Another update! In an earlier post I mentioned replacing the 52 tooth chainwheel with a 48. I was pretty happy with the lower gearing but a recent ride showed that even lower gearing would be better!. I now have a 46 tooth chainwheel allied to a 11-32 cassette and this is proving to be even better. I shall be working 6 days a week until Christmas (and possibly beyond) and have Grandad and church duties to perform too so riding time will be tight. A quick ride today showed all was well but as my fitness levels will suffer because of lack of saddle time the lower gears will be very welcome!
