hi kinioo, plenty of useful advice there! as redbikejohn & uber says better to be prepared than stuck so here's my 2p's worth

unless you intend to run low, below 15psi, i would avoid rim locks they are not really needed and a ****** to balance.
a couple of short levers, buzzetti type with a 22mm socket and a 30mm section of 14mm allen key welded to the less useful end of the levers works for me.
for inflation a cheapy 12v pump with the casings removed is the bussiness just mind your fingers!

wether you take tubes or repair kit what ever suits you, personally i carry both tubes
