I am used to carrying a spare folding tire with me on extended tours. In the past, I used a Cannondale Cordura nylon tire sock (circa 1982) to carry 1-2 spare 27"/700C tires. Sometimes I'd even carry a couple of these tire socks in goathead thorn/puncturevine country, each full 'o tires and some additional spare tubes and patch kits.
Now, I have a Sherpa and need something that will allow me to carry (at least 1) 26x2.0 Schwalbe Dureme folding tire. It would be nice if the same sack could also carry a spare tube or two and another couple patch kits. For really poor conditions/extended back-of-beyond tours, I'd seriously consider carrying a second bag as well, and toss in a pair of Mr. Tuffy liners for thorn country.
I am having trouble finding a suitable tire sock (as we called them when we carried spare sew-ups)/bag that is long enough x wide enough x thick enough to fit the folding Duremes. Most of the models I've seen on the market, for example, http://www.jandd.com/detail.asp?PRODUCT_ID=FTBII
are long enough, but not wide enough or thick enough.
The folding Dureme that arrived in the mail yesterday measures 24cm long x 12.5cm wide x 8cm thick (when squished together). In inches, this is roughly 9.5"x5"x3".
Any recommendations before I order up the Cordura fabric and break out the sewing machine? Would a smallish, lightweight dry sack do the job? What do others do? How do _you_ carry your folding spares so they are safe from direct abrasion, wear, and general mischief when traveling on terrible roads away from any possible resupply? I used to secure mine to the tops of my panniers, but have also carried them inside when I have room. My rack-top dry sack snuggles under the saddle, so there is only room under the saddle for a small sack with spare tube, a couple patch kits, mini-pump. tire pressure gauge, tire levers, and maybe a multi-tool, depending on size. Other tools reside in their own sack deep within the panniers for more major repairs and maintenance at camp.
Thanks in advance,
