    New question here. Crunch goes Hope?

    Crunch, screech, clunk, bzzzzzz.....

    That's what my Hope Pro 2 SS hub sounded like at mile 60 during the Mohican 100 a few weeks ago. I was standing on a hill cranking and the free hub mechanism failed somehow.

    I was able to finish the race (with significant drag in the freehub body) but it got me to wondering. I'm a bigger guy , in the 210 range and I train for riding bikes using Crossfit. I train dead lifts, sqauts, etc. I can put a lot of power through the drive train and regularly do during short steep climbs.

    The guy at the bike shop said Hope free hubs occasionally do that. Given the reputation of the hubs, that surprised me. Anyone else have similar issues?

    I'll be going to the shop tomorrow to pick up the rear wheel and I plan to find out exactly what the failure was.

    I hear some have had a pawl or spring break in Hope hubs. Pull the freehub and see if that is the case with yours. I bought a set of pawls and springs just in case but have not needed them in a few years of riding.

    What kind of maintenance have you been doing to that freehub? Curious. I was going to possibly build up a set of wheels with it.

    I pulled it apart when I got it to see how it worked. That was two years ago now. I also pulled it apart at the beginning of the season and it looked essentially new. So, no actual maintenance, just inspection.

    I just remembered that the freehub would shift around on the axle, so I'm not sure if the pawls are the culprit.

    I dropped the wheel off at my LBS because I don't have time to mess with it . I'll find out what failed when I pick it up this weekend.

    So far, my maintenance has consisted of pulling off the freehub, taking the springs and pawls off, cleaning, re-greasing and putting it back together. I think I've done it about once a year.

    Probably, the bearings have to be replaced at some point.

    Hope has a thorough video about it on youtube:

    Well, I am happy to hear that your hub was about 2 yrs old when this happened. My hubs only have about 300 miles on them if that so far! Long ways to go for me (I hope). But I will probably tear them apart over the winter and inspect/lube them up then.

    Hopes are known to be the most economical hub for big,powerful guys. They have had some failures though. I'm surprised to see this in the SS forum though because SS hubs don't see near as much torque as a geared bike. For ultimate durability, you can't go wrong with a DT Swiss star ratchet hub or a chris king.

    I'm a big guy and can destroy a shimano freehub by looking at it. My DT Swiss 440 rear hub has been holding up well going on two years on my geared bike.

    Have you actually measured? I think it's very unlikely a geared hub see more torque, if anything my legs tell me is true.

    Mechanical advantage, you can pedal easier in a lower gear because the gearing is multiplying the torque from the pedals to the rear hub.

    Yep...

    I actually did some calculations of this on a recent plane trip....

    Force on the pedals, crank and chain tends to be higher on the singlespeed (your legs should tell you this). Force on the hub is exactly equal between gears and a SS for a constant speed and grade. Maximum possible force at the rear hub is higher with gears (unless you run a 22:36 front:rear or something silly) due to the mechanical advantage.

    That's why I was surprised at the hub failure. If the guts of the hub can stand big guys with gears cranking up stuff, they *should* be able to handle me on a singlespeed.

    The hopes are overrated from my research. Better than taiwan crap but not by much. I have read about failed shells, springs, pawls, bearings, freehubs, you name it. Its a quite cheap hub, and you get what you pay for (somewhat). Also the pawls and springs will definitely break sooner or later with all hubs of similar construction. The impression I have gotten from Hope hubs is that they are like midrange quality, nothing special, BUT all spares are available. Definitely one step behind the top notch brands.

    I don't have to. I own the hubs and they have been fantastic.

    Definetely makes sense to me now. But I still think ss hubs can see higher torque more often on Mtn bikes. Locally we typically climb quite a bit faster than gears. All goes out the window with a faster gear rider though.

    I'm guessing one of the bearings in the freehub body. Thanks for reminding me to do some preventative maintenance

    Talked to the shop today..... Not good news.

    Apparently I trashed one of the bearings and in the process of finishing the race I was in, I mangled the axle bad enough that it doesn't play nice with the new bearings..... I'm not too upset because I knew it was a risk when I made the decision to press on for the last third of the race. Just a bummer that the shop didn't catch of until reassembling the hub.

    I guess that means I have another week on the road bike before I can go play in the dirt again. There's worse things in life. I I get really bored I might build up my new cyclocross frame
