I'm going back to Park City in a few weeks and there are some insane 20% + grades there. I have a 11-32 cassette for that, but hate the gaps. When I saw that Shimano is now making an 14-28 Ultegra 11 speed cassette, I looked at the parts and realized I could build the cassette of my dreams, the 14-32.

Before you get started you'll need a few things.

An 11-32 11 speed cassette
An 11-23 11 speed cassette
A 14-28 11 speed cassette
A 1mm cassette spacer like the kind you put behind a 10 speed cassette on an older 10 speed wheel.
Some .005 brass shim stock from your local hobby shop
Some sturdy scissors

Use a Sharpie and trace the 1 mm spacer onto the brass six times.

Brass is soft and you will be able to easily cut it with kitchen shears. Cut on the outside of the outer black line cut out six circles.

Now, just make a single cut to the middle and then cut on the outer side of the inner black line. This doesn't have to be perfect as you will see later. The brass will curl up as you cut it. No problem, just flatten it out a bit when you are done.

You should end up with six .005 shims about the size of a 1mm cassette spacer.

Now, Put on the 25-28-32 carrier from the 11-32 cassette onto your freehub.

Then, gently arrange the shims around the freehub and stagger the gaps around 1/6 of a turn or so. Once again, it doesn't really have to be perfect.

Put on the 19-21-23 carrier from your 11-23 cassette.

Finish up with the 18, 17, 16, 15, and 14 cogs from the 14-28 cassette stacking these normally using the standard 11s spacers. Note that the 14 and 15 of this set lock into each other, so make sure it all lines up correctly.

Put on the lock ring and torque to 40Nm as directed by Shimano documents.

Use a spare 11s spacer as a feeler gauge and make sure the gap between the two triple carriers is about the same as the rest of the stack.

Go climb a brick wall!

FYI, you can use loose flat cogs from 10 speed Tiagra cassettes for 11 speed to get your 19-21-23 if you have enough 11 speed spacers. The difference is in spacer width, not cog width.

..........ok

Wested

I did not even realize they made an 11-speed 11-23 cassette.

It's Ultegra/DA level and appears it's being discontinued next generation.

Wow.....now you can do exactly what I was doing 40 years ago.......

Funny, back in May you said that 50/34 x 11-28 was for babies and grandmothers. What changed?

This is just for Guardsman's pass, 8.5% grade for several miles, several 15-20% sections. Otherwise it's 11-25 all the way.
If you need a 32 for less than that, you are a still a baby.

I think I'll just keep my 30 tooth small ring with my 11-28 cassette...

How convenient

andr0id

2-1/2 hours of up, 1/2 hour of down.
Kinda got cheated. First, the road from Midway to Guardsman was closed because they're resurfacing it, so I did the Big Cottonwood Canyon climb instead.
On the way down, there was a killer headwind coming up the canyon, so top speed was limited. Still really fun and the roads all have great surfaces on them, so no fear about potholes and craters.
Yes, used the 32 sometimes and for the last 1-1/2 miles which was 12% grade. Did a lot of riding 34x28 and 34x25.

Is it possible to make a useful cassette out of the leftover parts?

You assembled cassettes with 11 cogs 40 years ago?
