New rim for my PT

mclarent

I'm thinking about replacing my PT Elite+ rim. Have a DT swiss rim on there at the moment, cosmetically fine but it's never run true since I got it, and the wheel is too heavy for racing. Any suggestions what to replace it with? I want something strong enough for winter training, but aero and light enough for RR'ing - am I dreaming???

IRD Cadence Aero?

I just use an Open pro for training, racing and TTing (with a disc cover).

Yeah, had no problems with prior Open Pro wheelsets, just wonder if there's another option. I hadn't thought about the IRDs, have you ridden them? I usually ride racing 3s, which are lighter and spin up really nicely, which always leaves me making negative comparisons...

What DT swiss rim have you got on there? How many spokes is the hub drilled for?
If the wheel's not true, then that's the builder's fault becuase DT rims are extremely high quality and build up very nicely (have just built one myself!). The cheap way to resolve your problem might simply be to rebuild the wheel.

PT hubs are heavy, this is never going to be a light wheel, but it you want fast spin up, look at the rim weight. Also, aero on the rear wheel is not that beneficial. The only reason to chose a deep section rim on a rear PT build is if the spoke count is low, otherwise go for a decent box section rim (DT RR465, Open Pro, Excellight).

For light you want the Cadence at 390g. Light-ish plus aero then the Cadence Aero at 465g.

But as huuregeil says its never going to be a light wheel, especially with an Elite+ hub.

What about the stans alpha 340 coming in at 350g?

TBH, I just want a dependable wheel on the rear, even for racing, hence a 32spoke Open Pro. At my level and weight/size I don't think a hundred grams of spoke and rim extra are going to make that much difference to me... I had a Zipp 808 rear which I sold because I always used my PT!

It's a DT RR465 IIRC, can't remember spoke count but it will be 32 or 36 I'd guess. And yeah, I'm blaming the builder for sure(!) It was online from a very well known supplier, I actually ordered an Open Pro got delivered a DT Swiss and the build quality was poor. "Knowing what I know now"...

Part of it is due to the fact I want to get my front training wheel rebuilt as well - I'm currently running an OP rim on an oldish silver 105 hub (which quite matches my PT hub), and the rim needs replacing. However, given the problems I've had with the DT rim I just don't trust it anymore (may not reflect the rim quality, I can't comment on that tbh!).

I need the new wheelset to be strong enough to survive winter training (next year!), but want to minimise the impact of the heavy PT hub as much as possible, so I thought deeper section (more aero) would be better than lighter rim? I'm around 80kgs, so rim strength is not a major issue apart from dealing with crappy road conditions. Cost is not the major constraining factor(!)

Personally, I'd just rebuild the wheel (using new spokes and a decent builder!), assuming the rim has never really been seriously whanged out of true. RR465 32h on a PT hub will be plenty strong if built up correctly. The aero benefits of a 30mm rim on a rear wheel are negligible. The real advantage of a deep section rim on the back comes when you can drop the spoke count (which you can't, unless you want to fork out for a new pt :-) ) and still end up with a stiff and strong wheel at a relatively light weight.
