Good day all! I have recently purchased some Excel wheels (second hand) which have come with a rear sprocket that contains only 42 teeth - with these the blokey gave me some enduro wheels as well with a sprocket with 41 teeth on it. The problem is that my bike is completely stock (apart from the uncorking i have done gained from info from this great place) - so my rear wheel has a sprocket with 49 teeth on it. Now, after changing the wheels (to get it legal for the road so it passes its MOT) the chain is obviously too loose. What would be the best thing to do in this situation - as if i take links out my chain i will be limited to the smaller rear sprocket which changes the gearing of the bike for a higher top end and so sacraficing my low end torque when going off road. Will the smaller rear sprocket affect the off road performance of the bike so taht I would notice (I plod along off road - I am no demon off-roader). Thanks ice.
