David LynchFantastic value for one of those items you want to fit and forget. This purchased for a Deore Groupest as upgrade on the BB51 supplied (Fully cross compatible). Alloy housings and spacers. Well packaged with good instructions . Installation was very straightforward. Bargain, Thanks Merliln :)
Mr McDonaldReasonably light, easy to fit, good value. Got 5 years of filthy maintenance free all seasons riding from the last one.
HadlerGood quality bottom bracket, well made and reliable
Mr WhiteleyExcellent bb the bearings last for ages. Shimano quality! and Merlin rock bottom price.
Mr ThompsonXT bottom bracket - does what it says on the tin - reliable, easy to replace bearings if needed (never had to though) and a good price. Great service as always from Merlin Cycles - one of my favourite bike component suppliers!
Mr FisherJust replaced my old one which was the same and had no problem, it lasted 18month and 1500m of reasonably rough riding, I'm happy!
Mike the BikeThis product seems to have got better over the years from its earlier incarnations which didn't last long. Easy to fit with the right tools and lasts provided the BB is faced beforehand
Mr HillGreat value for money and long lasting. No need for so called higher quality versions in my opinion.
Mr PriceWent for the XT as the Deore only lasted a few months (though this could have been my fault for tightening up to much on the bearings). No external difference to the Deore part. Assembly straight forward with the correct tools.
Mr ThompsonUsual Shimano quality, simple to fit with clear instructions.
Mr MatthewsDoes the job well. Didn't quite realise how knackered the old one was until I replaced it. Chosen following prompt advice from Merlin. Usual fast delivery.
Mr Jackson3 years of hard riding through all sorts of condition is the only reason I need a new one! Great durability with the normal Shimano quality - wouldn't consider anything else
Dr MeadeReplacement for the original BB for XT chainset. If this lasts the 3 years the previous one did then its a bargain.
Mr CaseExcellent service as usual from Merlin. The bottom bracket does what it says on the tin. Easy to fit and runs smoothly. My only issue is that these components are not really fit for UK use. Inadequate bearing seals inevitably lead to premature failure. Decent sealed cartridge bearings would not add significantly to production costs.
Mr lilesbomb proof and last 3 times longer than bbs costing 3 times as much
Mr WaughReally good bottom bracket and has now lasted nearly a year of riding, terrain varies from the Peak district to Trail Centres so it has seen varied use and is used most weekends.
Mr StockI can't report on longevity yet - but they are easy to fit, light, and ride well.
Mr smithTop quality bottom bracket only took half an hour to install Super fast service from merlin
Mr squireLasts as long as more expensive product. Great
Mr KingGood value BB and great quality too. The first one lasted just over 2 years on my teenage sons mtb and boy did that get some abuse. Easy to replace, instructions on You Tube.
Mr MorrisNo problems fitting the new BB - quality bit of kit with superb service from Merlin. Very Happy :-)
Mr suttonitem ordered was as stated now fitted by myself and working smoothly
Mr BellGreat service - as usual BB easy to fit now silky smooth. Thanks again Merlin
Mr MillsBought a deore bb50 to replace my bb70 it lasted 2 months where as my bb70 had lasted 2 years so bought one of these excellent bb and best price could find its a bit more expensive than bb50 but well worth it buy this do not buy a bb50 you have been warned!!
Mr clowUsual great service from Merlin - lowest price and speedy delivery
Mr RavenEasy to install and well packaged. Light enough for my mountainbike and looks up to the job.
Ted DurrantI like everything about this bottom bracket except the spacer rings. If your setup allows, exchanging the two thinnest for a regular spacer avoids some potential problems. Otherwise be really careful during installation.
Mr millsLight and easy to fit (with the right tool). I get through one of these each year but thats riding twice a week
Mr JonesGreat Item at a great price. Superfast delivery too. Can't ask for any more.
Mr PenmanDoes exactly what it says on the tin....Shimano quality at Merlin prices...what else do you want or need.
Mr WeissOrdered as replacement for 2 year old version. Hopefully this one lasts as long.
Father ZedI bought this as a like for like replacement to fit on an Orange 5. My previous bottom bracket lasted a couple of years on 2 bikes before starting to run roughly. I have run the new one on a number of rides now, including a weekend of trail riding at Afan. It is simply faulteless, running smooth from the off. These are also very easy to fit needing only a BB tool, and placing the correct spacers on the cups. A really good product at a great price. Thoroughly recommended.
PaulReturning home from a long ride at the weekend I realised that every single pedal stroke was accompanied by an arthrtic creak, signalling that my XT bottom bracket had begun to wear out. After the initial cursing, I realised that this very same bottom bracket had been in place in my frame for two and a half years, having just seen off it's third summer. In that time, I've ridden roughly three times aweek on average, having covered well over three thousand miles through mud, deluge and grit. Not bad going for a throwaway part by any measure.
Mr LockhartLast one of these suckers lasted from 09 till now... From merlin cycles, rode every winter too and been on three bikes. Hoping this one stands up too! Broke it in at glenyrrss and inners and worked smoothly :)
Mr MillburnGood product, cheap price
Mr JolleyDoes what it says on the tin, although a few odd grinding noises only a week in. Could be pedals so this review may change.
Mr FruitbatThe BB70 is by far the longest lasting HT2 for those on a budget.
2damfasLast one lasted about a year, inexpensive and work well. Exceptional service and delivery from Merlin.
Mr TedhamEasy to fit amd smooth
Mr MaKOld one lasted 15 months all weathers, so I didnt do too bad! I will see how we go on this BB..... next time I might remortgage and go for a nice Hope ceramic upgrade : ))
