The name for Neutron Components first product says it all. The O.S.K., or Oh Shit Kit, is tucked neatly into your handlebar, always there to get you out of a jam. The latest in a growing trend of hidden, always-there multi tools, the OSK comes to us via Aotearoa, New Zealand.
Designed to fit standard handlebars with an inner diameter of 19-21mm, the OSK uses two different sets of o-rings to slightly adjust the fit. Like most of these tools, they’ll work best with grips that have open ends since you need to be able to access the end of the bars to get to the tool. Some grips with closed ends can be modified to work, but for the best results Neutron recommends lock-ons with open ends.
The full OSK includes inserts for both sides of the handlebar with a wrench on one side and the chain tool on the other. The main tool body and bar end plugs are made out of a composite material to keep the weight down which results in a total system weight under 150g.
