started the strip yesterday on my Raleigh Triumph Twenty Tragic Master, it weighs a ton, but once strippedm the frame isnt that bad! i need someone though, near south wales, who can retap the crank and shave the bb by 5mm, argos bikes want 150 quid, to resleave it, then cut it. will be a top job, but a bit much on a cheap bike.

How much thread is cut in the bb already?
I've narrowed these bbs before, using an angle grinder rather than wearing out a tool that costs us £80 to get resharpened. I just use that to level it off.
But if you need to cut much thread in the bb, most workshop tools are for chasing, and again you end up having to get the tool sharpened.💰

I think argos are milling out the old threads and glueing in a sleeve - this avoids the possibility that the 68 Threaded section is tangling with the Chainstay area, and is the proper way to do it.

Cheapskate method would be to grind the ends down and fit a self- tightening square taper unit.

You could always blow the big money on resleeving after Luckyboy romps home at 20:1 in the chepstow races?
