    Can anyone help?

     

    I am looking for an uprade in the BB for my Boardman, I have purchased the Rotor 4630  BB, which is a straight swap, however it won’t fit in the Boardman (checked with LBS) 

     

    The boardman frame has a taller than usual internal lip meaning the rotor bb won’t push in as it butts against the lip.

     

    Has anyone changed the BB on this bike? 

     

    I have been through many BB’s and it seems pointless to keep fitting the same PF30 thats made of cheese?

     

    Thanks in advance

     

    I forgot to mention I still have the FSA gossamer crankset on.

    Excellent. Enjoy!

    @jollygoodvelo the Microshift front mech became an Ultegra one the day I collected the bike.

    My previous C2W bike was a Boardman Hybrid, so I removed the weakest link in the groupset before it became a problem.

    I’ve got the same problem with my CX, might have to give it a go.  I’ve changed pretty much everything else recently 😀

    Follow up post: did it.  Hardest part was getting the old PF30 cups out of the frame and getting the BB adaptor in straight.  Now smooth, silent, wonderful.  Hurrah!

    Tiagra chainset, Microshift

    Tiagra chainset, Microshift front derailleur and Apex rear.  Well, I suppose that’s the advantage of interoperability…

    Having tried various replacement PF30 units and bearings with and without grease/liquid torque I finally gave up and did something very similar to cxr94di2, although it came from Planet X.

    Currently only 8 quid, so while getting the URL I’ve just bought a spare as it includes the outboard bearings!

    I whacked in a Tiagra compact chainset and for £60 all in finally bade farewell to the PF30 nightmare on this frame set. Been running beautifully for 6 months now (100 miles of all weather commuting per week)

    I moved over to sram cups which allow me to use threaded external shimano bearings. I did this to stop creaking
