I can't bloody find one anywhere!! Tried most of the big on line shops.
I'm after a square taper bottom bracket 68mm x 103mm
It's for a specialized Langster. I bought a tange one on ebay and they refunded me saying they've run out of stock.
any help I'd be grateful!!
Haven't seen one in that length for years, you could try getting the old out, nipping down to the LBS and comparing it to 107mm.
Overall axle length doesn't mater too much, what matters is the amount of axle showing from the driveside cup for good chainline. A Shimano 118 for instance is 1.5mm longer on the drive side than an FSA version.
It's from a 2008 Specialized Langster, i'm surprised is so unusual.
Its a single speed, so am I right in guessing if the chain line is slightly out it isn't all that much of an issue?
Not really, obviously chain/chainring wear will be at a higher rate.
campag chorus / record 10sp sq taper are 103mm so without doubling the value of your langster with a carbon record bracket - look for token - they do some that short
What cranks are you running?
cranks are sugino comps.
my '06 Specialized transition has the same size BB.
I just went for a new external crankset in the end, as I gave up..... though the cartridge bearings in the FSA i had can be replaced if you can find a good supplier. someone like GEM rewinds can replace the bearings.
Just a thought.
thought apreciated. Cheers andy.
We may have one in the workshop, the size is definitely ringing a bell. I'll check in the morning and put in a post(memory permitting). Pretty sure it'll be a Syncros cartridge bearing jobby if it's still there.
Campag do a 102 as mentioned above but it's a slightly different taper so doesn't give quite the same chainline.
Strangely enough, you may get away with it, as Sugino may be the exception to the JIS/ISO conflict. From Wiki:-
Not all square taper crank and bottom bracket combinations are compatible. Although nearly all spindles use a 2 degree taper, there are two competing standards, defined by the measurement across the flat at the end of the spindle. The JIS size is used by Shimano and most other Asian manufacturers. The ISO size is primarily used by Campagnolo and other European manufacturers, in addition to cranks that adhere to the NJS standards (Sugino 75).
coatesy, get back to me if you have the syncros in stock please.

I may have a look at the campag route if all else fails.
Though looks like evans may have a Token jobbie in stock on the 30th.
thanks for the help!!!
