Thanks so much, Leah! I have a couple of other Riv build videos you might like if you haven't seen them, check out my channel. I had to go really, really far outside of my insurance network just to get a referral for Dr. Ron. Healthcare, I tell ya.
I love the Billie bars, they're great. Running them with bar-end shifters wasn't working great for me as I sometimes did have thigh interference. That was the only issue. Love the grip position ahead of the bars, the shape, the look. If I'm to be honest I really resisted switching up the bars but a lot of my bike friends swap and try things out with abandon so I figured I should just loosen up, already.
The Ortho Bars are fun, they are crazy wide and they have a ton of flex. At first I wasn't so into them because I thought I'd lost the grip position "ahead" of the levers and shifters which I use a lot for climbing or getting out of the wind. Or sprinting. But after I re-routed the cables from the shifters it was all gravy. I've definitely resolved the bar-end jabs issue. Compared to the Billies I can't say they're necessarily better, they're different, they're good. They were made at the Renthal factory, if anyone's curious. The new-to-me Suntour Power Thumb shifters are really great, I love them. They're my first reverse-mounted thumb shifters.
Joe, thanks for the note. I didn't know that mocking up the struts with a bevel was a thing either but it just sort of dawned on me. I'm glad you enjoyed the consultation. I definitely love the Billie bars as well. I'm sorry to hear about your numbness! and I hope that resolves some how some way.
