Changing bearings in a Powertap G3 - strictly a back to Saris affair?

Would that spider fit on a force 22 crank arm?

Yes

Weird. I was told it wouldn't, a few months ago, unless that's a new spider design.

Tempting...

fucking 'ell

AIUI, Saris says yes, many Interneterists say no. I can't, for the life of me, see why changing the bearings in a Powertap hub shouldn't be a DIY affair.

P.S. Someone from Powertap said on the DCRainmaker site that 'We don’t like bearings to be replaced in the field more for the sake of the bearing than anything else.' WON'T SOMEBODY THINK OF THE BEARINGS!!!!

Sram rival and force both use the same spider as far as im aware?

But 22 and 10 speed Rival/ Force- is there a change in spider design- is the question I think @Howard is asking.
(I'd also like to know).

Thats the 11 speed crankset no? The 10 speed didnt have a removal spider

Sram rival 10 speed

Sram rival 22

P2m deal

Apologies if I'm barking up the wrong tree

Yeah that's the latest Rival by the looks of things.

As I understood it, there was a P2m classic that fitted the old S900 crank which had a different spider design to the S975 crank that the Force 22 crank is based on. At least, that's wat P2m told me. As I remember it I don't think there was a classic for the S975, but happy to be corrected.

Good spot. Excellent news.

Bearings sit in hub shell and have no interaction with torque tube so tap axle out as for any other Novatech manufactured hub.

Don't know about all of that. Weren't there two iterations of the classic?

Regardless, it clearly fits the rival 22 crankset so you're good to go with a force 22.

Have you done this before?

If so, fancy doing it again?

I have but would only do it to my own hub #hammer

Equally awesome and anoying

Why annoying? Buy buy buy

I'm trying to buy things that increase my lolz, not my suffering

Know of anyplace in town that would do it? I asked Soho Bikes, but they haven't responded.

What size bearings are they? If they're 17mm ID/26mm OD then I could lend you my bearing replacement kit - expanding punch for knocking them out, bearing press and mandrels and some machined blocks to rest things on.

Sam at LMNH can do it, I can just drop the bike in on the way to work, thanks for the offer but my laziness wins this one.

Just got my Garmin Vectors back after sending them in about a battery issue. They seem to have been magicked into Garmin Vector 2, which is nice.
