I've been on my SS (65") since xmas. I find that it gives a better workout for less time. Also easier on the maintenance side.
Hardly ever ride in groups now and as I am retired, don't need to go out on wet days, so no mudguards for me.
And lights on all year round.
With my first club, we only had winter runs, starting on the 1st Sunday in October and ran through to the beginning of March when the TT season used to start. The Larkhill Wh's 2-up sticks in my minds as being one of the first events each year.
May get my winter
Ribble (gears) out soon, as I want to start finding some of the local Kentish mountains.
