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. I think Soma, blue lug and ben's all sell them: https://www.somafabshop.com/shop/product/nitto-stem-v4-2423?category=153 -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

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!

I think the OP has reached the end of his confidence with these bars and just would rather not.

Re: [RBW] Re: Issues with slipping bosco bars?
I've ridden these bars for many years. When I first installed them they slipped and I found that to fix it I had to tighten the bolt a little bit more than I was comfortable with—once I did, they were set and haven't moved a smidge since. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

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.

Re: [RBW] Re: Issues with slipping bosco bars?
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.

Re: [RBW] Re: Issues with slipping bosco bars?
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. I’m sticking with my albatross. I was happy with them anyway, just wanted to try something new.
