Hi-
My XTC came with a pair of 36H CR18s, which aren't all that heavy for a tough rim (440g).
But with my weight, light load and riding (commuting as unfortunately didn't get a chance for a laden getaway yet) a lighter wheel can be safely used.
I believe Mavic XC517 were the lightest option Thorn offered.
However, XC517s are not being made anymore. You see used wheels on "fleabay" and I am keeping an eye out there.
Are there any other common lightweight 26" wheels that are easy to find secondhand and that are reliable?
(I can get an Alexrim etc, but I know Thorn picks their parts for a reason)
:)

mavic 717 rim brake in 32 holes = 420g, 517 = 410g. I build a few 717 rim brake wheels every year for fast light commuting/touring duties, never any bother 32holes are fine built onto quality hubs and with double butted spokes. On my own RST, it came with sun cr18s, one of the most disapointing and short lived rims I have used, I went for rigida carbide coated a few years back; heavier but ok for the commute duty, audax, fast touring use.
Happy to advise on build specifics and help you out further :)

I got the bike secondhand with CR18 and no bother myself. However, it depends on loading too I am light and I don't carry much on commute either.
A 717 is 20 grams lighter, you really notice that difference as much compared to CR18? :)
Of course a tourer isn't a racing machine, just wondering...
Had a look at your site, sounds like great fun to do. We have some bike shops and a shared workshop here, the longest running shop closed it's doors unfortunately...
-
I would not imagine the 20g difference would have much effect. Maybe some Schwalbe Kojak 1.3 tyres would be a better investment depending on what tyres you are currently running?

Thanks for that dave will pm you .

Hi Jags, thanks! Look lovely but guy won't post per ad.
-
do you want me to try and contact him, i had a chat with him before nice guy but not to keen to travel .
look to be a good set of wheels though.
-
I got a wheelbox I can post him, but didn't get chance into looking into that yet, as than total cost might be higher than getting parts and building wheel myself.
They do look lovely though, classy!
You can ask the question though if you want, if it's NOOOOOOOOOOOOO! even when he doesn't have to find a box then that's sorted.
Tx :)

no bother i'll email him now see what he says.

apologies to davefife on the new front wheel saga.. i was getting Dave to build it for me but my good wife bought me the shimano one for Christmas.
