General cycling advice ( NOT technical ! )
I've been very pleased with TF2 spray, and indeed if I'd been unable to get the Tri-Flow I'd have gone for the TF2.
Update on the Triflow..... it seems to hold dust/dirt and much and get a bit 'black sludgy' more than TF2 aerosol. I don't recall the Triflon ever doing this, but that was when I lived in Essex and the roads in Norfolk are a lot more gritty. I suspect the Triflon will fare better in the wet (than TF2 aerosol)though. Test continuing.
