Haha just contemplating the same, struggling to find confirmed weights though. I’m about 82kg and will prob only go 28 on the front, plus I’d probably just stick on me 29er trail wheels for anything fun!!.
Was looking at cheap Mavic a119s but thought if the DT’s are as per the advertised wieght it might be worth a punt to save nearly 100g a rim.
Do they do the DT rims in a 26er size do you know?. Winstanleys seem to advertise the 29er version for about £22 and a non-sized (presumably 26er) version at £19.99. Just not sure if the cheaper ones would be 26 or 29″.
Fatbirds is cheaper again at £18.99 but then they charge postage under £50 so not really cheaper.
