We don't charge VAT, however, if buying from outside of the UK please remember that there may be import fees to pay directly to the delivery company before receiving the order.

Back Shape - most adjustable stops have curved backs, designed to fit steel frames with standard braze-ons and a down tube diameter of around 28.6 mm (1 1/8"). Some oversized frames have flat plates at the base, these require stops with flat backs.

Boss Thread Size - most frames will have M5 (5mm) threads on the shifter bosses as this has been standard for a long time. However, if you're converting an older frame with Shimano bosses (M4.5 / 4.5 mm threads) or French bosses (5 x 1 mm threads) you'll need to use different bolts to fix the adjusters to your frame.
