Specialized 04 Durango Grips
These came stock on my P1 and I have been loving them ever since. In fact they made me think twice about lock grips which I thought I would never depart from.
Pros: solid feel/grip, lightweight, stays tight on bar, works well with or without gloves, no need to worry about sharp metal clamp or barend plug.
Cons: harder to install/uninstall, rubber life (bit thin), plain and simple.
