C1 Chainrings going bye bye?

Someone told me the current sale is because the product is being phased out. I love them and find them a good solution for riders need a power meter solution when going under 165mm on cranks.

Can anyone confirm or deny?

Nothing to add other than I’ve been happy with mine. Based on the current 50% discount to the price I bought it, I wouldn’t be surprised if the rumor you heard was true.

If you are looking for more hearsay, someone told me that PowerTap is phasing out both the C1 AND the P1’s and focusing on hubs. I don’t know if there is any validity to that or if it just a rumor. I am hoping the latter, but watching this thread hoping something credible comes up.

Thanks for this. At that price I’m in:)

Yeah it’s pretty badass. You can do a Cobb short arm “crank based” power meter for less than 650.

Purchased both the C1 chainrings on sale and the Cobb Cranks (alloy) on sale. Unfortunately, the C1 chainrings did not fit on the Cobb cranks despite what PowerTap indicates on their website. It’s kind of strange since PowerTap indicates they tested with a Cobb crank physically in hand. The rings won’t lay flat because they hit part of the crank in the attached photo.

I ended up buying a short Sram Apex crankset (10 speed) from http://bikesmithdesign.com. The C1’s fit on that fine.

The chain ring selection has made me dismiss these, but for the price I might buy one anyway.

They probably took a hit in the pedal market when the prices dropped last year, and they own the hub market.

IMO power meter pricing has another $200 or so to fall. If they concentrate on the hub market and do a couple of OEM deals, PMs could become standard equipment on new bikes very soon. That would put some pressure on the crank-mounted guys to get down to $199 where they will eventually end up.

I’d love an updated disk brake hub.

Now that FSA has followed Shimano to 4-bolt (and, on some of their newest stuff, direct mount) chainrings, very few new bikes are coming with cranksets that are compatible with the 5 bolt C1’s.

That’s weird because I have seen the C1 on numerous Cobb cranks.

The C1 definitely fits on Cobb cranks. At least the alloy ones. I haven’t installed them on the carbon’s yet.

Doesn’t fit on BBright frames, like Cervelos.

In my case they didn’t fit. It was very close to fitting, but the center hole of the rings hit the chainring support arms. It wouldn’t lay flat but would rock as I tried to get it to line up.

The hub market will be interesting because the switch to disc brakes will make a lot of PTs obsolete. I currently have 4 PTs in various wheels and if I made the jump to disc on the road and TT bike I would really consider moving to crank-based power.

Someone really needs to make a series of short cranks that are Quarq Prime capable. They also need to have a hot design. Cobb stuff is just so ugly.

I can’t confirm or deny it being phased out, but I think retiring this iteration of the C1 would be a good thing for Powertap. They’re a great company overall, and have top-notch customer service, but I feel this version is/was a dud. I had 2 units fail 3 times due to water ingress issues, direct from the factory. Compound that with the battery life issues, and incompatibility with the newest SRAM and Shimano cranksets, I feel it’s time for a reboot. Maybe time for a C2, or just retire this product line to focus on the hubs and pedals.

It fits on my S3 with BBright just fine with a FSA SLK Light 386 EVO crankset.

Confirmed.

Nice! PT says on their site that C1’s won’t fit on BBright frames so I’d crossed them off my list.
