An excellent point!
And thus I extend a wholehearted apology to Xanboy. The new wheelset I bought (which is pleasingly shiny and silver, with the added bonus of having a round rear wheel) is the R 561, and they are very similar. Away to my bike shop at the weekend to see if they can rustle up the spokes to bring the original wheel back to the straight and narrow, and to ask them why they didn’t think of this…..
Now what to do with a spare set of wheels?
