Just what was needed - O-ring

Product was just what was needed to replace missing o-ring. Tiny but important piece to keep brakes running strong.

Good but postage was frustrating

The o-rings fit fine, I had lost one when bleeding my brakes previously and now have a spare so all good. However, the postage price was a bit frustrating. I queried the fact that the postage was £1.99 when they could go in a second class envelope, and was told there is no alternative postal option - seems a bit silly. Won't stop me buying products in the future as I'm impressed by the usability of the website and the customer service.

Hey Harrison, Thanks for the feedback. Our postage rates are set up for Royal Mail Tracked these days and past experience tell us sending small items, such as these o-rings, by any other means just ends up in them getting lost in the system. Many thanks for your feedback.

Had a great experience breeding my brakes with the

The experience was great and though it wasn’t successful the first time because there was residual air in the tube to the back brakes, after advice on chat and a use of bleed funnel it was resolved. I went on to add a disc to my front wheel and repeat the exercise very successfully there on the first attempt!
