Any reason you're not considering pedal based power meter options Roady?
Pedal mechanisms wear out quicker than chainrings. I also have no current requirement to transfer it between bikes... But good call, if they offer me a discount on a set of P1 or P2 then that would also suit with future bike scenario!
i paid 230 for mine. It was used but wear is minimal. all the teeth and the coating are mostly in good shape. the seller included a few spare batteries and mentioend the battery is indeed abit pants. Thanks for all the tips by the way!
I'm putting this on my commuter bike which i do 20 miles per day but i only do 2 days a week on my own bike. I use the TFL (Boris bike) bikes for other days, or take the train if it's too wet. the chainrings should last me decent amount of time. Plus im planning to even the wears between inner and outer ring to maximise the service life lol.
Good price! It is very much 'fit & forget', being very reliable. Something I read said it does it's own zero offsets when coasting but when mine has drifted out I've never been able to get it to self-zero. But then it might be doing it as I've found it so consistent I've only needed to manual-zero every month/6 weeks or so, usually only noticing it with wide temperature shifts (cold mornings & sunny afternoons).
I've ridden mine all weathers and it's really taken some abuse with my commuting (several junctions & stop-start). I would say the FSA rings have worn better than the FSA rings on a Gossamer crankset which came on a Giant Defy 2015. I've kept on top of my chain wear to hopefully prolong chainring life. I've mostly used SRAM PC1130 chains and at £14 a pop I consider them a consumable - regularly changing before they've done 3000 miles. Now my rings are quite worn I've played with the idea of changing them, but they've not got 'bad' enough yet to get a quote for it. I've heard replacement rings cost ~£200 and the calibration can only be done by Powertap service centres when changing them, which I'm guesstimating as costing £50-100. So at the moment I've got a decision on spending £250-300 minimum to get mine working - hopefully within that service cost them being able to diagnose and repair whatever fault mine has.
It's been a great little unit, but at £650 and the ~£200 chainring every 3-4 year cost I would warn people away from them. Dual sided cranks and pedals may cost more initially, but longer term will cost less. A lower cost at £350 new (think that's the deal price Powertap where selling them for directly?) and £200 every 3-4 years they're much more feasible and I would say reliable and accurate enough. Part of me was hoping Powertap would continue to revise them, coming out with a crank spider option where you could use your own rings. Think Quarq pretty much have that nailed now though, so would be tough to compete. With the delay releasing the P2 (and with it really having nothing new) and them never doing a P1S upgrade (as they promised) Powertap have been very quiet the last few years. Also seemingly pulling the C1 from their lineup & considering they're one of the original affordable powermeter companies, they might be struggling. Owned by Saris though (who also own CycleOps) so still one of the main American player in several accessory markets.
Wow that's really good, and you get brakes as well... dammit... I love that blue black fade!
You don't get brakes, just frame, integrated cockpit & seatpost.
Yeah it's Movistar team colours, which I'm not a fan of the team, but the bikes look fantastic!
