Good quality rim nuts from SIP. Thes don't have a top end cap on so they can be used to fit tubeless rims or handily a standard split rim to a hub with the longer studs in if you say, get a puncture. Ideal to have in your toolbox if your mate is carrying a spare. Alternatively, these can just be fitted to any split rim as standard.
