I have rebuilt an old mtb hardtail into a city bike, with 1.5" slicks and a rigid fork. I mainly use this bike to attach my five year old's "half-wheeler" trail-a-bike. My bike currently has really wide profile carbon MTB bars that I would like to cut down for road riding. I realized that there are aluminum inserts in both ends (semingly to reinforce the ends of the bars?). If I cut down the bars, I would saw off the ends that have these aluminum supports. How important are these internal reinforcements? I do have bar ends and like to use them for climbing (pulling 80lbs of kid plus trail-a-bike I need all the help...) Will the tension from the bar end clamps and/or the tension on the ends of the bars cause trouble if I axe the reinforced ends? Not wanting to risk a failure I have not messed with anything yet, but it seems like a carbon bar should be plenty strong.
Any ideas or input? I'm tempted to just pick up a used 40" alu mtb bar and be done with it.

They are for barend support. W/o barends, just cut them.

the reinforcements are there for a reason! in addition, there are typically internal reinforcements where the brake levers are mounted, so again, cutting the bars means the brakes are now mounted on an unreinforced area. don't cut, just buy another bar.

On a straight MTB bar? How do the bar manufacturers magically know where you'll prefer to have your levers?

why don't you ask them jasper? get an old spoke and feel inside the tube for the upper & lower limits of the reinforcement. then check that against the average clamp position for the typical brake fitting. maybe the manufacturer just made a lucky guess?

measure typical barend clamp. Measure typical grip width. Measure typical brake lever clamp. Add in a fudge factor or say 2" or so and reinforce that area to allow the brake clamp. Not that hard to figure out. ---------------- Alex
