Today I look at installing an 11 speed Shimano cassette on a ten-speed freehub.
Last week I picked up at a LeMond Revolution trainer. This is our third
that we own. I had to pick it up it was a $175
These things, if you can find them in stores are over $800
Australian. So $175 I jumped on it. The problem being is it was ten speed.
I needed it to be eleven speed. The new 1.1 version of the LeMond
trainer comes out with an 11 speed free hub. But the one I bought the 1.0 only
had the tennspeed free hub. The solution from LaMond is to buy an extra
conversion kit which is about US$139 dollars or Canadian or Australian.
I could only find them on obscure websites and the shipping is an
absolute killer. So I was stuck with a ten-speed Lemond.
Now when the conversion kit costs as much as the trainer itself that's not a good
solution for me. So a few web searches and a few different solutions that I've
looked into we've come up with one that may work. There's a few different ways
you can skin this cat but what I wanted was no compromise. I didn't want to take
one spacer out or one cog out and have a 10/11. I wanted it fully 11 speed
compatible. So here's the theory behind the solution we went with. That there is
the freehub off the Lamond. It's a ten-speed free hub. So I'll draw
it one of those. Not just scale but we have a ten-speed free hub here and we'll
draw a 10-speed cassette one, two, three, four, five, six, seven, eight, nine, ten. The
11 was a bit small. Okay so 10 speed 10 speed. 11 speed same deal.
Well almost the same deal. Axle through here. One, two, three, four, five, six, seven,
eight, nine, ten. Little cog 11. Into the measurements the distance between here
and here is 34.95mm. The distance between here and here
on the 11 speed free hub is 36.75mm.
So compatibility wise is a given 10 speed goes onto 10 speed. 11 speed goes
onto 11 speed. Aha! And we can put a 10-speed cassette
on an 11 speed free hub using.....wait for it. 1.8mm shim because
that's the difference between those two there. There's 1.8mm difference.
So this is all pretty straightforward but I wanted this eleven
speed cassette on the ten speed freehub. And herein lies my problem. There's not
enough space on here to put this cassette. The two options we had are to
knock the back off the freehub body by 1.8mm. But if you can see
there there's not 1.8mm we can really shave off that that leaves us
0.2mm that's not an option. And the second option is to knock
1.8mm out of the back of the cassette here, so the eleven speed will
slide further in back over the freehub and it will be compatible. This one did
require some expertise so off to see the man Raoul Luescher. Our options are to knock off
the back off the freehub or knock off the back of the cassette. What do you think
is the best option? Yeah I mean ideal would be to take it
off the cassette body so you're not having to grind cassettes every time you
need to replace it. But how often are you going to be
replacing cassette? Not a lot. Not very often. Especially the big dog. How
often you really in that in that in those clogs on the trainer? Not, well
not on this trainer at all. We just need this thing to sit in place.
It's probably going to be simpler just to machine this guy. Then
even if you wear at the teeth on the on the cassette. You know once you can still
use this guy. I didn't even think of that! Brilliant! Yeah! Just keep you're using
this guy instead of, you know, a new one of these.
You're never gong to wear out these cogs on the Lemond trainer. It's all about
speed. You know you'd be in the 14 or 15 (cog)
most of the time on one of those. .... Take off 1.8mm
So there we have it, the finished product. We've knocked off about 1.8mm. From the inside of
that. Which is the same as the shim which we don't need anymore.
And we have the solution for my old school Lemond freehub. All right. Thanks
so much Raoul again for your expertise. I'm sure it's gonna help a lot more
people than just me. So thank you. (No worries easy done) Now for the fun part, let's put these on the
trainer and see if it has actually solved the problem.
So there we have it. Problem solved. I love this one because it was cheap and
it was very very cost effective. So I now have full 11 speed compatibility on my
"it was only ten speed" LeMond trainer. This also works as a solution for other
wheel sets as well but it depends on the spacing you've got between your spokes
and your rear derailleur so your mileage may vary on this. So there we have it
happy days thanks again to Raoul for ease assistance with that and I think
I've got to go buy myself a lathe. I've got a few other projects coming up.
