A customer brought in a first generation R-SYS rear wheel for me to work on.
Just the rear wheel.
It has Campagnolo 11-speed cogs on it,
but the customer said that when you tighten the lockring, it becomes fixed-gear.
It had been left with another shop for about six months,
during which time they consulted with and even sent it to a Mavic (the hub manufacturer) dealer,
but it was returned with the message that "we can't do anything more about this."
↑The first generation R-SYS has a shape like this,
but when you fit Campagnolo's 11-speed cogs, they contact the right flange.
The problem is that the cogs protrude inward beyond the end of the freebody.
Campagnolo didn't introduce 11-speed until 2009,
and the first generation R-SYS came out in 2008,
so it would have been impossible to anticipate this incompatibility—it can't be helped.
In this case, a thin spacer called an ED11 spacer should be inserted before the cogs,
but it wasn't there.
However, the ED11 spacer is so thin
that it alone won't solve this problem.
↑This is with the freebody removed.
The spot on the right flange where it was contacting the cogs isn't even dirty.
I think the fact that we can't fix this is "just the specification, so it can't be helped,"
but you can tell immediately that there's contact by just testing it against the low gear.
This really shouldn't have required six months of storage to diagnose.
For some reason, there were two anti-lockring spacers installed inside the freebody
when there should normally be just one.
I guess they were trying to gain clearance this way,
but even with two spacers the contact still happens, so the problem wasn't solved.
I really hope this wasn't the result of instructions or repair work from America Sports (the Mavic dealer),
but returning the wheel to the customer in this condition is wrong.
The customer didn't even know there were two spacers in there.
Even if the contact problem were somehow solved this way,
the derailleur adjustment would become "specific to this particular wheel."
What's more, I thought maybe they re-centered the wheel with two spacers installed,
but it was already pretty much centered with just one,
so what they had created was "a rear wheel that's one spacer thickness longer on the right side only."
Anyway, it's sorted now.
There's one spacer in the freebody—the standard configuration.
I cleaned up the cogs while I was at it.
It's true that the contact issue is "just the spec, can't be helped."
It's also true that standard methods can't fix it.
But taking six months to make that determination,
or returning it to the customer in a half-baked state (that doesn't even solve the problem)
just seems wrong.
Our shop doesn't have an ED11 spacer,
so please source one to cover the cost.
（The cogs aren't rubbing the flange in this current state.）
