Actually, if you dig, Cervelo recommends less than 80mm (std 15 top cap plus 3 10mm spacers, then stem) on the Wolf SL fork. This coincides with the 125mm aluminum sleeve that gets epoxied in during installation. There is no min for the CL. I was WAY below that though with only the 15mm top cap and zero spacers.

I'm getting quite the steerer tube education here (with ice on my knee) :-(

Anyway, for others that ride hard and have some miles on ... go check your steerer tubes tonight!!!
