BTR Frame Corner Bag



Nicely executed frame fit bag though very much a tour, rather than trail biased design

The BTR frame corner bag has been a pleasant surprise and is arguably the optimal size for the design, especially on modern semi/compact geometry framesets. You get what you pay for and in this instance we've another sturdy, easy-care leatherette nylon shell with obligatory Scotchlite detailing, generous nylon mounting straps and zippered entry.

There's enough room for spare tube, medium sized multi tool, micro jacket, patch kit, micro pump and tyre levers, though the fabric will accommodate moderate expansion; I've managed to cram a slimline smartphone in as well.

I've combined ours with rack bag/pannier, using the latter as tool/tog caddy and this for wallets, phone, pens, batteries and other stationary stuff I don't fancy rummaging for.

Line the base with bubble wrap for peace of mind and remember a waterproof carry case since while the fabric's pretty impervious, stitching and zippers are anything but. Casting a garden hose evenly across its surface saw water forcing entry within thirty seconds. Real world wet stuff is less problematic given it shelters beneath top and seat tubes, thus heavy downpours bead and slide harmlessly away.

Aesthetics aside, it doesn't swing like a hammock or otherwise impede pedalling when tethered tightly, so it's a viable alternative for clutter-phobic riders wanting to haul a little more than expanding wedge packs usually allow. Retro-reflective detailing worked better than I'd expected too, accentuated by some furious acceleration through town. However, these tour-biased models are less convenient than shoulder holders when carrying bikes, say running though rutted stuff on a crosser or indeed, up a flight of stairs.
