I have a 2013 Norco Threshold C2 cyclocross bike, and I’d like to put a power meter on it. After some digging, it seems like the new SRAM Rival AXS power meter is a good fit, or rather, might be a good fit.
I’ve had this bike for a while, and I enjoy tinkering, so it’s had a few different cranksets and drivetrain configurations over the years. It came with an FSA Gossamer 2x10 crankset, which I replaced with a Shimano R7000 2x11 crankset, which was then replaced with an AliExpress ZRace RX crankset with a 42T ring. I’m now looking at moving over to one of the new SRAM power meter cranksets, as it appears that it is compatible (appears is the key word…)
I’ve had a lot of trouble locating specs for the bike and parts. For example, I’m able to measure my current the chainline (measured at around 49mm, but my tools don’t allow for a ton of precision here), but I’d love to know what the chainline is supposed to be from factory. Similarly, the current Q-factor is 148mm, according to an AliExpress listing I found, but in this case, SRAM doesn’t list a Q-factor for their Rival XPLR AXS power meter or crankset, so I don’t know how the new crank will compare with what I currently have from a biomechanical perspective.
Is there some magical resource somewhere that lists all these specs for different frames and parts? Shimano lists both Q-factor and chainline on their specs, but SRAM doesn’t. Norco doesn’t seem to offer that information either.
Or is all of this dumb and should I just spend twice as much on power meter pedals?
Thanks!
