I have read on various vendors sites some variations in the distance between clamps for the lefty's
I want a lefty Ultra Carbon SL 120 to fit it to my Nicolai RC, which has a 115mm HT.
Most sites show a 137.7mm distance. I am sure one showing 138.7 (could be a typo).
So I have 22.7mm to play with!
I have few very low stack headset choices but the three most likely are a
Tune Bobu at 24.4mm incl topcap (so a little lower w/o topcap) One other person has used this headset but in theory it shouldn't fit unless the top cap is 2mm thick!
Crank Brothers Directset at 20.5mm (This should fit nicely within the 137.7mm quoted)
Or Acros AH-01 at 23.1mm which again in theory is 0.4mm too big!
If I can I would rather not use the directset due to reported issues with longevity but, if I have to needs must.
I am just after confirmaion of the maximm distance between the clamps!
Oh and if anyone knows if the 2011 Ultra Carbon SL PBR is actually available anywhere?
