Anyone use a TA Carmina? I'm considering the triple, as it's one of two options for a 185mm length.(High Sierra Cycles the other). But, I'm finding a striking bit of conflicting information on the web. Every web site I see in the US or UK says the Axix BB for it is JIS taper. A well known American web site web site says the crank is JIS. This makes no sense, as why would TA make their crank and BB with different tapers?

I also considered their Vortex crank, which clearly states it's ISO. Again, how could their Axix BB's be JIS then? Hmmm.


So, I email TA in France. It turns out they are aware of the mis-information being spread, as their BB's and cranks are ISO tapers ! This is from Amelie Nivart of TA.


The American web site states the Carmina triple takes a 119mm BB. TA says it still takes a 113.

Does anyone actually have one that they've installed recently? I'm rather confused and short of buying a bunch of bottom brackets, I don't know what to do. I really don't want to use an ISO BB anyways, as they are all very high priced, and I don't ride enough to justify a $150 BB and new tools for it.


The High Sierra Cycles option looks like it may be better as at least they know what taper and BB to use. The BB's are reasonable.
