Fugit. Icon started flashing again today, ~5,390km. Tried to check the batteries in my $149 tester/charger... and it smoked itself. Luckily it comes with a three year warranty and I still have the receipt.twizzle wrote:I checked the batteries on my expensive tester/charger... and they both came in at 70% charge. I'd already bought replacements, so I chucked them in and I'll see what they get down to before the icon starts flashing again.
I've swapped the batteries from my spare hub in, I'll try and get a refund for my tester/charger tomorrow and get a new battery tester. Battery life in the comp hub is not looking good. I'd better stock up on spare batteries tomorrow as well.

I've got new batteries and have bought a battery tester (my expensive unit has gone off the be examined/repaired/replaced/something), so I'll check out the situation tonight.

No idea why the unused hub had flat batteries, the batteries are supposed to be good for five years of storage...

Has the hub got an on/off switch? If not, obviously take the batteries out when not in use.twizzle wrote:No idea why the unused hub had flat batteries, the batteries are supposed to be good for five years of storage...

The locknut on the non-drive side had come loose (blue loctite showing on the threads) and was allowing everything to move a couple of mm. Pulled the axle, cleaned out the ratchet mech and re-greased it then loctited the locknut back in place. Had a bit of fun doing up the locknut as I don't have a 17mm cone spanner, but I used two allen keys as spacers for an adjustable wrench on the flats and was able to tighten it that way.

Probably - it has the 12mm steel axle which is threaded on each end, and the freehub just slots into the end of the hub then the axle goes through and hold it all together. When I rocked the wheel on the bike, you could see the cassette moving relative to the hub - I though I had broken the axle! Very distracting in the race, first I had gear selection issues and a couple of times when cornering hard it felt like a flat tyre.toolonglegs wrote:Are they different in the other models?...my free hub just pulls off,no nuts holding it.

OK,the 15mm axles models must be different then...similar to older DuraAce 15mm set up with only the quick release holding the free hub body on.twizzle wrote:Probably - it has the 12mm steel axle which is threaded on each end, and the freehub just slots into the end of the hub then the axle goes through and hold it all together.

I've stuck to using the Garmin for cadence as the PT cadence from the hub is pretty unreliable (stopped at lights with a foot on a pedal and it shows cadence being recorded) so I think I'll fit the wired cadence sensor to the Giant and switch off the hub cadence. I have wired on the Bennett, but I don't trust that it's using it all the time.

And the transmission icon started flashing on the trainer tonight at ~6250km, and then it started cutting out on the transmission altogether. One battery at 1.4v, the other at 1.26v. New batteries again... cheapo brand ones are obviously NFG. I'll get some decent ones on the weekend.twizzle wrote:O.K. - new batteries for *both* hubs. Both sets of batteries reading 1.36v, down from the initial 1.5v they are supposed to put out. So I'm going through a set of hub batteries every 2 - 3 months. The head unit battery is currently showing 30%.

Negative SRM here for one month. Incompetent manufacturers and/or incompetent techs, and I'm starting to get pretty p'd off.

Ouch! I have a feeling they send everything back to Germany. The potential time taken for warranty work was one of the main reasons I bought a second powertap hub. Having a power meter is addictive!Ant. wrote:Well at least the batteries are CHEAP, and at least you can replace them yourself.

Oh, and 'Happy Birthday" to my first powertap. Between my two wheels, I've clocked up ~ 12,330km in 12 months. My original DT Swiss RR1.2 based wheel became the 'race' wheel, and my 'spare' PT hub was built into a DeepV rim for everyday usage about five months ago. The correction factor the original wheel was 516 and the 'new' wheel was 515 when I checked them the other night. (512 nominal, anything from 500 to 524 is considered normal).
