Re: [RBW] Re: Issues with slipping bosco bars?
My aluminum 58cm boscos flex like crazy. They are super light and thin walled tubing. The flex is so much I wonder if they would break but probably just in my head. There is extra comfort from the flex a bit like doing push-ups on a diving board instead of concrete Al in Saratoga -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: Issues with slipping bosco bars?
7:54 am 10/15/19 With my first-run aluminum boscos, I was eventually able to tighten them enough to quit slipping, but I still didn't like how much they flexed/twisted. So I ended up with the steel bullmoose version which are perfect in every way. If I ever try the aluminum ones again, I'll use the nito v4 srem, which might well solve BOTH problems. Seems like this would be a fix for any that have been over-tightened and ovalized, too. But that'll have to be a bike with a threadless steerer.

[RBW] Re: Issues with slipping bosco bars?
I was test fitting Nitto RM016N "Mustache" handlebars to a Nitto "Dirt Drop" stem, and doing so marred the handlebar's clamp area because the stem was just a little too small for a slip fit. Not much, just a tiny bit, but I thought, "Wait, What?!" Both the bars and stem were prominently marked 26mm and the bars measured 1.024-inches (26mm=1.0236 inches, a nominal 4 ten-thousandths less than my bars measured). Oh well, even Nitto has manufacturing tolerances, or they wouldn't also sell stem spreaders. On the other hand, I need to check out the carbon fiber friction paste others have mentioned, because I have another bar-stem set that slip a little, even though again the numbers match and they should mate. Trouble with the integrated bar-stem system is that I like to fine-tune the tilt of the bars to suit my (no longer mint condition) wrists. Eric, Spokane P.S.

[RBW] Re: Issues with slipping bosco bars?
I feel like slippage has little to do with bar weight or stem length. If you want less slip then you need to increase friction between stem and bar. A larger diameter bar/stem interface (31.8mm or 35mm) accomplishes this most elegantly. Friction paste and torque are other means. More exotic solutions are bullmoose style stems (Nitto makes some) that clamp bars in two instead of one area.

Re: [RBW] Re: Issues with slipping bosco bars?
I had some cromo Bosco + Nitto old stock cromo riser stem (CT-## {31 or 51, maybe}) slippage. Not much, but a little upon hard out saddle mashing or stopping. I may or may not have experienced the same with the stock Tallux on my Clem... I can’t recall as I swapped stems fairly quickly as I needed the Tallux long quill length for another build and the Cromo riser with short quill was a perfect substitute at the time. I later traded the Cromo Bosco finding the 55cm too narrow for my large wingspan (for the bolt upright posture.) I’ve decided if I try Bosco again I’ll look for the 58cm moose variety, not just to avoid slippage but also a preference for the style (and to complete a bull moose trio.)

Re: [RBW] Re: Issues with slipping bosco bars?
Hello all- Out of curiosity, does the metal make any difference in slipping? If you had a slipping set, what was it made out of? Boscos come both in heat-treated aluminum and chromoly steel. I put a pair of Boscos on my Raleigh Crested Butte four years ago to replace a pair of Civia Duponts. The Duponts were similar, but (probably untreated) aluminum and had quite a bit of "flex" in the bars. I got the Boscos in steel partially because they were cheaper than the aluminum bars, but also because I wanted a less "flexy" feeling. Four years later they're still working good, and I haven't had any slip. Best, Shawn in PDX -- You made it all the way down here! Yay!

Re: [RBW] Re: Issues with slipping bosco bars?
Without actually measuring anything you have idea what you are working with, either bar or stem. Even if the bar is slightly out of spec, an open face stem is much more accomodating, the bars don't have to be exact like a single bolt. I've used 25.4 swept back bars in 26.0 open face stems w/o a shim and they didn't budge. 2 and 4 bolt stems usually offer a wider clamp area also. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Doubt they are defective. I think it has more to do with how and where a person rides. Some friction paste and judicious overtorquing of stem bolt should mostly solve it.

Go to a bike shop instead. It is usually sold to install carbon seatposts and bars that are sensitive to over torquing.

It takes a substantial amount of torque to keep those bars stable. I was one of the first to try them years ago and they called a few weeks later to see if they were alright. I had to use a pipe as an extension on my allen wrench to get them tight enough. They have a freaky long reach back creating a lot of leverage. I wouldn't trade them for any reason.

Sorry to hear that. I think it’s just poor design, unfortunately. Too much leverage from the long bars and not enough surface area in the clamp. The bosco moose seems like the safest way to go.

[RBW] Re: Issues with slipping bosco bars?
I had the same problem. Discovered that the bars had slightly deformed at the clamp area and therefore lost the strength of being a tube. I could tighten the stem all day but the bar would simply compress and slip with moderate force. Had to throw the bars away. They weren't safe. To be fair to Grant and Nitto I'm fairly certain that original damage occurred from a poorly fitted shim in a 26 stem. However the shim was only poorly fitted because the bars had slipped at some point. >From an engineering perspective the Bosco is pretty huge lever exerting a lot of force on that clamp area.

[RBW] Re: Issues with slipping bosco bars?
https://groups.google.com/forum/#!searchin/rbw-owners-bunch/bar$20slip|sort:date/rbw-owners-bunch/-0wcciQEqq0/gzdmgfBvDAAJ This is applicable. Seems like sufficient torque(with torque wrench of some sort) and/or blue loctite on the bolt threads. Carbon fiber friction paste also. Do measure both the bar and the stem, don't take it for granted they are what they say.
