I’ve got RP23s on both a Banshee Spitfire and a Giant Anthem Advanced. The Spitfire I can’t tell if it’s on or off so I just leave it off. Or on, which ever way the elver is when I get it out of the car. On the Anthem you can tell the difference when climbing a bit and a bit more when standing up. Generally I can’t be bothered messing about with it, so I’ll leave it on or off during a ride depending on what the descents are like, tame xc stuff and PP stays on, wilder decents and I’ll knock it off. I probably shouldn’t really be ragging the poor thing anyway!
Thing is though, I would much prefer a lock-out with blow-off on both bikes. The Anthem forks have lock-out rather than a variable compression tune system, so if I set both ends for their ‘best’ climbing ability and stand up, the front stays solid and the back end bobs a bit, so the whole bike pivots around the front wheel axle. Which is pretty rubbish. If the back locked out it would be perfect. Or at least matched. I’d honestly have no preference whether the forks were changed or the rear shock, so long as the bike was balanced. This is a bike that was over £4k new, so these sorts of niggles shouldn’t really happen I don’t think.
So, the RP23 has 3 settings of PP, none of which are a lock out and two of which don’t actually appear to have much use. Would be much better if position 3 was a lock out, 2 was a bit firmer than three is and 1 was half way in between. Actually, they should make an RP4 that has off – a bit – a lot – lock on a 4 position lever with remote actuation. That would be much better.
