i don't need a spanner for my wheels as i use goldtec allen key bolts but i think you can get a spanner with holes in so it mounts on to bottle bosses? i have seen a short one that fits in a jersey too but i would be tempted to tape to the underside of the saddle or seatpost.
riding without a bag is quite liberating after years of commuting with bag or using a camelback on the MTB.
