These are crust rons ortho bars with Nitto 90-190 4 bolt stem 135mm. Yes, its a 26.0 handlebar with 25.4 stem, I just stretched the steel stem out a bit for a nice tight fit :).
Ron himself said he crams all his 26.0 bars in 25.4 stems, so figured I would do the same. Couldnt find a 135×26.0 1" quill anyways.
Was running a cheap tall 1 bolt stem, and it kept slipping (then I stripped it) so I needed to upgrade to something with more clamping force. Couldnt find much info on this, so thought I would post it here!

This is in my opinion the kind of thing you may practice for your own bikes, but not something to advise others to do *just in case*.
Just cause Ron does stuff doesn’t mean you should. The guy isn’t Sheldon Brown, nor does he pretend to be. I would never run a 26.0 bar in a 25.4 stem…EXCEPT perhaps for the 4 bolt stem you’re using. And even still I’d never set up a friend’s bike like this. Just not worth the risk when there are other options that are the proper fit.
Fucking around with the stem/bar situation is really being risky when the result can be smashing your face directly into metal at +20 MPH.
Awesome! I love Nitto
Nice rig…I can confirm this works quite well. On my bike (2 bolt alu 25.4 stem) feels like the bars will bend before slipping.
Running the same thing except it’s a single bolt. Works great
I think the saving grace here is Nitto stuff is ridiculously over-engineered/conservatively specced and tested to hell and back. And it’s a 4-bolt steel faceplate stem. I wouldn’t feel great about doing this with almost any other style of stem in any other material by any other manufacturer.
What’s the website to buy
Nitto stems and especially 4 bolt *chef kiss*
