Ten on Seven

My colleague Jay Jackson just showed me something
interesting:

The new Dura-Ace 12-27 cassettes come with a 1 mm spacer
that is supposed to be used when they're installed on a
9-speed hub. (The bottom end is slightly recessed into the
spider.)

Jay tried installing one of these cassettes without the
spacer on a
N.O.S. 7-speed 105 hub we have in stock. He found that, by
substituting a "compact type" lockring, he was able
to successfully mount the 10-speed cassette on the
7-speed hub!

We haven't tried this on an actual bicycle yet, and it
looks as if chain clearance may be a wee bit skimpy on
both sides, but it looks as if this could be made to work
in som applications...so there's hope for folks with non-
ferrous 126 mm frames!

Well my fingers are crossed!

As an owner of a 979 Vitus this would be very good news..
it would also keep me from wondering about re-spaceing the
753 Bike...

My vitus 980 takes a 9-speed wheel easily; on a good day it
drops right in, and on a terrible day I must put a slight
amount of pressure on the dropouts.

My Trek 2000/1500 has no difficulty with a DuraAce 8/9 hub.
I lamented its inability to evolve for a couple of years and
then decided to try a wheel from another bike and it went in
with no real difficulty and has been working well for two
years. It started life with a 6 speed freewheel and is now 8
speed Ultegra. Some day it will inherit a faltering 9 speed.

My 1989 Trek 1400 (bonded aluminum), originally equipped
with a 105 7-speed hub, has been riding around with an
8-speed hub for almost four years now. I've been riding
it often lately. It takes a little outward pressure to
snap in the rear wheel, but other than that there have
been no problems.

After riding my Vitus 992 for a number of years I measured
the rear dropout spacing with the hub removed. It's 128mm.
The Vitus has apparently never cared that it's been holding
a 130mm hub. It's my primary bike and is now 12 years old.
