I need a new bottom bracket, I have a 2010 Specialized Rock Hopper, with Shimano Deore arms with a hollow crank outside races.
Can you recomend a "hope" replacement bearing set that fits the frame BB is about 66m wide the dia of the thread section is 35mm and the outside flange is about 44mm. I liked the SS one for £57 but note sure which version to order. Thanks

These are beautiful bottom brackets that run silky smooth so a great choice. The size you will want is the 68/73 in what ever colour you like. They come with 3 2.5mm spacers so that it will fit your 68mm shell or if you ever have a frame with a 73mm shell you can just take it out, remove 2 spacers and fit it into that new bike. These bottom brackets really do last with an absolute minimum amount of servicing. Your crankset will work nicely with as well, just take care when installing that the axel is lined up when you go to knock it through the second set of cups (you don't want to damage them). I just use a soft face mallet and gently tap if it needs it.
