Hi

Ive got a blakspire chain tensioner, bb mount.

I need to remove driveside crank and chain rings, remove the BB cup and replace a spacer with the chain tensioner, then put everything back together again.

My BB is Hussefelt Howitzer Race BB

Sram Ruktion crankset with bashguard (dual chainring)

Ive got a BB tool ( which i think plays its part when removing the BB cup to replace the spacer behind it) but no crank puller. It looks like its just a 8-10mm allen key hole in the crank, do I need a crank puller?

Cheers

    no puller needed. just undo the inner bolt.

    Im at work at the moment so I cant get a pic, but its similiar to this

    but where in that pic it gets shiny in the centre, its just a 8-10mm allen key hole, no detail just a hole if that makes sense

    well that is a link to lots of cranks.

    lets say you are more likey to need on than not.

    but without seeing YOUR cranks it is hard to say.

    Are they original to the bike? what make model year if yes.

    I think if you wait a sec, it loads a specific picture.

    I bought the bike second hand, so I cant say but I very much doubt it. Frame is orange patriot 7+ 2005

    I did need a crank puller, got one on way back from work. Got the cranks off and down to to the BB cup but can't undo the BB. Any advice on how to loosen/undo the cup? My bb tool is quite short so can't get a lot of leverage

    bigger tool. make an extension and check double check you are turning the right way.
