Just had another look at the rear wheel and its buckled quite bad so may not even be able to be trued and the spoke replaced. So looks like its a write off, front wheel is fine. Might speak to Planet X tomorrow to see if they can offer anything, though doubt they will as it's nearly a year since I bought them.
Yeah been looking at the Zondas and the reviews look very good - seem ideal for my cycling, so definitely considering them - just the price seems a little ouch to me at present. With the Planet X AL30s how long did you have them before returning them for a full refund? Mine have been about a year so doubt I can return them.
I'd say it's unlikely Planet X will offer anything. I had mine nearly 3 months but the spokes all went in quick succession to the point I had zero confidence in them any more. I'd done 1200 miles on them according to Strava and were great wheels until they started breaking.
I initially replaced them with Fulcrum Racing 5s last summer and they've been bombproof. Saw me through the whole of last summer, autumn and winter without a single issue and I'm still riding to work on them and using them on the winter bike for soggy rides. If you don't want to stretch to Zondas, maybe consider them instead? The Zondas are lovely though and a bit of a bargain.
