- Single Speed ratio for full sus
Put to use my old Stumpy full sus by kitting it out as a Single Speeder but not sure what size front chairing to use biased slightly to climbing also will need some sort of tensioner for rear to accommodate changing chain length (because of rear movement).
Should I have done this in the first place to a full susser or traded for HT?Posted 8 years ago
you’ll probably be best with a bodged derailleur for chain tension – not sure most tensioners will cope with the chain length changes very well.
it’s easier to SS a URT suspension bike but you coudl give it a go.
Or maybe just switch it to 1×9 or whatever and keep the rear gears?
as for front chainring – use the 32 off the existing chainset and then an 18 at the bake to give yourself a sporting chance on the climbs.Posted 8 years ago
Why not give it a go – nothing lost IMO – I’ve had single pivot SSs before and they were fine. Horst link design (eg your Spesh) should be fine too though you may want to add in some more compression damping (if you can) to deal with gurning low rev climbing.
Ratio – normal SS ratio eg 2:1ish to start. I’m on 32×17 FWIW
I currently have this as a SS option 🙂

i have been running full sus single speed since 1999 on a marin mount vision and later on a whyte preston
always run 2:1 but i run an old skool sunn bb mounted tensioner , it has been reliable for 11 years now just needs new jockey wheel every now and then
most normal tensioners wont pull the 17mm of chain that the marin or whyte needed ,
i always run a 36 front ring as bigger is always better in life
both bikes are a bit heavy compared to something like my ragley td-1Posted 8 years agoeviljoeSubscriber
Just about to SS my old Voodoo Canzo ti- it’s a URT 🙂
Using a blackspire stinger, will see how I get on.
If there are chain growth issues, why not just use an old mech as a tensioner? You can set it with a cable turned the wrong way round, and it will move with the suspensionPosted 8 years ago
