I have a set of tora's without the necessary poplock to lock out the forks. They seem to be expensive to buy, can I just use an old thumbie for this job, sorry if this is self evident.....

That might work. Be careful not to pull it too far though.
Thumbies pull a lot more cable than the poplock lever, and I'm not sure how the internals would hold up if you turn them too far.

good call might be worth using a front thumbie as these don't seem to pull as much cable- will give it a go 8)

Would a thumbie also give you on the fly compression adjustment aswell?

Cool beans chap if it works i will be tempted to do it. Think the poploc looks quite vulnerable not like a good ol thumbie.

I did this with a £2.89 plastic shimano thumb shifter from eBay.

When you set it up just make sure you leave a bit of slack on the cable so that even if you yank the shifter all the way round then you'll not get too much travel.

Would a 3 speed sturmey archer thumbie be better cos lhs thumbies move as much as the rhs one?
