"Firm up the handlebars"???
http://cgi.ebay.co.uk/ws/eBayISAPI.d...tem=7129546972
"Keen cyclists will know that this gadget is used to firm up the handle-bars." I thought I was keen but I've never heard of anything like this. Is it meant for repairs or what? Firming is nonsense, I guess. ~PB |

I wonder why they don't make bars with a piece of wood, plastic, or CF in the bar at the clamping area. When the bar failed, you'd get time to bring the bicycle safely to a stop. I am told that this is a trick that they used to do with steerer tubes when failures were not uncommon. |

like a shock tower to shock tower bar on the front end above the engine
with engine mount type bushings or not. metal flexes! some auto designs shake and rattle up there under non-commute loads. consider the: on the seat, off the seat or one pedal down one up or best both even when cornering. The frame, a truss like a roof truss has + and - pressure areas that shift around in action. best loaded evenly at the bottom to reduce compressive loads squeezing down from the seat seated may not be noticeable BUTBUTBUT! add a gorilla or slide the volvo over a dirt road at 80 and then metal parts then begin to flex noticeably. |

Firming is nonsense, I guess. ~PB Dear Pete, I doubt that the add-on brace helps short, flat, straight off-road bicycle handlebars. But handlebar braces are quite common in the off-road motorcycle world where handlebars are wider and their curve is quite different: With an add-on brace, this: ______ ________ \ / \__c_c__/ becomes this: ______ _______ x----------x \__c__c__/ and the flexing at the handlebar clamps "c" is greatly reduced, leading to much longer handlebar life.

I thought I was keen but I've never heard of anything like this. Is it meant for repairs or what? Firming is nonsense, I guess. Trick-bike stuff used with long riser bars. I've seen a couple of them on freeride bikes. I've also seen a bike that was more of an art project which used two such crossbars to provide additional space to mount stuff.

Is it meant for repairs or what? Firming is nonsense, I guess. No, it does what it's supposed to do. I have such devices on three of my bikes, and I have handlebars with welded crossbars on many others (at least six, but it's difficult to keep track). Handlebars flex around. The taller or wider they are, or the more force you apply, the more they flex. A crossbar allows one side to support the other, which greatly increases strength and rigidity-- much the same way that your bike is stiffer and stronger with a top tube than it would be without one.

Thanks Mark and everyone, that does make sense. Obviously I'm not a keen mountain biker :-$ ~PB |
