Cool. I had a look today, there’s quite a few tools. There’s no tool I’d say is crucially missing for most bike repairs to be honest.
Off the top of my head, some things that might be handy and I couldn’t locate:
-MTB and road brake cables, and housing. Maybe a set or two for urgent weekend or nighttime repairs when shops are shut?
-Gear cables and housing. As above.
-Couple of thin nitrile gloves for greasy goods.
-Torque wrench(s) especially for working with carbon parts. 2-20ish Nm, and less important one going up to 65Nm for installing bottom bracket bearings, cranksets and crank arms.
-Cone or other thin wrenches for adjusting axle bearings. 13-17mm are the most used, need two of each (Halford’s Bike Hut brand sell a good, cheap set approx. £11). The Space has a 15mm pedal wrench and I think a couple larger thin wrenches.
-Derailleur hanger repair tool. Uncommonly used outside a bike repair shop, but I’ve been drawing up plans to fabricate one so perhaps we could have that eventually.
-Wheel building station, which is mainly two vertical arms to hold a wheel stable while it spins. Definitely not a necessity but it might be cool to run a wheel building workshop one day, for folks to learn to build and repair their own spoked wheels?
-Grease. I expect there’s some somewhere. Best grease for non-high-performance cycle hubs is calcium marine grease (caveat emptor: unless manufacturer says otherwise), cheap as chips.
-Do the air compressors have Schrader or presta valve adapters? If not that would be handy.
-Breaker bar or long 1.5-2” pipe, for leverage on bottom brackets and stubborn parts.
-Bashing block, chunk of wood to hit with a hammer to protect finish on bike parts.
