I had problems with a 1999 Specialized mountain bike where an excessively hard and smooth mech hanger, which formed the inside if the dropout, not adequately gripping the end of the hub after I switched the back wheel to a shimano hub. I had a bent axle as a result. I wonder if this is similar?
edit: on reflection, bent axle may have caused slippage rather than vice versa. I still felt the hanger was too hard to grip properly.
I think it should have been recalled purely on the fact it is such an ugly bike
This si simply a case of a poorly designed replacable dropout. Easily solved. I would second the call in general though for through axles. Nobody short of a pro-racer needs to remove a back wheel quicker than it takes with these, been on mountain bikes for years, infinitely superior.
Totally agree and with the increase in road bikes with through axels I suspect they will be the norm within a couple of years.
Another reason why we need disc brakes and thru axles bwahaha
Not necessarily, typically your skewer will jump out when you've got a lot of twisting force through it, that could be climbing out of the saddle (I'm which case bad) but could be the first turn of the pedals as you pull away from a traffic light. If it's the second then the likely result is the tyre hitting the chain stay and the bike stopping.
Sure, I'd be grumpy but it's not a frame destroyer or a crash hazard in that case. Wonder how they messed up...
I don't really understand how changing the hanger would prevent a wheel slipping out of the dropouts. Could anyone explain?
A complete guess but if the hanger forms the outside of the drop out then it could be that they made it nice and shiny and then forgot to build in lawyer tabs.
Rear frames don't usually have the lawyer tabs (only on the front forks) so whilst they could add them (to a hanger forming the dropout, to reduce the risk of a wheel release) it would be sticky plaster solution and an attempt to avoid entirely replacing a poorly designed frame.
I think they need to explain precisely how the hanger replacement resolves the issue to the owners so they regain some trust that it is a valid solution to a dangerous problem.
I would imagine the problem is that the exit angle of the dropout is not forwards-facing enough, allowing the wheel to slowly creep backwards as it hits bumps, etc and ultimately pushing it out of the frame. One would hope the new hanger has a "less open" design with a more acute angle meaning the wheel has to be knocked forwards to drop out of the frame. If the issue is just on the drive side then it would match the description of the wheel coming out (marginally ahead on the drive side) and then snapping the frame (on the non-driveside at the drop out )
Come on Specialized, let's be a bit more honest here. The second part of the sentence should read something like "a rider will lose control and have his shit ruined"
