Upon learning of the new system SRAM announced recently it was nearly impossible to avoid daydreaming about the possibility of running a 36t chainring (I run a 32t today) while actually improving the climbing gear ratio. That’s just incredible. Never mind that probably the most important advancement for me, assuming true, is the improvement in durability (see 1×11 Drivetrain Competition) .
If this new system is in fact more durable and the frequency of replacing chains and cassettes is reduced enough the total cost of ownership would go down (even though the initial cost is STEEP)!
All (most) of this is really good news.
And now for the bad news. I just heard back on my inquiry to Quarq and was informed their XX1 power meters are incompatible with the new Eagle system and at this time they “have no announcement about a replacement”. So if you are an XX1 user today with a Quarq power meter, at least for now, it seems you must choose between riding with power and the new 1×12 SRAM system.
