    PSA Dimension Polyant VX21 Durability...

    I made a nice frame bag a few weeks ago for my Salsa Fargo, using Dimension Polyant VX21 which I thought felt like it would have impressive durability.

    I got the chance to try the bag out on a local charity moutain bike ride a couple of weeks ago, and it performed perfectly, holding all the stuff I would normally have in my backback.

    Anyway, once I'd removed the mud I found that after only 22 miles I'd worn two small holes in the fabric. One where it touched the bottle cage and one where it touched a bottle cage bolt on the seat tube.



    I've patched them using some shoe goo glue and a couple of bits of innertube, but I thought if anyone has made anything similar for a big ride but hasn't yet tested it they might want to do so before they find themselves with stuff falling out of holes! Any obvious wear points definately need reinforcing.

    Thats great to show that. It's amazing what a small amount of vibration/rub can do after hundreds of hours or miles.

    For this reason, I only use 1000D Cordura for the 'edgeband' that contacts the frame. Tough stuff without too much weight.

    I've yet to see one wear completly through :thumbup:

    it's key to remove bottle cage bolts and cover the holes. The typical square edge bottle bolts will wear through just about anything in time.
