Just been to the SRM website and there is now a UCB version - User Changeable Battery using 2 x AA batteries in the BB.

Looks very sensible approach in terms of long battery life and low / protected battery position.

It would be good to know when this will be rolled out to the rest of the SRM line-up - Campag in particular, and how this could work with Ultra-torque.

Using AA batteries in a cycle powermeter is not a sensible approach, I would go as far as to say it is a very stupid design decision!

Weight of 2 x AA batteries, 2 x 23g = 46g

Weight of a CR2032 coin cell 3g ( used in several other powermeters )

Yes the coin cell will run out sooner but we are talking every 6 months instead of every year or two. The AA batteries are also most likely alkaline instead of li-ion in the coin cell.

SRM continue to go backwards whilst, Power2Max, Stages, Garmin, etc move forward.

Does anyone know what combination of SRM and chain rings Astana run? Looks like a specialized SRM spider with Campagnolo Chain rings.

If so, this must be pro only at this stage?

I was playing around with the new SRM last week. The AA battery system doesn't seem as heavy as you might think. If you need the bike UCI-legal anyway, I don't think it will be that big a deal. Actually, it's pretty nicely made. :cry:

Lithum AA at 14.5g each. I'd probably sacrifice 26g to not have to screw with the damn battery so often on the quarq. In a year and a half my quarq went through 4-5 batteries. I know the firmware is supposed to have fixed it...

Might be able to rig up some AAA's too at 7.6g. Though making a spacer sleeve at less than 14g might be difficult.

Monday I visit the headquarter of Pioneer in the Netherlands for a presentation of the Pioneer bike power meter.
Any questions I can ask for you guys?

Will it be compatible with Shimano only or will there be any more versions?

Pioneer is shimano FC 9000 and FC6800 only for now but I`l ask.
I think the go the Stages route by only using alloy cranks.

Although I had heard of the many issues with this unit, it seems those rumors are very true given that Lampre (Rotor sponsored team) have been using Type-S power2max units as of recent...

Weird- the local riders I know that have used it have said its been super problematic regarding drop outs and battery issues. Par for the course with recent SRM problems with their DA9000 units used with non-SRM head units.

Lampre has been using Power2Max for the past few months and its fairly obvious from lots of race pictures.

P2M is working perfect so far...
