Agreed. I know it won’t happen but a small run of Boscos and Chocos in 31.8 would be awesome. > On Oct 15, 2019, at 9:13 PM, Joe Bernard wrote: > > Everything you've described - most of which include a different stem and/or > bar design - are intended to combat the physics I'm talking about.

Speaking of such matters, I was at RBW today and rode a Wolbis with a prototype Bosco Bullmoose that reaches back a bit less and flared a little more.

Re: [RBW] Issues with slipping bosco bars?
Surprised to hear about this. Never had a single out of spec Nitto item nor have I ever seen one in person and there have been plenty coming through my hands. Only ones I am even aware of are some bars that were stamped with the wrong width. CSHBGCA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Issues with slipping bosco bars?
They ought to have, but this isn't the first I've heard of or experienced myself that the diameters can be off just enough to be an issue.

Re: [RBW] Issues with slipping bosco bars?
I switched to bosco moose on my Riv-built Clem for this reason. I'm a big guy, and a couple of times at very sudden stops, I moved the bars in the stem significantly. The integrated stem removes any worry.

Re: [RBW] Issues with slipping bosco bars?
Well, I stand corrected. I've never had a properly set up bar bar slip except for cheap steel bars in cheap steel stems, and even that problem was fixed with a box wrench (ie, it wasn't properly set up). I guess that yes, the Bullmoose makes sense now.

Re: [RBW] Issues with slipping bosco bars?
The technomic with its steel backing plat will handle a good amount of over torquing. Same with the sleeved boscos. Grease stem bolt and underneath bolt head and apply friction paste.

The stem is a properly matched 25.4 nitto technomic deluxe. I will try the friction paste. Thanks for the tips.

Re: [RBW] Issues with slipping bosco bars?
Forgot to add that a properly made and properly sized, 1-bolt, 25.4 mm or 26.0 mm bar and stem combo won't slip either, in my experience, which is pretty extensive. That is to say, in normal use *they will not slip.* *One of the main reasons 31.8 makes more sense. Slips substantially less.* *I prefer 2 and 4 bolt open face stems myself, or at least a steel single bolt one. I've never had any of those slip. * On Sat, Oct 12, 2019 at 3:01 PM Patrick Moore wrote: > If the stem and clamp area of the bar match as they should, the bar ought > not to slip, at least with forces normal to normal riding.

Re: [RBW] Issues with slipping bosco bars?
If the stem and clamp area of the bar match as they should, the bar ought not to slip, at least with forces normal to normal riding. Does your stem have a clamp that is sized to the bar? If not, you can shim it; Riv used to sell a shim for this purpose, and you can also cut one from an aluminum can. I've used both sorts. Loctite or friction paste ought not to be needed for properly matched parts, at least these sorts of parts. But friction paste does work when bars slip, at least if the gap isn't excessive; My Dahon Hon Solo has a QR clamp that is poorly designed and does not squeeze the bar sufficiently; friction paste works well (as does a retro-fitted *all steely steel, internal cam, repurposed Campy seatpost QR* in place of the wimpy external-cam original).
