Well, as I understand it (and I may well be wrong) the trials version has two pairs of pawls, ofset from one another, so the rotation to engagement is halved compared to the regular version. However, the flipside to this is that, ultimately, the hub cannot handle as much torque. You may laugh, but over time, this has been the demise of my Bulb, (although rumour has it Hope will replace the ratchet when I actually get round to contacting them. They're an awesome company to deal with, so I'm confident of this fact).

With the deeper ratchet compared to the bulb, I'd guess you could expect similar lifetimes (few years) from the trials pro 2 providing you look after it and monitor the condition of the pawls.

I'm sure if you contact Hope they will advise you of this though.

anyone got any idea how to get the driveside spacer off?? so i can convert it?
