Recons are a spring fork where as Rebas are an air fork I believe
Nah, plenty of air Recon models, the older ones used the same lowers but with a slightly porkier upper and normally the cheaper dampers.
The newer Rebas have a different lower casting too, I think the Recons still use the older one though, but I haven’t checked.
They are lower int he range but the top end Recons are close enough to the low end Rebas performance wise that I doubt you’d notice. If you’re lookign 2nd hand it gets even more complicated as more modern and higher end Recons may even have the same damper as an older Reba.
Just be sure to check what Damper they are using and what spring type is, but generally they are good forks for the money that offer decent performance with only a mild weight penalty.
