Is front suspension remote lockout worth it?
First off many forks have a remote lock out as an add on. Fox and rock shox especially. If it has a lock out, a remote lock out is likely available. 

Secondly, a nice fork that is set up properly for your weight shouldn't need to be locked out all that often. I have had a variety of great fox and rock shox forks that i only lock on long, steep, grueling climbs where I am standing and pumping. This was more needed on a single speed. If you plan to sit and spin up a hill you dont need the lock out at all. 

Out of the last 5 forks i have had, all had a lockout, but only one with the remote. While the remote is convenient, I have never found it difficult to reach down and lock out on the fork while riding.
