My first go at SSing about 15 years ago didn’t last very long as I found it frustrating on the road sections between the rather thinly spread bridleways. It was fun off road though.
Having moved to the Surrey Hills/North Downs, I can ride from my front door for hours only crossing the odd bit of tarmac. I bought a cheap old SS Inbred off here a year and a half ago and love it.
I do seam to fly in the face of convension however and put an Alfine on for the winter (where it appears lots go from gears to SS for winter) as on the steeper hills that you have to attack, out of the saddle and give it full beans find I loose traction.
I also find it can be a bit anti-social if riding with friend on geared bikes as you have to ride at your own pace, so miss out on the conversations you have sitting and spinning up the long climbs.
