Right.

Pump track in Chopwell should be completed and opened this week, so I need a jump/pump track bike.

Going to convert theBFe - Running a 32t oval up front, but have a 32t round if needed.  I'll probably go 15T on the back.  This means a tensioner needed - anyone recommend a decent, cheap tensioner and 15t wide base kit?

Edit: and some tyres...

I had a decent tensioner from Superstar Components. Not sure if they still sell them anymore. I'll have a dig around in the spares box after work tomorrow and if I've still got it I'll PM you. DMR used to do a Singlespeed kit with cog but that was years ago. I've seen people using bodged derealliers with them locked out with a really short length of gear cable.

I'd use a BB mounted stinger as a tensioner rather than any kind of rear mounted one.
Surly/velo solo and many others do a range of wide based rear cogs

If its just pump track 2.15 DTH's, if you'll be mixing up dirt DTH's will work but Billy Bonkers/Table Tops are also options

My Sidekick seems to have the magic ratio. The wrong one. In that it's just short of one link, but too long for the next one with a Stinger! So I've used a Stinger and an old rear mech. Looks crap, but the aim of the build was cheapness!
