So, I spent a happy evening sorting through all my trail spares and kit to trim it down a bit in weight and bulk. This is what I've got:
Trail kit by
ianbarrington, on Flickr
2x M5 caliper bolts (ti) (I discovered one of these can double as the handle for the chain tool)
3x M4 bolts (ti) - misc use incl. bottle cages, stem face plate, brake levers etc.
2x cleat bolts
1x 1/8" half link
1x 1/8" full link
several disc caliper shims
1x 8mm allen key bit (fits onto 5mm allen key) (for crank bolts, pedals)
1x spare tubeless valve
1x plastic tool for removing tubeless valves
1 pair of spare disc pads
Topeak chain tool with the handle removed
Ritchey CPR9 tool
J A Stein lock ring tool
Lezyne glueless patches, tyre boot and little metal rougher-up thing
The Stein tool and patches etc go in their own little case, the rest goes in a gaffer tape reinforced plastic bag. That all comes to 164g.
Additionally, I have 1 spare tube (26" to stretch into a 29er tyre if I need it), a Park tyre lever and a Lezyne pump, with two velcro straps and some gaffer tape wrapped around.
450g all in, which is about 70g lighter and a little less bulky than it was before I started
