My last one lasted over two years.
Herman GelmetA great replacement for a previous BB51 that had suffered after several years use and very salty roads last winter. Usual quick delivery from Merlin, and naturally the best price.
Mr GiffordBrilliant. Running this on my singlespeed charge duster 11 with XT cranks. Does the job for half the price.
Neil PDoes the job it's intended to - replaced one of the original HTII bottom brackets, and can't see much difference in function between this and the more expensive model. As with all these outboard bottom brackets, having your frame faced to ensure the cups are sitting parallel is crucial for longevity.
Mr SHERIDANSuper fast delivery from Merlin as usual. Bought the BB51 as the BB70 was out of stock. Doesn't seem any different upon inspection and is just as smooth once fitted. My BB71 lasted about a year so too early to tell if this one is as robust. Cannot fault Merlin though as a shop. Have bought from them for 20 years and will continue to do so.
Mr SimeonsThe design of this bottom bracket means that removal and re-fitting is made easier. However, removal, in my experience requires a great deal of force and threads have corroded with long exposure/contact to the internal frame of the bike. With appropriate cleaning of threads and copper slip applied to them, the new bracket will go in very smoothly and easily. Long lasting, light and competitavely priced. Just make sure the frame is faced and finished correctly (this will be a specialist job and cost extra!)
Mr RootesI got this bb to go with a XT crank set and its spot on its early days yet but seems to be performing just as well as the XT bb. For that price can not go wrong.
Mr gregoryGreat value bottom bracket from Shimano. What is there to say, easy to fit and once installed it just does what it's supposed to do... what more do you need?
Mr malkinI have been using these bottom brackets for a few years now and have been very pleased with how they hold up, for a lower end bracket they are well made and smooth, very pleased with them
Mr NewtonExcellent service from Merlin as always. Cheap but good BB to replace same. If it last a couple of years as the last one did I'll be happy to replace it.
ChrisNIce and cheap so appeals to the tight a*se in me, but it has also bizarrely outlasted (~1 year) both XT (3-4 months) and XTR (6 months) bottom brackets so I only buy these now! (Mountain mayhem this year finished it off...). I don't mind the fact that they don't last as long as a Hope etc when they're this cheap. In some ways it's good because trying to remove a seized BB is a sod....
Mr kirkhamExcellent value for money, fast delivery, last as long as more expensive items.
Mr wilkesCheap as chips get roughly a year out of one of these why would you buy anything else.
Mr sheriffexcellent value replacement bottom bracket, easy to fit and set up
Mr Tilfordperfect value for money had one of these in my AM bike for over a year!
ResendeI bought this product but later I learned that I can not buy the crank without this component, but will serve me for future replacements. I'm happy for Merlin cycles and effective service for the price of shipping the product the same day of purchase. Thank you.
Mr llewhellinGreat product at a superb price. I ride singlespeed so go through bb's pretty quick. At this price, you cant go wrong
PaulUsed XT before they don't seem to last any longer so I decided to go for the cheap option which operates as smooth anyway and I can buy two for the price of one bargain ! usual prompt delivery and good service from Merlin
Mr HaslamJust replaced my origional deore bottom bracket after 12 monthes. Not bad for
Mr Talbot-Patersonsuperfast delivery, easy to fit and should last a couple of years
Mr southStandard part, cost effective can last me a year or two. Always Happy.
