I finally got my 2nd Coker built with my Airfoil rim on Saturday and had a chance to get a little bit of time riding it yesterday and today.
Wow! Having ridden with the stock rim for three years, riding with the Airfoil rim made the Coker handle like a completely different machine! I can’t say that I like the Airfoil rim better or worse… though it is certainly stronger – so it is better in that regard.
While the Airfoil rim makes the Coker extremely nimble and responsive, the lighter weight rim also makes it less stable. On the one hand it was nice to be able to maneuver and accelerate/decelerate with such little effort, but at the same time it was easy to over control when making high speed aggressive turns.
The steel rim feels significantly more stable in aggressive turns due to its heavier weight and flywheel effect – you can just plan your entry, dive it to the desired lean angle, and essentially hold on for the ride! The aluminum rim Coker felt more skittish in aggressive turns and didn’t give you the same feel of locking into the turn as you get with the steel rim Coker. The greater weight/stability of the steel rim Coker seemed like it could be preferable in various specific riding circumstances. On the other hand, it was awesome to be able to plow up decently high curbs like they were nothing with my Airfoil Coker and hardly feel the impact! I can’t wait to do some drops that I wouldn’t attempt with my steel rim, too.
I read that some Cokers now come with a stock aluminum rim. Is the steel rim still available? Does anyone know if Coker is planning to phase out the steel rim and only use aluminum rims?
I just wanted to point out that the stock steel rim offers a specific type of handling that you won’t get from the aluminum rim which, in my opinion, is a real nice option to have at your disposal. I’m psyched to be able to have access to the aluminum Airfoil rim, which is incredible… but I’d hate to see steel rims disappear from the market.
