SS for the road ratio question?
42:16 is pretty normal for a fixed – about 68″. You are a little lower but this shouldn’t hold you back as you can coast downhill. Chain deflection should be less than half an inch vertically at the tightest point (chainrings aren’t round. Looks like you have a golden ratio.Posted 6 years agoElfinsafetyMember
Pends dunnit. Higher gearing for high-pressure skinny tyres, lower for fatter tyred commuting and urban riding. I use a 38/16t combo here with 50-60psi 700/35c tyres in That London, and find it just spot on for riding in slow traffic, along towpaths and for when I’m laden with shopping, but it is a little bit low for longer road-riding. Spins out at about 18-20mph really, although most of the time I’m riding around at about 12-14 mph. Gets me up Highgate and Hampstead climbs easily enough though, and the acceleration’s good for getting out of the way of trouble in heavy traffic. If I take the rack and paraphernalia off, the bike’s a good bit lighter and could go to a 40 or 42/16t, but I also want to be able to ride home slowly from the pub when I’m knackered. 🙂
Find what’s comfortable for you, and your riding style, then stick with it.Posted 6 years ago
It looks like I’m now going to have a SS road bike after destroying the rear mech, the chain and a bit of the cassette, basically making the bike an economic write off.
A roadside bodge got the chain back on and at 39:16 seemed like a reasonable ratio. Thoughts on ratios? It currently runs a 39/53.
I assume chain line is not an issue.
No tensioner or means of tensioning as vertical dropouts and goosed hanger. The chain is quite tight so I assume not an issue.
39:16 good or not for North Shrops/Cheshire/(bit of)N. Wales?Posted 6 years agoMrSalmonMember
45:16 in West Mids. Good on the whole but there are a few small hills where it feels like I’m doing about 15 rpm.
At the risk of stating the obvious though, it’s up to you to decide where you want to compromise. 45:18 was far to spinny for me on the flat. 42:16 was alright but any sort of downhill and you spin out very quickly.Posted 6 years ago
