NOT Ultegra brake callipers.
Wiggle states they had 10+ of each. Waited over a week to find they were put on back order, but it turns out they couldn't get them and didn't think to tell me or refund me.
Website said 10+ all weekend before they finally resolved their issue. No apology or offer of discount off another product.
Missed the cheaper price with another supplier too.
Only posting, as saw a thread saying
Tredz are bad for doing this. Well it turns out that they're not alone!
