modify dropouts?

2nd build. The first one went so smoothly I went into my wife's build maybe a little cocky.

The bike is her pride and joy - a Norco that she loves. This ups the stress level for me. The pics probably tell the entire story - looking for recommendations on how to make this work.

Thanks!

Don't mess with the dropout slots. Use a torque arm or two, outside the dropouts. I prefer to drill and tap a hole in the dropout to anchor a one piece TA rather than using a fiddly multi piece assembly with hose clamp like a putz. So it would make sense to use the left side dropout for that. If you can place a screw on the right without compromising the integrity of the dropout and replaceable derailleur hanger, then you can use TAs on both sides.

I'll second what Chalo said above.

And in this image, you show the axle installed the opposite way I'd recommend--you want the cable to go down in a "drip loop" so the axle exit slot would go down, too.

Since you aren’t using disc brakes you don’t need to modify. If you had disc brakes, then filing the dropouts 1mm deeper will allow the 12mm axle to mount with the same axle centerline as the 10mm bicycle axle, so the brake pads would be aligned.

You guys are great. In a shocking departure from the norm I listened and followed (nearly) your advice.

I did slightly tweak the dropouts to allow for the larger diameter bolt to seat to the bottom of the dropout. Maybe picked up a mm+ but it made me feel better. I through bolted a torque arm and switched the orientation of the hub wiring as well.

I did not use any washers on the outside of the sprocket side as I felt the flanged nut would bite into the aluminum a bit and provide a more secure connection. I hope the gurus agree.

Thanks guys. It's always fun to put the first 4 hours into a "one hour install".

edit - I was just checking the fitment earlier before mounting the brake disc.

Try to check your pad wear or inspect the rotor after a couple hundred miles to make sure all is good.
