Power2max/Quarq Riken

I'm currently considering buying a crank based power meter in preference to a powertap and I have been aware of the Power2max unit for a while now and I am happy to see they addressed the early reported issues with drift through temperature changes.
The thing is they now no longer support GXP systems as they no longer supply with any SRAM cranks and this is a little problem as all my bikes are GXP... I have the option of buying the Rotor cranks with Power2max (I run 2 Hope BB's on 2 of my bikes with the conversion shims for GXP so could easily convert one or both back) or hold out to see if an older SRAM S900 appears second hand but they seem to be a little like hens teeth...
The other option I have is to buy the new Quarq Riken which is quite a bit more expensive but saves me any hassle with BB compatibility. Has any one been using a Riken considering they are new?
Really just trying to work out whether a Riken is worth the extra expense just to limit the hassle of swapping the crank between bikes or if I shouldn't be so lazy and just adapt my BB's on the bikes it'll be used with and buy the Rotor...

Probably makes more sense to get a powertap0

You can buy new old-style S900 cranks on eBay from a seller in the USA. If you search 'Wickwerks' you'll find them. Here's one of them. Rebranded, but they are just S900 cranksets.
Also, do you know that the Truvativ Rouleur carbon and the Bontrager Race X Light are the same as the old S900?More problems but still living....0 -
Thanks for the link.
I did note the other cranks on the power2max website as other alternatives but having done a quick search they appeared to be just as hard to find. Maybe my Googling isn't up to much!
I'll have look at the link, although I may just go with the Rotor cranks if all else fails and accept the hassle of swapping it between bikes as another BB in addition to the cranks still comes in cheaper than a Riken...0 -
It took me a good few weeks to find one last year. I plastered forums with wanted ads (which didn't lead to anything) and searched eBay a lot. I got a Truvativ Rouleur carbon on eBay eventually.
I think this is the right Bontrager crank.More problems but still living....0 -
Again thanks!
I've contacted the seller about whether it has a removable spider and what year it is. I'll keep an eye on it and I must try harder with Google/ebay!!
A quick calc shows a wickwerks chainset and powermeter is about the same cost as the Rotor cranks from Power2max. And I can estimate duty/VAT if I choose that option as no doubt it'll be added since they are shipped from the states.0 -
Hi
I've just bought a Riken. One of the reasons was that I got an R5 on the half price deal last year. The BB-Right was a bit of a pain really, trying to find a crankset that I liked which didn't totally break the bank. I was determined not to ride with adapters so I took the plunge on a Quarq.
I got a good deal on a pre order and got it on release day. Also the idea of training with power was something i'd been interested in for some time.
Changing the rings with no re calibration is a really nice touch, setup was very easy and I'm more than happy so far.
I haven't had long enough for a proper review but heres some real pictures http://ramblingsofanamateurcyclist.blog ... riken.html
I hope this helps in some way for you.0 -
I brought an S975 Quarq middle last year, I have had a few issues with it, it's been returned a couple of times, and the latest time the spider has been replaced with a Riken spider under warranty.
First impressions are good, on the face of it, it seems a much better unit than the S975, but time will tell, hopefully they've learnt lessons from the issues the earlier ones had.0 -
As danowat says the Riken is a much better unit than the previous S975 version, they've completely redesigned the spider to increase stiffness and moved the electronics into a much more durable housing.
A GXP version of this is easy to swap between bikes - and great value at £1250 compared to some of the other options out there.0 -
