Good bottom bracket at a great price. Seems daft paying more. Usual rapid service from merlin.

Silky smooth! Probably should upgrade my BB more often last one lasted for 6 years but difference is notable won't wait so long next time!

***** on 23/08/2014

Easy to fit and smooth as silk. Bargain!

***** on 05/07/2014

Absolute bargain. Cheaper than the Dura Ace unit I replaced, and hardly any heavier. All in a great product. Why would you pay more.

***** on 21/06/2014

Silky smooth! It's Shimano Ultegra so you expect quality in the build and materials and this ticks all the boxes. Looks good too which is always a bonus.

Replaced Shimano 105 BB with this Ultegra. Huge difference, now runs like a dream. I am a little surprised that the 105 only lasted two years worth of work commuting. Anyway, I like the Ultegra.

***** on 28/05/2014

Can't see but can feel the difference in quality versus 105 (still good). Great price - fit and pretty much forget.

Merlin are one of the cheapest places to pick up these quality Bottom bracket cups. My previous BB is currently going strong at 6000 miles plus. I've got a new frame so treating it to a few new shiny bits and the bottom bracket was something I didn't want to scrimp at. Trusted Shimano quality they stand up to the rigors of road cycling in any weather. Bearings feel smooth and the cranks rotate with ease.

It was a great price and an ideal substitute for the bottom bracket on my Sora equipped bike.
Easy to fit but please remember (unlike me) that not all torque wrenches work on left hand threads - almost disaster!
Weight is 90g compared to 95g on the Sora component it replaced so negligible saving but at this price who cares.

Not much to say except smooth as silk, cheap upgrade, do it!

***** on 27/08/2013

Bought this to replace my creaking bottom bracket and it's done the trick nicely, but now I can hear the other creaks and groans!! Delivery was extremely fast and the price was great

***** on 02/08/2013

Moving on from the square taper bb that came with the bike. A doddle to install. Very light and stiff (I've paired it with an Ultegra 6600crankset)

***** on 16/06/2013

Struggling to find something to say about this item. It does what it's supposed to.
Quality service from Merlin as always, despatched same day of order and arrived the next day.

***** on 14/06/2013

Super Smooth, and great value for money. A cheap upgrade over the 105 and lower spec BB's

***** on 13/06/2013

I was very pleased when I received this bottom bracket. Very easy to fit and runs very smoothly. Don't see the need to spend any more than I did, for dura ace, as this bottom bracket performs so well. Excellent product.

***** on 14/05/2013

Excellent product with fast delivery. The bearings are very smooth and would recommend this over the lower range products (Tiagra, Sora, etc)

***** on 05/04/2013

Great product and fantastic price and service from Merlin.

***** on 30/03/2013

I always go for the Ultegra bottom brackets as I find they last far longer than 105 and they're excellent value for the price. Never actually warn one out! Fit and forget, that's why I love Shimano.

***** on 19/03/2013

Straight forward a simple and easy replacement. Bike now running nice and smooth again.

***** on 12/03/2013

Great product, good price and swift delivery.

***** on 27/01/2013

A quality replacement for my old 105 bracket at a bargain price, received two days after placing the order

***** on 22/01/2013

Thanks for your speedy delivery and your rock bottom prices.

***** on 22/01/2013

Quality kit - Great price - Fast delivery from Merlin as usual! - Simple as really.......................

***** on 22/01/2013

Excellent piece of kit, extremely light and with the Ultegra name should give a quality performance.

Very easy to install with an instant change of the feel of the bike - more secure.

Would buy again..
