Happy to build your own?
I know from using them, Mavic A719’s are tough, build up really nicely, and easily run 700 x 32 to 29 x 2.1’s (Mavic rate them for 28mm to 47mm). Not the lightest rims you’ll find tho’ – I will give you that, but I’ve never had to put a spoke key on mine since building them.
(Ok, I know they aren’t 700 x 25, but I guess it depends which end of that scale you favour / how bad you roads are – mine are rubbish so the narrowest road tire I run is 28).
You should be able to get close to ~£200’ish with XT hubs.
More money will get DT Swiss XR331 rims (which look kinda similar’ish).
Good opportunity to consider a dynamo based wheelset (like my Vaya will be getting over the coming months).
