Hi all,
Thread revival but it seems the most appropriate place for a PM discussion.
So… I have a new bike with a SRAM XX1 GXP boost crank and WheelsMFG PF92 BB and I’ve already gotten the training* (*man I hate that word) bug again.
I have 3 options:
1) Stages SRAM Carbon left side for £400 as an out of warranty replacement for my now dead first gen Stages SRAM X9.
+++ Cheapest option and easy to fit.
— Cranks won’t match (not too fussed) but main thing is just measuring the left leg. May well die without warning.
2) Power2Max NGeco SRAM Boost spider for ~£550.
+++ Not toooo many more pennies than the Stages but measuring net power this time. Seems fit and forget (at least previous versions).
— Will that flappy rubber battery cover really last MTB through a British Winter?
3) Quarq XX1 DUB crankset and ring for ~£700.
+++ Seems fit and forget and all the benefits of the P2M without battery sealing issues. Has a few more features but I’m not sure I’d use them too much.
— Requires new chainset as the spider is 8 bolt not the standard 3 and required new BB as they do them in DUB only. The WheelsMFG DUB BB is apparently very pricey. Even at the cheapest its another £35 or so for a SRAM PF92 BB so the pricey option is even pricier.
So… I’m leaning towards the Power2Max NGeco as the best balance of everything but does anyone have one or have comments on the battery cover? Is the Quarq really worth the ~£200 premium just for peace of mind???
WWSTWD? 😀
Cheers!
