I have been riding the BSD Revolution hub for a few months now. When I first got it, it would accidentally engage on me all the time (during rear wheel turbines it engaged all the time). I wanted to love the hub, but was really struggling with that. The lack of slack, the light weight, and how sturdy the hub felt was something that I wanted badly. Another guy that I ride with, who also has the BSD hub, has not had this happen to him. So, I had hope that it could be resolved.
I ended up writing back and forth with Tal Mazar (inventor) and BSD. Apparently, this has been reported by other riders. Though, they didn't really have much solution for me. For what it's worth, Tal is a super cool dude and was great about talking back and forth. It sounds like they're continuing to refine the hub. Does that mean a v2 will land? Who knows... But, it does seem like planetary is a 'game changer' in the hub world...since we see so many popping up now.
In a last ditch effort, I bought a brand new clutch mechanism. This was definitely not a cheap thing to try. But, I said 'whatever' and went for it. Since I've had the new clutch it has never accidentally engaged on me. The biggest difference that I noticed between the clutch discs was how easily the new one slid onto the axle. The original was a much tighter tolerance than the new one. Is that the only difference? I don't know. they look identical. Did I need to buy a new one? No, probably not. If I knew what I know now I would probably try to take some steel wool or something to the clutch that came with the hub and try to make it slide on more easily. Which I can still do since I have it.
Do I love the hub now? Yes, yes I do. I had been riding the Oddy Clutch (v1 and V2). While I do like that hub, I always had some 'slop' in the hub. I could grab my tire and push back and forth and feel a little side to side slop. I even tried replacing bearings. But the slop remained.
I think as time goes on and more and more riders try/switch to the planetary hubs they will probably figure stuff out/refine them. The only thing that I don't like about the planetary is that the pawls sometimes pop. It's such an un-nerving sound. It doesn't happen a ton. But, it does happen from time to time. Keeping the axle nuts super tight seems to help here...
Is this the perfect 'flatland' hub? That I don't know. It's super sturdy, smooth, and light. I almost wish that it had just a little bit of slack though (<= 15 degrees or so). I only ride flat and have no regrets with the hub...even if it didn't work perfectly out of the box.
That's been my BSD Planetary Hub adventure...
Ride on!
