Has anyone ever tried using a JIS taper crankset on an ISO tapered bottom bracket?
From my research into the actual physical dimensions of ISO and JIS spindles, I think that the two should be pretty interchangeable. If you use a JIS crank on ISO spindle, you need a spindle size about 4-4.5mm wider though. It seems that a lot of people on forums say it won't work, but I think most haven't tried it.
I need a new BB anyway, but also figured that while changing it, I want to save some weight on the part. My current BB is 350g. My Team Marin is hovering just above the 9kg mark and a lighter BB would get it under :twisted:. I'm considering these two which are a bargain for the weight:
This Neco one. I'm unsure yet whether this is JIS or ISO, but have messaged the seller to ask. 223g
This Tifosi one
There was one made by token which was 113mm JIS, but unfortunately it's been discontinued.
Is this a bad idea? If it helps, I don't plan to be removing the chainset very often at all. My crankset is a Deore LX M563 Triple.
