PowerTap G3 Disc Hub


Hub power meter for MTB wheels.

Compatible with 135mm quick release or 142x12mm thru axle options.


SKU: N/A Category: Tag:


The G3 Disc Hub is lighter, smaller and stiffer than ever before. We took our original disc hub shell and shaved off 180 grams, aka: 30% of the weight, and incorporated a 6 pawl freehub for faster engagement and an even longer life. Ideal for bikes with a 160mm rotor, the G3 Disc Hub can be used as 142x12mm thru axle or 135mm quick release for a wider range of compatibility.
