Triathlon nut.
GB Age group team, Sprint distance.
Ride 20 miles each way to work throughout the year.
Using a Planet X Cross bike on road tyres which gives decent brakes even in winter and only a slight weight penalty (and I'm commuting so who cares about 500g or whatever).
Currently injured after falling off my Mtb and busting a few ribs but managed 10m yesterday,
though the bumps were a bit sore,,,,,
I'd suggest join a cycle club if you haven't already, you'll be surprised at just how many people will be prepared to discuss gear ratios etc for hours on end without pausing for breath. As a newly (self) diagnosed Aspie I think the real numbers of ASD in the popultiona are far, far higher than the 1:100 commonly quoted.
More than happy to discuss gear ratios or whatever myself!!
