They are shocking, Waited nearly three weeks for a shifter, after chasing it up twice, the third call revealed they had cocked up and not even placed the order. A week later the shifter arrived with the thumb shift lever snapped off and super glued back on. I was gob smacked. On the fourth call they said oh sorry, send it back but we have no more in stock and they wouldn’t be ordering any for two weeks. The first time I used them I placed an order and three days later I get an email saying they were out of stock. Utterly useless!
