Hope Hub - mod for 48 poe

[mykel]

The monkeys are playing in the workshop again....

Hope Pro II 150x12 48pt - a little mod

Would be nice if somebody could make up a batch of these for a bit of testing...

Thoughts from the Empty-Beer crew?

This looks interesting, I'd like to hear from folks trying it. I just got a wheelset with Hopes and 48 points would be killer.

The SS/Trials hub uses the same 24-tooth machining in the FHB and the same offset engagement concept to get to 48 POE... it just does it via offset machining of the pawl receptacles in the FHB.
I'll be surprised if it holds up to geared riding. My SS/Trials hub is showing distortion in the FHB cuz I put down the MONSTER POWER!! Geared drive trains have the capability to put substantially higher torque to the hub. There's a reason Hope put four pawls in that hub... he's knocked it down to two and I'm skeptical of the long-term durability. Dramatically increasing the angle that that the pawl engages the FHB puts additional stress on all the parts. Gotta give him props for the reasoning and motivation to get there though. Maybe it works just fine...

Thanks! How hard of a job is this for a mechanically included guy with limited hub experience? Do I just replace the free hub?

Hadley does 2 x 2 offset pawls on their 72 poe hubs and they have a solid reputation. Doesn't mean it will work with the Hope (though as stated their SS hub uses this configuration but with a shorter FH body) but it can work if done right.
