Sahmurai Sword Integrates Tubeless Tire Repair Into Your Handlebars

Stefan “Sahmurai” Sahm developed the Sahmurai Sword out of a frustration with the problems surrounding storing and carrying automotive-style tubeless repair kits. While an effective mode of repair, the sharp barb of the reaming and plug installation tools have a tendency of puncturing gear or clothing (or skin) making them hazardous on the trail. The tire plug material tends to get dusty or dry out if exposed to dirty or dusty trail conditions, or the contents of your bag.

The Sahmurai Sword resolves all of this by integrating the tools and storage for several plugs into the ends of your handlebar. Cut down on flats next…

By tucking the system into your bars, the Sahmurai Sword system is always on you, the plugs stay clean, and your gear and clothing will be safe from errant punctures. All riders need to do in case of a flat is twist off the bar ends and get to work. After removing the cause of the flat if it’s still there and finishing the hole with the reaming tool, the patch is pushed into place with the installation tool, and ends of the plug material can be snipped (or not).

Boom: easy tire repair on the trail out of a system that literally won’t stab you in the back.

Cool idea. I’ve been driving on a tire plug in my car for almost a year, trouble free – but I wonder how well these plugs work with the comparatively thin casings of MTB tires.

How many tubeless punctures on the trail (not managed by sealant) will be fixable with this? Certainly not a sidewall puncture or tear. No flat that results in losing the bead. This seems like a product that doesn’t actually solve any real problem. You need to carry a tube in any case.

Yes, but what about the times you get a good size puncture and you loose complete preassure and 90% of your sealant?

Not mentioned, although obvious, is that this only works with tubeless tires, with juice of some sort.

I have used the Hutchinson plug kit (basically smaller version of the automotive ones) for a long time. They work great at sealing holes that are too large for sealant. Obviously if you tear a sidewall, you’re doing something else, but this is an elegant solution. (OTOH, I haven’t had much trouble fitting the little tubeless plug patch kit in my saddle bag.)

@craigsj – the problem he’s addressing is clear: “problems surrounding storing and carrying automotive-style tubeless repair kits”. Maybe you don’t have that problem – I don’t – but that doesn’t mean it’s not real.

Clever, if that is part of your flat repair arsenal. My only concern would be the end caps falling out, and V 2.0 could include an expanding bar plug.

They clearly expand–just like a carbon steerer plug.

I routinely tap a bar end at least once every ride. I’d not put anything I needed to get at inside there. Inside my crank spindle, on the other hand, would be a great spot for this.

this is the same product cars and motor bike use, just slightly smaller and for bikes.
the interesting thing is not the way it works – its that it fits in handle bars.

Difference with a tube is that you dont need to carry a spare tire (yeah thats only valid for week-trips and the like) and its faster to use. And of course that wont work for slashed sidewalls.

So yeah, you still need a tube, it’s not useless either. Now to take this on the trail or not, hard to say, I guess for most its not needed.

Too bad the kit doesn’t fit Syntace carbon handelbars due to the handlebar’s wall thickness.
And yes, Stefan Sahm is German.

This kit makes a lot of sense if you live in South Africa or the desert south west. Tubeless pinch flats are common and the 1/4″ holes don’t seal well with sealant but tubeless repair kits work amazingly well. In desert regions tubes can be a pain. You can have 30 thorns in your tire and its hard to find them all. Kudos to another use of empty space especially if those are expander plugs.

I ruin a couple few tubeless tires a year pinching holes thru them, this is awesome. I looked up Genuine Innovations plug kit, but I dont ride with pack so did not order a sharp object to put in jersey pocket. This guy had a great idea, and made it.

We have been using this type of tubeless plug system for years, very, very necessary in South African conditions. You may still need to carry a tube for a big sidewall cut, but, i have and use one of these Sahmurai swords, works great. Stefan is German, but lives in South Africa, well done bru!

@MsC: it will be interesting to see if you can modify them to fit Syntace bars. Maybe the will not lock up anymore, but they seem like such a great tool. I’ve used similar stuff on bikes and cars before and it works great.

This would be great in new orleans where carrying a hidden prison shank could be a difference between getting robbed/stabbed/murdered.

This a great idea. But some use a set of grips that occupy the bar ends.
He needs a version tat fits up into a tapered steerer from the bottom.
