August 12, 2021

I would like to know if the 2021 RT Sea to Sky handlebar is 1 1/4 or 1 1/2 inches. I want to mount a cup holder with a U-clamp.
The RT handlebars are 1 1/4 inches for mounting ram mounts etc.

I come up with 1.125 on my dial caliper

I ordered the 1 1/4 u bolt. It should fit the Sea to Sky handlebar for a cup holder.
Thanks for the reply. Ryde safe. I had a dial caliper years ago, but lost it someplace. LOL

it is considered a 1-1/4" bar

I thought considered a 1-1/8" bar. Oh well.. either way.

Since Spyders are metric its probably 30 mm.

28.575mm

You measured it with calipers, right?

The 1.125 yes the 28.757mm was crossed on google inch to mm

Yup .. Again .. 1-1/8"

OK, I sure wouldn't have expected to see an American size component on a metric designed product. The handlebar must be a US designed and manufactured product w/o a similar metric size competitor.

Well ... All my past metric bikes used either 7/8" or 1-1/8" bars. My H-D was 1-1/8". Guess I can't recall any mfr listing them in mm's.
