Power meter options for SuperSix

papajimbo

I’ve got a Supersix Evo with eTap and an SiSl2 chainset and have just returned a set of Vectors as they are faulty. Now considering Quarq Dzero SRAM or a Stages Cannondale Si. Clearly one means swapping out the chainset whereas the other retains the original at the exepense of not measuring total power output. I know from the Vectors (while they worked!) that my l/r split is even - though not ridden over 4 hours with them so not sure when I’m fatigued.
Any experience of these options and thoughts on the better option? One consideration with the Quarq is I get a full component for a not dissimilar price.
Both would mean having to use a BSA/BB30 bottom bracket if I wanted to use them on my winter bike - does anyone have positive experiences of trying this?

One-sided measurement could be fine, depending on whatever it is you need the power number for - ie leisure, training, consistency or absolute scientific accuracy.

I have a quarq (sram red) and have never had issues with it, I don't know if is just a psychological thing but I do feel more confident in it's accuracy giving dual sided readings. One thing to note, it does add a little bit of extra weight aroubd the bb which I do notice. Personally it does not bother me but for some it could be an issue.

The SiSL2 chainset is a thing of beautiful design and manufacturing
Powertap G3 hub is your answer

I went for a factory fit 4iiii precision on my sisl2 chainset.

Power2max do one for the SISL2 crankset. I have a set of Vector 3s for my Evo, not used them yet hopefully not faulty.

Some good deals on the Powertap P1 pedals on EBay at the moment. DC Rainmaker rates them highly and there have been 3 sets sold at sub-£500 in the last week (from Wiggle and Tredz via there Ebay accounts).

Offer easy switches on to different bikes and dual-sided, strong accuracy levels and decent data output. Worth a look.

Power2max NG Eco and keep the SISL2's - Think they are around £500 new and are bomb proof, reliable, accurate power meters.

You used to be able to buy a Quarq Spider that would bolt onto the Cannondale cranks but I can't see it listed anymore. Perhaps it's worth keeping an eye out for one as I would avoid Stages.
