I'm not a fan of this pressfit type bottom brackets. They are extremely hard to service, without proper tools, and wears out super fast.THis one seems pretty hard to rotate out of the box, after install the slx cranks does not really turn more than 1 rotation if I spin them without the chain.At least it's not too expensive, so you can change it every year if necessary, I'm curious if it can survive the winter.

Excellent bit of kit from Shimano. (As always). Superb service from tredz. Arrived well packaged and in a timely fashion.Would definitely recommend tredz. Have used them in the past and never been disappointed.

Look I'm not Lance Armstrong , so for what I'm doing on my bike this was a great inexpensive replacement bottom bracket, so far it's been quiet and smooth. Only time will tell if it lasts though and so far I've only ridden it a couple times.

I don’t write reviews normally, the I need to sort a problem bottom bracket and the Tredz team were great. I had a great web-chat with 1 of the team to confirm the part I needed, I then ordered it without problem, and as they said it arrived well packed and slightly earlier than I expected.Bike fixed and back on the road.Great service - thanks to all at Tredz
Got a trek domane 2.3 which obviously has a very awkward sizing. Brought this to replace, haven't looked back since. Very fast and efficient from sigma sports on the dispatch.
I usually buy Specialized grips, but thought I would give these a go. I was not disappointed. They are well constructed and very comfortable. Great Value just under 6. I click and collected them from my local branch of Argos, so no waiting in for a delivery or having to traipse up the Post Office the next day. I got a text message when they had arrived and went to collect them at my leisure. I would highly recommend these. They are just as good as the usual Specialized grips which retail at twice the price. I am very satisfied with them.
For the comments of my BTT friends, there is nothing to envy to the MAXXIS brand, a tire to place behind if you do XC, the price of the cheapest website I have seen, the shipping with lousy MRW, but the product very well. I like bikeinn.
Press fit bottom bracket supplied as requested, quietly efficient……..wish I could say the same for the press fit standard!
Had an issue regarding the bottom bracket on my BMC (original bottom bracket appeared to be slightly too small for the shell). I purchased the SM-BB71 bottom bracket and it arrived within 3 days. The item was well packaged and was exactly the dimensions specified with no imperfections. Easily fitted and the bike feels like new again
Wow! Used 'em all... this one is the best. Can't say enough. Giant TCR Advanced 1 and this makes it all happen. It's fun to know you can upgrade to this quality and improve everything with such an affordable price. Highly recommended.
