Yeah, thats what I said ... No, what I ment was... I can ride 40 miles. NOT 40 mph.


Thanks. I considered cutting the bar but there were several problems that led me to use the mount that I ended up with.

• The diameter of the road bars is larger than the diameter of flat bars the shifter was designed to mount to so even if I'd cut them I would have had to grind out the inside of the shifter to fit.

You just need an "older" bar ... one that is not lugged or the ones that are really fat in the middle, but the older ones with the small bulge in the center & I think they kinda rise up a little , so it kicks the drop part out a little to the side + that would help with the next issue.

• The bars are aluminum and my welder is only set up for steel.

No doubt, its the difference between a MIG & a TIG. : o)

• Finding a piece of aluminum tubing the exact diameter of the inside of the bars to reinforce where I had cut them would have been difficult/expensive. Also I put a lot of pressure on the bars sometimes and a failed weld or stripped set screw on the tops could = dental surgery.

IMO still do-able, just takes time... roll up a piece of flat stock into it if need be. Plug weld would be plenty, the preassure would go to the insert pipe/stock, make it longer than the clamp on the stem, it'll be ok. Its NOT like you just cut the thing in half then expect 2 or 4 spot welds to hold it, with out failing

• The mount I fabricated only cost $0.35 because the only thing I purchased was the set screw.
• I kind of like the shifter where it is. It's easy to read what gear I'm in and convenient to shift when needed.
Very good points, cant argue with that...
