Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Lots of riders need a bit extra q. Plus you can usually buy shorter axles. So its not a fatal flaw.

I already run short axles, and cleats pushed out. So not for me.

But how difficult would it be to offer replacement axles for the major pedal brands?

Lots of riders need a bit extra q

Ask @xavierdisley about that. It seems that lots of riders would be better off with considerably less Q than standard road cranks provide.

how difficult would it be to offer replaced end axles for the major pedal brands?

Basically impossible for DuraAce, the inner bearing is already right next to the crank. If you can't fix the problem for DuraAce users, you might as well forget about trying for anybody else.

Same with Keo Blade 2, so that's the premier pedals from the two market leaders out.

I wrote a post about it on TT forum then deleted it because Bender Rodriguez was asking and he's a tit. Basically for trained athletes you want to aim for <150mm, from what Limits have said I think it's 15mm each side extra so you're never going to get close to that (ie. using mega low Q cranks you'll bottom out at mid 130s), and it'll push most people out to high 170s with normal cranks, which is definitely bad - not just from an efficiency perspective but also knee tracking/injury potential. We did loads of work on that at a range of Q Factors.

Bike fitters and physios will have a field day with them..

Regarding the Q. I do know People that purposely buy longer axle pedals. But then maybe thats more of a issue With the foot tracking, and a desire not to strike the crankset, then actually wanting high Q.

Regarding the axle thing. I Guess I didnt look into it. I replaced the axles in my last looks, and was thinking of doing the same With some Speedplays. I Guess they could argue that those With top end pedals would buy 'proper'powermeters anyway..........

Further to my post last night: Any interest in my Rotor 3D+ 175mm cranked, 110BCD SRM? Serviced earlier this year, new firmware, battery etc etc, and I have a black PC7 to go with it, alloy handlebar mount etc?

Now in classifieds and shopping, for sale.

Considering that a production model doesn't even exist, nor has even been designed, I'll hold fire for the moment.

It's exactly what happened with Stages, people couldn't see past the prices for the huge limitations on data quality and unit reliability.

I have no clue how, but It is possible on both, on the look's you need a series of tools and patience apparently and the shimano's are just as hard, ti-spindles.com sell them so should be able to tell anyone that wants to know

Speedplay it's super easy to do

Way ahead of you.. "powermeter that isn't available yet versus meters that have been out to market for 10+ years. I'll let you guess which side I'm on."

I have no clue

Sounds about right. Look at the PD-9000 and the Keo Blade 2 and tell me how you're going to fit shorter spindles without completely redesigning the pedals. On some other models, it's obviously feasible, e.g. PD-6800 could probably lose ~10mm

and there's probably ~5mm to be had off the Keo 2 Max

and obviously you could take a good 20mm off the Speedplay Zero, although nobody in their right mind would be using them anyway

Ah right, I though you were just talking about swapping the axles, in hindsight it's obvious you can do that.

although nobody in their right mind would be using them anyway

Just the people who like to know they're cycling, not skiing.

ANyone got a garmin I can borrow for 2 weeks.
Need to return my 1000 for an exchange and don't have a spare!

I've got a 500 I'd be happy to lend you for a couple of weeks. If that's of use, drop me a PM.

My 1000 has been playing up the past week or so. Did your problems coincide with a recent firmware update?

Pedal strike would be a fucker on that Limits one too, I didn't even think of that.

I guess with a bigger q youre more likely to pedal strike. Difficult to strike the actual meter though.

You don't need to if the forces applied are enough to fuck it up.

Why are we still talking about fauxdie vapourware?

Its the same argument against the Garmin pedals. But I cant really see it happening.

Why not? Do you know its tolerances for impact? I'd be interested to see the Vector returns details..

I think it would be pretty hard to strike a Vector pod on anything, and the last time I got pedal strike was mountain biking, so I think from that perspective they are probably ok.

Be interested to see the longevity of mine, track-use only should hopefully not test the bearings and seals etc.

In related news, 38Nm with a pedal spanner is pretty much exactly what I think it is.

I never struck a pod.

so what are peoples views on updating FTP setting based on a real world ride vs a turbo session, my last 20 minute power test was 275 watts, and i averaged 297 for a 10 tonight, should i working to a higher number in training, or should I put that down to pinning a number on being worth 20 watts?

i suspect the right answer (and easier) is the latter, especially as i didn't really believe the 275 number before and have been working to a slightly lower set of targets as a result...

I use the numbers from races on the basis that it's a more accurate reflection of my physiological ability (which is what FTP is supposed to be measuring). It also makes me work a bit harder in training which is always a good thing!

When I do private CP20 tests, I just put my poor performances down to the psychological issue of me being a bit of a wuss.
