Last Sunday I went for a ride at my usually trail. There are 5 major hills which are steep, somewhat eroded and what not. Ive ridden it many times and usually I can climb 1 of the 5 hills before i get rear wheel slippage or just get too burnt out.
THis time I decided to put my ETA adjustement (locks the fork down) to good use seeing that i rarely use it. Lemme tell you, I was hammering those hills. I was putting my friends using clipless to shame (I ride on platforms and only platforms). I just got some much more power transfered to the rear wheel. So of the 5 hills, I was able to climb every single one of them.
THe only problem is the switch is right by the leg of the fork and it could get dangerous when I am locking it on/off. I loose concentration when trying to flip the switch. I am in the process of trying to get one of my old thumbshifters to link up with that switch to make a remote lever. Still in the early planning stages.
If you have lock out....USE IT!
it might make a big difference in your climbing abilities.
