For $350 you have done well.
If your hubs striped look at the quality of your cog and lock ring and check their on right and tight in the future.
more than likely its one of these not the hub almost every one has had formula hubs at some stage.
Their not bad but if like my old Alex wheels they are the non sealed version.
I reckon formula hubs are great. I’ve gone from a set of phils to a new build with open pros to formulas and am very content.
My first fixed gear ran deep vs to formulas and I still rock that bike nearly every day and it gets beat. I couldn’t recommend formulas more and think that at the price they go for, you can’t go past them.
Had a set of these wheels and they were great bang for buck. Aside from being loose ball bearings and needing to be dissassembled/repacked from delivery(little to no grease), they were fine.
The sealed are much better than the non sealed in the formulas though.
My non sealed where pretty slow and not real precise .
Bang for buck still ok though.
Some people claim to have stripped their thread but turns out they just don’t know how to put the cog and lockring on properly.
Scored a mad wheel for $50 back in the day, the guy tightened the cog and lockring by hand then when he started riding the cog tightened a little more. When he would skid it would unwind that little bit back and hit the lockring, he thought ‘oh no my hub is stripped better get rid of it’ all I had to do was tighten the lockring and it was fine.
If you genuinely stripped a thread you must have done something pretty strange when installing it
i had it installed at a lbs, the best known in the area for fixed gear, but the lockring must have come loose somehow, because i had that problem where the cog unwinds and hits the lockring, it only happened on a big skid, i never had a lockring tool or was too lazy to ride to a lbs.
eventually the left hand thread on the hub was gone.
