Subject: PowerTap SL and TrainerRoad?
Hey all-- a buddy wants to sell me his PowerTap SL for what seems to be a ridiculously low price. As I'm looking at it, though, it looks like this is a wired system, so I can't hook it up to ANT/TrainerRoad, etc., correct?

Also, he's selling it with a pair of race wheels, which would be nice, but I don't want to train on the race wheels full-time-- how much of a pain is it to pull the hub out and put it in other wheels? For example, could I pull it out of the race wheels and drop it in my normal trainer setup, then drop it back in the race wheels whenever I have a race?

Thanks!

TrainerRoad works with ANT+ devices. I don't know about the interface on a PT SL, but if it's wired only, you somehow need to get that power signal into ANT+ wireless format.

A hacker could probably pull this off, but it could take some work.

Here's TrainerRoads page on required hardware:

If its a wired PowerTap, then no I don't believe it will work with TrainerRoad because its not ANT+. That is a wireless technology if I understand it correctly.

As far as "pulling out the hubs and dropping them back in for races", this is not really a possibility. Lacing up a hub into a wheel is a pretty big job, not like just swapping out a cassette or something. In my opinion it would be a huge PITA to take the PT hub out of the race wheels and put it into a trainer wheel, only to put it back into the race wheel at a later date.

An easier method (and likely just as fast or faster) would be to leave the PT hub in your trainer wheel, like a Mavic Open Pro or something, and then use an Aerojacket wheel cover from Wheel Builder. Those are only $100 and you can take them off/on for races really easily. And they are 95% as aero as a $2000 disc wheel.

Good luck.

Dave-- if I'm getting you correctly, you're saying put the wheel cover on the trainer wheel for races? Thanks--

Yes. That's what I do (and a lot of other folks to from what I've read and seen). Works great and it is a really fast wheel.

If he's selling you an older 'wired' Powertap, they don't really have a lot of value these days.  $100 maybe?  "ridiculously cheap" to me for a wired PT would be 'free'.  Plus, given that it won't talk to anything but the LYC (Cyclops' little yellow computer), it precludes you from having a GPS computer... well, unless you have two computers with you.  And, as stated above, if it's a wired system, it won't work with TrainerRoad.  Then again- the whole point of Trainer Road is that it creates a virtual power based on your trainer- so you can ride virtual power without a powertap, just using the $40 GSC-10 speed cadence sensor.

Plus, it's probably old, well used and might need new bearings and a rebuild anyway.  It would cost you a couple hundred bucks to have a wheel built around it- at which point you'd have an old wired powertap in a new wheel.  Something that almost nobody wants.

If you want a powertap... save your money and get one.  a good one.

I agree with most of the above but want to add that Saris is dropping support for the wired units so if the unit fails, it's done. They will upgrade the internals to ANT+ or replace the whole wheel at a discounted rate if the upgrade is not possible. The GSC-10 option is a better one IMHO for Trainer Road until you are ready to get an ANT+ powermeter
