Anyone running SRMs Amateur model ? What are they like ? Do you run them with a disc rear wheel ? Do you race on them ?
Yes.
Fantastic product. No need to spend more on the pro model unless you really want to - this version works perfectly.
I race with a disk. Use any wheelset you like, the SRM is in the crank. Get the front wheel speed sensor if you plan to use a disk.
As reported last year in MSSE, the SRMs aren’t always ‘great’ and can have issues with them. most notably many of them come poorly calibrated from the factory and can drift over time.
i would always recommend calibrating them prior to use (this is mentioned on the SRM site to).

The SRM don’t come calibrated but it takes all of 30 seconds to do…no big deal.
I have had no issues with mine. IMO it’s a better solution then the Power-Tap.
Yeah I heard that callibration can be a real pain. Like if you switch BBs, you must redo it. Seems like a rather touchy system that could require alot of time to get set up properly. Could be a problem if you’re switching to lighter race cranks then having to recalibrate them every week when you go back to training. My Powertap Pro works just fine for me…
I don’t have SRM or powertap, but are you saying you have race cranks? I don’t think I’ve ever heard of that before. What are your training cranks?

that wasn’t my point (that it was better or worse than a PT), i was responding to your previous post about how great the SRM is. I was therefore clarifying that it requires calibration and that the Amateur units can drift over time.

I’m saying that people may not want to race on SRMs because of the added weight. This doesn’t matter so much for TTs, but road racers would probably opt to switch over to Dura Ace/Carbon something instead of SRMs. And yes I know that Pros race on SRMs but that seems to be an early season thing. When the big races come they’re always on lighter, “regular” cranks. Basically its a weight thing.
SRM cranks used for training and racing.
The reason for switching between bikes was to have power whenever I rode.
if you give one point only, say x=0, y=0, how many lines can go through that point?
answer: an infinity…so when you think you calibrate your srm, all you do is making sure that when applying for force, it reads: 0w, but you still haven’t calibrated them…
