Need some help with my new tricross single speed....

first one - when i get a puncture and have to take the rear wheel off.....

How do i get the tension right when i put it back on ? Also can i use a normal QR skewer or even a halo hex - i don't want to carry round two spanners !

Secondly, what ratio do you recommend for a beginner ? The tricross comes with 42 at the front and 18 at the back...

I ain't going to get up a lot of the hills around here...

thanks 🙂

1 ring spanner is enough

Pull wheel back and nip up gently - QR won't hold securely

Try a 39t - Surly do a suitable one

TTFU 🙂

good point though

well..

commuting and general rides when I just grab the easiest thing out the garage....

I suppose its the choice between getting up hills and spinning madly on descents ?

I can get up most stuff on the 39 - and 19-20mph on the flat before you spin out....

Have you got a chain tug fitted? I find these helpful in getting the chain line straight and tensioned when you repair a puncture. Still need a spanner for the bolt though. The stock wheels on the tricross are poor, so a slightly misaligned chain can accelerate wear and tear on the hub - mine only lasted a few 100 miles.

It's not possible to choose a ratio for a SS CX bike that will do everything - the difference in ratio necessary for proper trail work and beasting along down the tarmac is massive. It's a bit different from a SS MTB in that sense. The stock 42x18 is a good start - this would be on the light side of things IME, you wouldn't want to go much easier than this if you're riding mainly on roads.

I run a 32-18 and i can still pedal at 16-18mph on the flat and i am by no measure that last to the bottom of a fell/hill.

im on 52:18 but its only used on tarmac, and keeping up with traffic is more important than anything else.

the hills took a while to get used to.
