RACE GEARING HELP / SRAM OG 1090 v PG 1070 FREEHUB COMPATIBILITY ISSUES
Has anyone experienced free hub compatibility issues with SRAM between the OG 1090 and PG 1070?! I've noticed a different spine pattern between the two and I need to rectify the situation soon. PLEASE HELP!! I'm running into a tight timeline and I am kinda freaking out!!!
I run (circa 2009) Sram red on Zipp (2015) FC 303s . I have a powertab on the rear hub with a straight pull PT freehub. Living in the desert I ride a tight 11 x 23 with a standard crank that suits me quite well. Going to South Africa (a bit similar to IMWI) for IMSA on 10 April and looking to switch to my 12 x 27 cassette.... turns out I I left my 12 x 27 cassette back in the states (awesome).
I purchased a new SRAM PG 1070 cassette (11 x 28) and it will NOT fit on my powertap freehub.
- The spine gaps on the SRAM PG 1070 do NOT in any way match up with the powertap SRAM freehub
- The SRAM OG 1090 (11 x 23) spine gaps do NOT match that of the SRAM PG 1070 (12 x 28).
- The SRAM OG 1090 (11 x 23) fits the SRAM PT freehub like a glove.

I will go to two of my LBS tomorrow. I was not able to get any answers today as most shops are closed on Friday. Hoping to get some direction here.
have a good South African ironman.
I might consider doing this next year.
