What power meter would you choose?

[Gardengnome]

Hi
I have been searching and researching about power meters for a while. Looking for one that will work on my winter bike, that has Shimano gxp and my summer bike that has Sram red22 bb30
The 2 power meter i have been thinking of are the powertap P1 pedals or converting the winter bike and using rotor IN power. Any thoughts or advice anyone can offer?

I would choose . . . . a better matching title, so readers can see where this topic is about without opening.

Sorry didn't really give it much thought!

Rotor Inpower

Why don't you get a power2max with rotor crank? Same crank but power from both legs and a lower price to boot.

+1 on power2max.

[Gardengnome]

Will the power2max still work on a bb30 frame and a gxp frame?

You have internet right?

I do not fully understand the chart. Will it work with a bb30 gxp setup? Thx

Here's rotors compatibility chart

So bottom line is both the 3d and 3d+ are compatible with both, assuming appropriate bottom bracket selection

Just a point of clarification: gxp is sram's name for it's bottom bracket/24mm spindle cranks.

I would advise getting a used Quark. You can get one for 700 or so on eBay right now and you'll get both left/right power plus a good crank in itself.

If it's a pure Weight Weenie decision:
- Stages only adds 20g to the crank
- use smartphone app to record data as you won't need to add a head unit to the bike

If it's a performance decision and you wish to see data as you ride:
- Stages 1-leg system wont be the best for data & you'll never truly know your imbalances. Worse, once you realize this, your imbalances may radically change due to subconscious overcompensation.
- SRM wired systems are known to be bombproof and reliable almost forever. I know many models circa 2005 that are still in use now and it'll hold up fine as long as batteries/calibration are kept on top of. Dead cheap 2nd hand if you use the Google wattage group or check eBay.

Can't believe how cheap the fsa version of the power 2 max is very tempted to get that now

Thanks! Just finished ordering a power2max!
