FAO Super & his encyclopedic brain! 29" wheel weight

bails87

I'm thinking of building wheels for my (sshhhhh!) CX bike on some Mavic TN317 rims.

The rims are 540g each, I'd probably do it on XT (6 bolt) hubs which have a combined weight of just over 500g (?) and wondered if someone/Supersonic had an idea of the spoke weights that would be added to that? Based on some rough speculation, the spokes would be about 290mm. (Obviously, I would figure it out properly before uilding the wheels, if I even do it. I just want a rough estimate on 'standard' DB spokes, so I can work out if they'd be any better than the stock wheels)

Happy for someone to suggest better (narrow, 17mm) 29" rims btw.

You called? ;-)

64 x DT Comp 2.0/1.8/2.0 double butted spokes at 260mm weigh 380g. So 290mm is going to weigh about 420-430g.

As for rims the TN719 is lighter and uses a tougher alloy, but costs more. If you want light weight, then the Open Pro.

Ta very much.

Including nipples that puts them just under 2.1kg.

Or, just over 2kg with TN719s.

The Open Pros might be too narrow, as I'd want to be able to put 35mm ice spikes on them.

I'll have to weigh my current ones, to see how they measure up, or just wait for someone to start making CX disc wheels!

Thanks again.

Cheers, but 27mm :shock: That's wider than the tyres that'll be on them!
