I don't know exactly. I am fat, heavy, noob.... Highest drop honestly is just 4 feet. pedal kick is only a meter, can't sidehop above 3 feet.... I don't know, really....

What are you doing to kill all these freehubs!?! What hub was it this time?

Best hub I've had since getting back into street trials a couple years ago is the TMS, it's a bit draggy but not skipped once and decent engagement.

I'm running an I9 just now and it skips every so often, I might actually sell it and built up my TMS hub again.

Got some specs and a price for the i9 please

If this refers to gapping: Some say that it's about moving forward and upward, not kicking the drivetrain. I improved my width a lot when I made that change decades ago. Friend of mine (>300 cm, unlike my measly hops) says that he only adjusts the pedal position forward during the jump, to retain a good platform to push against. Squatting on the rear wheel also helped me.

I came from freewheel too.... I had nightmare removing it on the cranks for replacement. So I moved on....

Go for a Hashtagg freewheel then.
One requires the ISIS tool to remove them:

Alternative, find a fixed hub with spline body or a crankset like the bonz one:

I think using the Hashtagg freewheel makes more sense for you, it will be easier to fix compare to the bonz freewheel.
If you want, I have a new Tensile freewheel to sell that also use the ISIS tool. It has only 60 POE. I will be happy to sell it to you.

My pedal kick honestly is somewhat weird to see or maybe. I stopped doing gaps straight front, usually diagonal or sideways since the first time i stripped my hub and landed nuts over the stem. Or maybe I need to imrove my gaps more, it is just heartbreaking to break parts which impacts my pocket and enjoyment....

In the last 20 years, I broke just one freehub on my city bike (bought in 2000, cracked in 2021). I weigh 70ish. There has to be some detail in your gap technique that kills them. Or do you have some special dust or sand that clogs the pawls where you live or something? Like that fine Oz outback sand that gets through seals like it's nothing, I mean.

Mind posting a clip of you or at least your cranks when doing a gap?

Must be a "bitch crank" issue. If it's not, then I don't think it can be an user error in any other way.
If you preload a big amount suddenly and kick very aggressively without letting the hub engage first. Sharp impact with momentum is likely the reason, not power. We see hugely powerful riders using these hubs without constant issues, but they are smooth as.

In fact I've been struggling with similar issue for years, since I originally learnt gapping with way too much preload/kicking with the front foot instead of shooting forwards with my body and trying to be more equal with my feet. It's really hard to get rid of that unwanted muscle memory and I still occasionally struggle with that. Often when I try to put all my power on something, the front foot unconsciously lifts way too high. But my hubs have been doing relatively well though, if not counting those faulty products that everyone else is having problems with too.

Didn't see a massive issue in that particular video, but it came a bit more apparent from the other videos on your channel. There definitely is some "hammering" effect or last minute kicking, if you know what I mean. And you seem like a fairly strong guy so that might be it + bad luck with the parts.

Probably try learning to jump more with the body and less with the pedal kick. If you watch pro competition riders they barely lift the front foot when they gap (some small pedal kicks or preloading for drops are different thing). For gaps, they have already preloaded their cranks a bit before the actual preload for the jump which happens with the body. And their ankles/calves do a lot of job, almost equally on both legs. Much easier said than done, I know.. 😃

A good way to practice would be taking off from a ledge or something. So you kind of have to keep the pedals fairly level, or the rear wheel rotates too much and slips off before you get any power down for the gap. As an extreme example, rail gaps or stuff like that don't really allow much wheel rotation.

I am still trying to figure out how to time precisely doing gaps on a ledge. And I still have in my mind that multiple incidents where I gap on ledge with pefect chain breaks.....  I will do try to improve my ways.....

By the way, EXTENTION just sent me 2 pieces of freehub for free.... Seems glorious yet I am curious....


Thanks for the inputs guys!
