Square taper BB Help please !
« on: November 07, 2012, 05:50 PM »
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  :)

http://www.radbmx.co.uk/forum/index.php'topic=26518.0

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:

Thanks Christian  :4_17_5:   there not for a HLT crank or a set of 400's but something just as nice and rare too  :-X 8)

Sounds like it could be a long search  ::) :D Thanks for the pointers though , i'll try a wanted on here first and see what happens .

Do you know for sure or anybody else for that matter that the 400's axle measures 15mm across the flats ??

Thanks

i needed an axle for my redline 400s and searched for a couple of years before i found an original one, then about a week later cuckoo had them for sale. they look really nice too. i used a coke can to make small shims and a normal square taper axle till i found the correct one. worked fine too, it was nice and tight.

The alloy fusion cranks have a 15mm square taper.
I'm sure the group 1 steel cranks used the same bb and bearings.  :daumenhoch:

I had thought of that myself as a quick fix as they are only going on a carpet queen ...... it might have to suffice for the time being  :D Cheers John .

Do you know if the alloy fusion bottom brackets are available anywhere Stu  ??? or are they a pig to get hold of too  ::)


what size are the pro-class spindles?

Not sure , i can find out though as i know 2 people who have sets of them  :daumenhoch:
