Just got a powertap g3 hub. It’s the disc version so I think it’s 135mm. However my road bike is 130mm (non disc). The guy I bought it off was using it on his 130mm road bike. I can fit it on mine with a bit of trouble but once it is in it seems fine - it may have a 130mm adapter on it…I don’t know
Is there an adapter to make the 135mm hub version for 130mm standard road bikes?
Is that adapter already on (see pics)? Once it is in it is tighter than my Other wheel but if I have qr loose it does fall out from gravity suggesting it isn’t pressing against drop outs too much
Bending frames is (in general) not a great idea unless the frame was built for it (like Surly’s nitty gritty 132.5 mm spacing but it can work in some cases https://www.sheldonbrown.com/frame-spacing.html
As for the hub over-lock-nut-distance, the easiest way to figure out is to measure (see above link) and whether or not there are amy adapters/end-cap options I’m afraid you have to check Quarq PowerTap G3 Disc Hub | HU-PWTP-G3M-A1 | QUARQ | Service
You can’t adapt the 135mm disc version to a 130mm OLD.
The frame will be stretched out to fit that wheel in. It’s not ideal and theoretically voids your warranty, but I can’t imagine there are any 130mm bikes left with a warranty still in date!
If it works I’d be tempted just to ride it but be very aware it’s putting the frame under a bit of stress it wasn’t really designed for (specifically the dropouts are being bent around the hub end caps).
Are you sure? Came with disc when I bought it today although guys road it on his road bike. It also looks like the disc brake version rather than standard version on sram website
Ah, that changes things! I didn’t see a disc and the mounts weren’t super obvious. In that case the above is right, it’ll be stretching the bike. Since that hub is worth more than the standard one and rarer, I’d sell it and buy the right one - the hub on my case as a build wheels, but maybe full wheels in your case if you don’t want to get involved in that!
SRAM sells the 130mm for your road bike…But I could really use 135mm end caps for a G3 mountain bike powertap…do you have the bolts for the disc to attach to the PT hub too?

I’ve got 2 of the G3 hubs in straight pull, not the disc versions. I believe they used DT swiss internals and they still work great (although I’ve had to replace the electronics cap on them). They weren’t around long before powertap tapped out, but they were basically giving them away at the end, cheaper than a quality rear hub and not much heavier. They are on my road and TT bikes which I’m good with rim brakes, so plan to roll the powertaps as long as they work. I’ve switched to quargs many years ago on everything with disc brakes
