Powertap or Pro

vitiris

I am glad to hear that my Tacx may be under-reading as trying to do 4 intervals generating 260W was killing me! Especially as a friend of mine with an elite was laying claim to 300W for 40 mins. Anyway I am toying with the idea of buying a Powertap and have seen that Bikeworld.com are selling the Bontrager wheel at $999.99 which given the Dollar's weakness against Sterling at present seems a good deal. My question is what is the difference between the Pro and standard and which would you recommend?

Any advice greatly appreciated
Sean

i have ridden both and for some reason i have horrible luck with Powertap. sand or other junk gets in the hub bearings and cassette body. right now my hub makes this noise every time i spin it. hopefully it doesn't get worse, i can still ride it right now.
i am getting sick of bringing these powertap hubs to the bike shop to get rebuilt.
i haven't heard of anyone else having problems like this, why me!!?!!?!
maybe i ride too hard. but i don't abuse my equipment.

my next powermeter is going to be a SRM, if i can afford it someday.

I'd hold out if I were you. SRM has it's fair share of problems too. Plus, even when it's working perfectly it needs an awful lot of attention to stay calibrated.

I suspect that within a year or two there will be some new devices which force the quality of all of the divices to rise.

If I had enough money lying around I'd even try to develop my idea for a PM.

vitiris - the Pro has a separate wiring harness & pickup for cadence. The Std infers the cadence from some other measurement(s). One is led to belive that the Pro thus records a more accurate cadence.
I think only the Pro has the interval feature. I find this very valuable while doing intervals.
The Graber/PT website may have the PT manual on line. The Std & Pro use the same manual, different sections for the two models.
Training is unique to each racer, thus the tools & one's use of the tools is also unique. Some may find the Std adequate. I think the Pro is terrific & have had no serious problems with it.
