again fixing an older bike, just taken the Square taper BB out and found it's marked (and measures) as a CT91 116x68 but I can't find a 116mm ST BB on CRC/Wiggle or Merlin.
Does one exist, or should I just try and use a 115mm one or go up to a 118?
Sheldon site suggest the chain line can be between 47.5 to 50, so I'm thinking technically the 118 one is the way to go, but 115 is sooo close....

115 is only 0.5mm less each side. Unless you're VERY short on chainstay clearance, I suspect you'll be OK

thats a good point, though to be fair the 118 will only be 1 mm further out then, so @ 48.5 well within the chainline limits
(hadn't thought to split the figures - cheers for the heads up)
cheers
