I read somewhere that the Woodchippers can be trimmed down if you like and still have plenty of grip area.

From the comments to this review:

"Nothing like a timely reply…I’ve been using these ‘bars on a new Lynskey Ridgeline for about 5 weeks now. The other night, I was noodling around the Salsa ‘site and I saw a pdf for the Woodchipper bars, which noted that the extensions were extra long, to allow trimming. Shazam! Out to the garage, hacksaw flailing, and after 10 minutes, I had trimmed about 1.5 inches off of each end. Doing so ended the “unintended-knee-shift” syndrome I was seeing sometimes. There’s still plenty of room to move my hands around, and they’re a little narrower than previously (I have the 42 cm versions). The pdf also notes the presence of cable grooves, which I am unable to detect, but I like the full round profile better."
