spank hex hub

Hello,

 

My rear hub (hope pro 4) starts having problems. As i'm already old and don't want to die on a drop, i might change this hub and find alternative (seems common for hope hubs to have issues these last years  ...)

Industry nine is an option but very expensive.

I've seen the (quite new) Spank Hex hub, with 102 engagment points and a price tag similar to hope.  Anybody has tried it for trials? What do you think?

 

Thanks in advance.

D.

Only because there are so many of them in use, IMO.

Can't comment on the Spank hub, haven't seen one in real life.

I have the Spank hub, though not on my trials bike but on my mountain bike. And only when it's not in single speed mode, so I've ridden it only twice so far :D. I've opened it up, and it's your typical pawl hub with a few tweaks, basically the same as the Hope, but with more teeth on the drive ring and two more pawls. With the higher teeth count on the drive ring, and hence way smaller teeth, logic dictates it's more delicate than Hope. They've sort of tried to counter that by having pawls with three teeth on them, so the engagement area is a bit higher. They say all pawls always engage (hard to check if this is actually the case when under power), while with the Hope Trials hub it's half the pawls. No idea how this all stacks up, but I reckon the problems you're having with Hope, will develop on the Spank hub too eventually.

Btw, which issues are you having? Given the freehub a good cleaning and regrease/reoil with some light weight stuff?

Hey guys,

Thanks for the replies.

I might have a go and open the hub then..maybe I can see something then. I's not very old though (2021 inspired hex).

Since the beginning it sometimes "miss" an engagment making this awful noise. But now this is happeing more and more often, so it's getting scarry... Hopefully as i just start riding again after many years i don't go too big :)

I would advise against riding the bike until this issue is resolved as it will only further damage the hub.
I understand you've been running the hub for a year, so some wear and tear is to be expected. It is good practice to check our hubs every 6 months or so and I would replace the pawls and springs once a year to prevent failure. This information is from the guys at Tartybikes (guaranteed!). I hope it is useful mate.

I read somewhere that Yohan Triboulat suggests to be good alternative for I9 which is way expensive. Spank has good reputation,so this Hex hub would be my choise when my Hope 4 SS go to hell,just to try it out.People like him know to what they talk about. Unfortunately,I was not be able to find any review or whatever information related to this hub and trials use.Good luck.
