Wilfred - Your probably right, im not 100% sure, however, when setting the low limit, it shifts the dr outwards - this ultimately affects how far across the dr will go, or am I incorrect?
wphamilton - If I loosen all the screws then the dr's positioning is pulled right in close to the frame and therefore, the shifter cannot pull it far enough across to reach the big ring - Should I then adjust the cable tension?
Thanks
