It’s named after Will’s grandmother. We based it on the NITTO #352 (Albatross handlebar), but the Billie:
Ride it in the up or down position, your pick. If you have enough height with it down, do dat, to make the curves a better grab.
You can cut up to 15mm off the ends (if you want to..) and you’ll still have room for bar-end shifters. If you cut off more than that—for whatever personal quirky reason you might want to—stick with thumbies.
Overall: Excellent for everything. It can use a 2cm to 5cm longer stem than the Albatross—because it comes back more—but they’re both upright bars, no big deal, you’ll love it anyway.
