Bought a 700 x 35c Vittoria Randonneur Cross from wiggle.co.uk.
The inside circumference was so short to the point of damaging the rim fitting it with steel levers. Pinched tubes etc, No way to risk this performance if you get a flat while commuting.
I emailed Wiggle customer service.
They took it back for an immediate full refund and postage.
Their prices are great. And customer service like this proves they stand behind what they sell. Which in this day and age of busted out banks and guarantees not worth the paper they're written on is something.
