Hope 6sp Proto Cassette
- Thread starter Trekrules
- Start date
profile makes a 6spd hub. never seen it in person 
I was thinking the same thing
Cardboard, huh....I bet it wears out fast but people will buy it anyway because it is light. Not sure how it will work in wet conditions though.
does it have the pawls built onto it like the last proto they showed?
where does it leak oil from?
That's what I was wondering. If Hadley did this I'd be stoked. The hope hubs need MOAR PAWLZ!!!
Dont be silly its not a Land-Rover.
Or a Harley..............
But cereally, the cassette looks kewl, when they make one out of metal not recyled egg-crate.

For downhill? It's not like engagement points are really a big deal on a DH bike. Maybe I'm just too fat to care much about pedalling but I can't say I've ever thought "gee this lack of engagement points is annoying" mid run, which I can say about almost every other thing on my bike at some point or another!
Yeah but so is filing your fork crowns down for better aerodynamics... reality is that there is a million other things you could worry about first that make a far bigger difference.
I will say there is a huge difference between the shiimano 17* engagement and the more modern 26* found in hopes and most formula knockoffs. It's immediately noticeable on a trail bike and should be on a DH as well. As far as 72 vs. 36 vs. 26, I don't know.... But it's definitely worth buying a DECENT hub, whatever the engagement, IMHO.
the one thing i'll chime in about here was when i went from hadleys to a hub with less engagement points, my balance was thrown off in some sections because of how long the lag is before the pedals engages...this was more of a problem in slow speed techy sections....there's a definite advantage there, no question
Hope already sells hubs with 48 engagement points, the Pro 2 singlespeed/6-speed/trials version. Still 4 pawls but only 2 engaged at a time. With steel freehub.
And it sounds like an angry swarm of killer bees.
Hope already has axle issues. More engagement points would = a higher chance of partial pawl engagement = more chances to shear an axle.
They need to address that issue first.
Eh?
1) The axle issues HAVE been addressed with the pro 2 evo.
2) Not sure how one could ever get "partial" pawl engagement, unless there was something already faulty in the hub. A damaged spring, excessively thick grease etc.
3) Even if "partial engagement" were to occur, I can't see how it would lead to axle failure. Damaged pawls/ratchet ring, sure, but none of the drive loads are carried by the axle.
They did. They addressed that issue by removing the 17 to 15mm step in outer diameter of the axle between hub body bearing and freehub.
All I can say is, that I'm riding my Hope Hubs on my DH bike since 3 years, and they're still fine.
Only thing I did was to regrease the freehub last year, and thats it. Even the original bearings are still running...

No freehub body can ever be produced so that all the pawls are perfectly evenly spaced. They can be close, but they can't be perfect. The next time you have your wheel off the bike try turning the freehub body very, very slowly. You will be able to hear the distinct clicks. Once in a blue pedal kick you will engage at exactly the wrong angle and only catch 1 or 2 of the 3 pawls. This creates an enormous shear load on the axle between the freehub body and the hub shell. Depending on the cog size it can be several times the load on the chain.
Before you tell me I'm a kook. I worked for a wheel manufacturer for a few years in the warranty dept. I've seen it.
The only way to completely eliminate the risk of a broken axle is to go with a different engagement system or design the hub so that it can withstand single-pawl operation.
woody, you're still a kook

Don't go to sleep too early this weekend.
I always go to sleep early, I'm an old man.
Maybe he'll forget to take off his shoes...
