Powertap Pro - Alloy Rear Wheel

Does anyone know the spec of the rim used on the Powertap Pro Alloy Rear Wheel's?

Powertap Pro - Alloy Rear Wheel
http://www.cycleops.com/fr/produits/wat ... gory_id=21

Here are the specs that I can find on their website:
Weight: 1150g
Hub: CycleOps (446g)
Depth: 45mm & Width: 21.6mm
Spoke: DT Swiss Aerolite, Spoke Count: 24 & Spoke Pattern: 2X (or maybe DT Swiss Competition spokes - 3x spoke pattern??)

We pair our PowerTap G3 or Pro hubs with our 32-spoke, V-shaped rims, DT Swiss Competition spokes, and brass nipples to offer you day in and day out reliability coupled with the precision of power measurement.

I currently have a pair of Fulcrum R3's which I've been very happy with; the rear R3 is quoted as 915g.
So the Powertap Pro rear is 235g heavier, and I assume the majority of the weight is the powertap hub?

I guess this is leading to the question of an "off the shelf powertap" vs 'custom wheel build". And I assume this is a clincher?

Not many (or any) reviews out there for the Powertap Pro Alloy Rear Wheel's (or wheelsets), but Wiggle have the rear for ~£610 (including extra 10% for Gold Members at the moment) - which seems a bit of a bargain (relatively obviously!)

Thanks. Looks like a good solid rim and ideal for the Powertap.

I swapped mine out for a Mavic open pro.

Sorry to bother you.. but a genuinely interested question.. (I have one ordered BTW, £607 from Wiggle!)

I was looking at the weight reduction:

RR465: 465g vs OpenPro: 435g
465 - 435 = 30g difference.

And lighter spokes....
DT aerolite (139g) vs DT competition (191g) [based on 32 spokes per wheel]
191 - 139 = 52g

But it seems the weight reduction of the G3 (£850) rather than the 100g heavier Pro (£607) is not easily (and cheaply) reduced by upgrading the rim/spokes.

What was the main reason for swapping out the rim?

Not that I'm already planning an upgrade, but thinking that in the future maybe this new wheel gets turned into an aero wheel, where overall weight is less of an issue compared to it being more aero. So interested in your thoughts.

I have no experience with DT rims, either Road or MTB, so this is a bit an unknown.

DT 465 is an excellent rim, the best road rim DT makes.
I have recently built a wheel on the PT PRO with an Ambrosio Excellight and 32 ACI DB spokes... it came at 1080 grams

The main reason I changed was down to how bloody hard it was to changeout a tyre on the dt Swiss.with changing between turbo tyre and normal tyre all the time this became frustrating.i
I can change tyres on mavic rims by hand it's so easy

In a scale of easiness, Ambrosio rims are the easiest to change a tyre, followed by the Mavic and then the DT... none of them is anywhere near a nightmare as it's the case for some Campagnolo rims! During a club ride it took 6 hands with levers to replace a tyre on a Scirocco wheel!

Thanks for that tip ugo.

Thanks. Sounds like the rim is OK apart from fitting tyres... so will see how it compares to the Fulcrum R3's in terms of fitting tyres (are these classed as Compag wheels?)

The 465 are actually OK... it's not a terrible battle, but it requires levers, while Ambrosio can be fitted manually... Fulcrums are not as bad as Campagnolo... BTW, apparently the newer Campagnolo have a better bridge geometry which makes the job easier, if you believe brochures

Powertap arrived (managed to get it for £596 delivered) and now fitted.

Tyres (Conti GP) are actally easier to fit to the 465 rather than the Fulcrum rims, so looking good. It was noticeable the extra weight of the wheel, but I don't think I'll actually notice it riding TBH.
