13.4/18.3 sidecut, IIRC. This one was probably too soft for my 175 pounds… it felt a bit sluggish on initiation and then bend too sharply in the middle when I pounded on it.

Rode both with and without a Donek plate – I preferred it without.
Easier to get it leaned waaaaayyy over than its bigger cousin.
