I got a powertap G3 in October from my LBS.
Around Xmas I noticed that the bearings weren't smooth and felt a bit dry, and now there is some play in them, noticable with the wheel in situ by rocking side to side, but also noticable in the freehub by rocking the big sprocket on the cassette.
The wheel has been used for 10-14 hours pw in some nasty weather for the 16 or so weeks that I've owned it.
I'll give the LBS a ring about it, but wondered what I should expect, has anyone else had this, are the bearings straightforward to replace, are they just standard bearings that the LBS should have on the shelf and should I expect it to be a warrenty replacement?
Something else to checkout is the end caps on either side of the powertap, try wiggling those and see if they seem loose.
Why do these bearings wear out quicker than other
I've used some £70 shimano r501s 5 times more and the bearings are still fine.
I spoke to the LBS earlier and they basically said they'll phone powertap tomorrow and see what they say, but don't hold your breath as bearings are considered to be consumable.
Any clues on cost of bearings and time to replace them?
The main issue with the PT hubs is they come fitted with really rubbish bearings! Cheap and nasty old things that corrode as soon as you get a sniff of water in the air. The standard bearings are junk.
This combined with a pretty average design means they will wear out very quick. Send it back to Saris and you'll get another set of junk bearings fitted that'll need replacing in roughly the same time period in the same conditions.
I used to do lots of PT builds for people and became quite experienced with the ins and outs of them.
If you're in the UK http://simplybearings.co.uk/shop/ These guys have everything you need.
If you're in the US there are loads of bearing shops online.
My advice would be to go for a high quality bearing that is water resistant (you can pick up what is effectively a stainless bearing set for not much money, just check the specs and look for blue seals) Fit them carefully and you'll be good for a couple of years at least.
The PT hub is a doddle to work on, very simple design, no problems.
I think I have the sizes and bearing codes around somewhere if you need them, but best solution is to remove and measure.

I think your solution is by far the best, open it up and upgrade straight from new.
I was never really in a position to carry the responsibility of potential warranty claims so never really had that option until the warranty had expired....but it's the only way to produce a reliable working hub for the UK conditions.
I used to get guys coming back with knackered bearings after a matter of weeks sometimes, very poor show on the part of Saris (given the retail cost of the unit). It would have cost next to nothing to spec a better bearing at the point of manufacture and would have promoted a better reputation for quality.
The increase in customer satisfaction, market image and reduced costs of not having to repair so many hubs should be a no brainer in my eyes?
To be honest I don't miss all the hassle of dealing with firms like Saris, problematic Tune hubs, faulty rims etc. So much aggravation.
Apparently they wont let the LBS touch it due to the warrenty, and when I spoke of my suspicion that they'll stick another set of naff bearings in they said that they've said they'll replace them with some SKS ones.
So I'll wait til Monday (start of rest week) and send it back.....
@legs 11 have you got the sizes of the bearings available? I need to refresh mine before I sell them. Going to move to Stages I think.
