What would it cost me to get my current Zipp 404 rim built up with an existing powertap? There are some great deals out there on powertaps, so I’d like to finally start riding with power. I have a Garmin Edge 500 and the 404. So, if I get the powertap, what would I expect to pay to get this built up with the 404?
I had a PT in an older HED Alps that I had wheelbuilder rebuild as a non-PT Alps and then take the PT hub and build a strong training wheel. Both have held up well so I’d call Rich at wheelbuilder and ask…
I was never a fan of training on a race wheel…so why not get a Quarq or SRM and just keep the 404…and use the Edge 500…

I don’t either, but I like the shape of the 404 with a cover.
SRMs are pricey. What could I expect to pay for a Quarq? I would have to change the cranks to be able to move it around, however. I’d want to change the BBs and cranks on both, if I did this. My road bike came with compacts on an ISIS BB and my tri bike was purchased used with a standard 53/39 Shimano crank with Octalink. The Powertap gets around this…I think. ???
All the ways have downsides…
I’m too lazy and time-limited to swap things but a wireless PT wheel would be the easiest way to go for 2 bikes (for me). I wouldn’t want to swap a crank back and forth but people say it’s just as easy and a 10 minute job. If you already have the computer - I think a Quarq or cheapest SRM (I bought a Gossamer without the computer for about the price of a Quarq without the computer…) would run you about $2000 by the time all is said and done I think (maybe a tad cheaper). Bottom brackets are cheap but you would need 2 new ones…plus you’d have to ride the same front chainrings on both bikes. My Gossamer is a 130 outer/110 inner and I do have alternate rings so I could run a 53/38 or a 50/34 I believe but then you worry that changing chainrings changes how the PM reads…
If you train/race with the 404 PT- you’d have to swap tires/tubes for races plus worry about beating up a race wheel with training - plus deal with a cover. This is probably the simpler/better option though…
I do have a wired PT on my road bike which works fine and a wireless SRM on my tri bike that works fine…but I like the Garmin computer much better than the little yellow PT computer. I also like wireless much better…

Thanks, Dave.
At some point I am going to change the Tri bike to a compact and that might simplify things for a Quarq. All of those things are true, and I’d have to swap tires for my trainer, too, because I don’t have a computrainer. Makes for tough choices. Ugh!
A 404 would not be hard to build with a PT. Probably any decent bike shop could do it.
My guess would be near $50 plus spokes. Spokes could be anywhere from $30 to $100 depending on what spokes you choose.

Thanks for the info.
I thought the pedal based PMs would be cheaper, but it doesn’t appear so.
Of course, I think I probably pedal harder with my right leg, which would likely throw off the measurements on those.
$100-$200 for spokes+labor. I’m amazed how variable the cost is at different shops, so get quotes.
Note: Building up a PT hub is no harder than building a standard one.
This.
Dick,
Since you are in the area, I would suggest going in and talking to Win at Wins Wheels.
He can point you in the right direction and answer whatever questions you have regarding how much to do any number of things…like building a PT into a wheel and what they would charge to do that. BTW, I swapped Quarqs between two bikes and it was super simple…then, since my Shiv came with different length cranks and different TT chain rings, I just have two Quarqs now…that’s the easiest solution.
Thanks. That helps.

In my dreams. My wife will have a cow about any PM. Two Quarqs…I’d be sleeping in the garage.
I’ll look into Wins
