I alluded quite obviously to a known cycling product a little more than a week ago. I'll straightforwardly say that Christa at ERR more than took care of our dispute and I publicly thank her for it. As suspected, she was having a tough, busy time and things sort of got away from her, but not anymore. Below are pics of the (left side) MFB that I ordered, not necessarily for the QB mind you, but for gravel grinds and long ones.
The only initial impressions are ones based on an easy 25m in-town stroll, so I'll have to put it through its paces to get a real feel for the product. That said, I'm impressed by the build quality. It feels substantial and solid. the straps are ample and well-stitched. The body has some form and cushion built in, which is great for my camera (which may be a primary usage for me), and has enough space for a camera, cellphone, a bar, and a bag of something perhaps. It would also hold another bottle I think. There are also 2 side pockets, one of which held my garage keys, as seen in the 2nd pic. I think the side stretch pockets would be fine for things all the way in them, but not necessarily long items which could leap out.
The main pocket has an extension "skirt" and at the top a bungeed closure. There's not doubt you could secure valuables inside and have complete confidence. It went on in 2min or less and is very secure with the 3-strap system. I found that its placement didn't bother me a bit, but narrow bars could make for tight spacing. It'll be interesting on the LHT with its narrow 42c 'rando' bars. I can't wait to put it through its paces on a real ride; I'll pass along my thoughts at that time, but now that it's in-house, I'm very pleased with my initial perceptions. Way to go Christa!
