Re:
I think someone did ask about STX recently but few replies.
Tonight I've taken the reflectors off and had a better look at it. Needs thorough clean but it seems to have been kept ok mechanically. I've swapped the god awful seat for a Selle Turbo-matic II for now. I love the Panaracers on it, changed the front tube as it had Slime sealant leaking from the valve rim hole and pumped them to 60 psi. Feels really good on road, just need to get the shifters and gear cables sorted, tidy it up a bit and I can get to riding it properly.
