The choice of many trekkers, mountain bikers, and touring enthusiasts. The Flyer and its ladies model Flyer S are classically sprung saddles for long distance trekking and touring. Sharing the same leather tops of the B17 models, they combine the comfort of these popular models with the extra suspension granted by two rear springs. Both are available with tubular steel rivets or with hand hammered copper rivets.
Strengths: It's a Brooks. Everyone should try one sometime. And it's mighty nice looking and feeling, too.
Weaknesses: None. Well, the weight of the springs, but if you care about that then you're not reading here for information.
The Flyer is pretty much the B-17 saddle with springs. I didn't know quite what to expect, but boy am I glad I got the springs!! Here's how it feels: not springy at all. Firm ride and all that. Then I realized that zero shock was coming through the seat. No bumps, just smooth. The springs work!
Lickbike.com was good, and their price was a lot less than most folks', even used on Ebay! Shipping charge was at cost. Total for saddle was $91.60. Another well known bike shop wants $124.95 + s&h - go figure.
