Square taper BB Help please !

(1/3) > >>

NORTY40:
I have a crank set that needs a 15mm (measured across the flats on the sq taper) axle . The normal sq tapers for Sugino GT's/Takagi etc use a 13mm taper across the flats .

Can anyone point me in the right direction to a BB or even better has one that measures the elusive 15mm acoss the square taper flats for sale.

Any help would be appreciated  :daumenhoch:

This might be a long shot, but try a Raleigh dealer with a workshop. They used something similar on their early mountain bikes, say a Lizard. It had a US bb with a three peice crank, also poss a Mustang too, but I had a lizard so know first hand.

Thanks for the reply mate  :daumenhoch:  Can't see any bike shops were i live having anything but it's worth a try i

I was wondering if some other cranks used a similar size  :-\ 

Anyone else got any suggestions, pointers or solutions  ???

Did a bit of a search on here and i may have found something  :)

Looks like the Redline 400 cranks came with the larger spindle (15MM across the flats possibly :-\) ...... could someone who has a set of these do me a big favour and measure the square taper for me please .

Thanks lads  :daumenhoch:

When I saw the thread I knew you'd be after a square tapered  BB for either HLT or Sugino/Redline 400's Joffy


Hard to come by on their own mate , but now and again  :daumenhoch:

There's a guy called Cuckoo on here and Museum (Lee) , he did  excellent reproduction 400 BB's for about £75/£80 at the time .
 I think he's in the Far east , he's a good fella  :daumenhoch:
