im sure i read this on here somewhere. where can you order groupsets from that gives good discounts, are reliable and have no import duty? somewhere in germany?
have a look at actionsports and bike24.
www.actionsports.de are very good - postage is cheap and stuff turns up fate. I've not tried http://www.rczbikeshop.com/anglais/ but the prices look good.
bike-components.de are the cheapest I've seen - 199 EUR for SLX gearing group at one point (Shifters, derailleurs, chain & cassette)
A mate got a 10 speed XT groupset from Germany - either bike-components.de or actionsports for a great price. It arrived quicker than other items he'd ordered from UK mail order retailers at the same time.
