The Rockshox Recon Silver Air is a great upgrade fork if you want to get rid of the old Suntour coil spring fork that came on your bike. With an air fork you shed usually almost 2 lbs of weight off the front end and greatly improve the feel and adjustability of your fork. *The Judy and the Recon forks are very similar with the Recon being stiffer and slightly better performance (it has bigger stanchions 32mm vs 30 on the Judy). Most people may not recognize the difference but if you are a bigger guy you may prefer the Recon for the increased stiffness.
The Recon has an air port to increase or decrease the air pressure depending on your weight and preference. It also has compression control and rebound control to fine tune how you want it to perform.
Specs: Straight steerer tube (not tapered), Quick Release 100mm (so not boost). In 27.5” wheel option they have 100mm and 120mm travel options
