Hey Andy 48 x 14 is a big gear for preston park! I have never been above 47 x 14 there and usualy use 46 x 14
thanks for the advice! i did a few calculations - i only have a 53 and a 48 chainring, so i reckon i'll give 53 x 16 a go. it's an 89. i'm not a fast twicther, but i can push a gear, so that could work out... i'll find out i guess. the 53 isn't track specific, just hope the chainline is OK; should still work shouldn't it??
