Riser Bars with "Narrow" Centered Rise to Accommodate 54cm

All my flat bars are 54cm width, and yesterday, I excitedly chopped my recently purchased 3" riser bar down to 54cm...

I wasn't able to get the shifters, brakes and Ergon GP-3 Grips on even though I tried for quite some tome to file and sand down some of the aluminum- the bend simply came too prematurely.

Can anyone please advise?

Thanks in advance for your help!

Run wider bars and be happier or get some GP3s for gripshift which will be shorter grips and hope you have enough space on the super narrow bars.

it''s a stupid mistake caused by your failure to preplan the task at least that's what my buddy at the LBS told me WHEN I DID THE SAME THING ............................. in my case it was a fixed i and went brakeless until i came to my senses

You didn't say what bike or drivetrain you have, but Shimano does make integrated brake/shift units, which take up less handlebar real estate than separate brake levers and shifters:

Something like an Alivio 9 speed shifter should do:

You are not running a CUES groupset, right? That one is a whole different animal.

I'm guessing you're using a 31.8mm bar? A 25.4mm bars would be leaner in general, and it is easy to find as they are common in the 90s. You would need a new stem, but the bar shouldn't cost much.

That’s a good idea, and a 25.4 shim to 31.8 would be another alternative to replacing the current stem.

Just go single speed, and you don’t need the worry about the shifters. 😊 Jk.
