This is the Porcelain Rocket 52Hz frame bag designed for Road frames, in a medium (now a collector's item!). The seams are welded and it has rolltop closure so is completely waterproof.
Bought this last spring intending to use it on my Hook, but it was a smidge too small (my Hook is a Large) and with everything happening last year I didn't use it at all, other than trying it on for size. The Hook is going to be sold now. Oddly, it kind of fits my Jamis Dragonslayer Large frame a bit better but I've also been trying to sell that, and have had a custom bag for that frame anyway.
Measurements are in the last image below.
Price was $215CAD (£125) plus postage plus VAT.
Looking for £90 including postage within the UK...
