If you’re happy with cup and cone bearings these should be OK
They’re £210, £100 is just the front.
IME the shimano factory wheels are fine, the Planet-X wheels have really light hubs, the rims are light but nothing special. The shimano wheels have quite heavy hubs, so feel a lot lighter when accelerating than they are. Theres a difference between my cheap shimano wheels and my 1250g Stans wheelset, but it’s not as noticeable as the jump between the shimano’s and the Mavic CXP rimed wheels they replaced.
RS11 – cheap, not too heavy, good workhorse wheelset
RS31 – RS11’s with deeper rims, create their own gravitational field once spinning.
RS61 – Like RS11’s, but better allround, tubeless compatible, cost more.
RS501 – like RS11’s, but with normal spokes and hubs.
I’d get RS11’s unless you particulalry want the RS61’s, the 501’s aren’t much cheaper, and the 31’s are just pointless unless you’re TT’ing on a very flat course and have no money.
