I have two questions concerning cross-equipment.
The first concerns Ritchey tires. I live in the UK and I have been desperately trying to source the following models:
1. Z.E.D. 700C (700x42)
2. Speedmax Cross (700x30)
3. Excavader 700 (700x35)
Does anybody know of any shop (in the UK, preferably in the London area)or e-store that carries or is able to order these tires.
My second question concerns chainrings for the Ultegra triple. The standard set up is 52/42/30. I have been running this set up for a little over a year. But, I am now considering changing this ratio to 48/39/30. Has anybody out there tried this type of set up. or, do you know if the 48/39 are compatible with the Ultegra triple cranks.
Thanks for your help.
Take care
