BlackburnGrid MTB Seat Bag(Return to Product Page)

Tough and simple. Easily holds 2 x TPU tube (or 1 x regular tube), tire levers, Dynaplug, some hex keys, CO2 cartridge and inflator (if you haven't gone electric yet), latex gloves etc. Water-resistant in all but the heaviest rain. No problem with loosening over 3 years of weekly use. Hard to know what more you need.

Small enough to be out of the way, just big enough for necessities regardless of MTB or Road bike.

I like everything about this bag. It's nice and roomy and easily fits all my stuff. Good zipper. Love the light loop. IMO, it would be a perfect bag if it also included a seat post strap.

This is the perfect size bag for fitting all required roadside fixes. Room for a spare tube, tire irons, large multi tool, 2 x CO2 cartridges, CO2 inflator, patch kit, and tire boot. The strap could be a bit wider.
