Cassette spacers

ReductiMat · 07-31-2012, 03:54 AM

If I wanted to pull out a few cogs in the cassette, can I just use a various amount of spare cassette cog spacers? Or is there something more to it that I don't know about?

I don't see why you couldn't remove cogs in sequence from either the bottom or top of the of range and simply re-adjust the throw screws on the derailleur.

Might be tough to teach your derailleur to skip a gap in the middle though...........

I'm pretty sure you can. I think Matt D's friends had a three or/and five speed cassettes made from nine speed cassettes with the bigger rings taken off and replaced with spacers when I saw them riding. If that's what you could PM him as he probably knows for sure.

Yes, you can remove cogs and use spacers to replace the pieces you removed.

Wait, what!? How do you get from the smallest to the next smallest cog there?

Can't I just smush them together and bring the most spoke-ward cog toward the axlebolt, and put the spacers against the spoke-side?

(My vocabulary there is top-notch no doubt)

I doin't think he's using that 12 or 11 cog. But you need that to clamp it all tight. That last position cog goes over the end of the freehub body and has splines that mesh with the lock ring which I don't think is large enough to clamp just spacers. And yes you can spacer up just the inside to get what you want. Adjust the limit screws accordingly.

Mr. Oldfart is correct. The last cog was not being used (I hadn't yet ground off the teeth.

To answer your question "Can't I just smush them together and bring the most spoke-ward cog toward the axlebolt, and put the spacers against the spoke-side?"

Yes you can just put spacers against the spoke side of the freewheel and have all the cogs on the outside. I did not do that because I wanted to center the chain on the 5 gears and keep a dead straight chain line. It was a waste of time but I proved to myself that it could be done.

some seasons back, I bought a Shimano 9 speed road cassette for my Banshee Rampant and removed the bottom 4 cogs to make a 5 speed cassette

then did the "Aaron Chase" conversion of running a set of same diameter spacers (all nylon) to replace these missing 4 cogs, and set the limit screws on the rear mech, so that the mech would not overshift the chain into the inside of the dropout face when I shifted off the 5 cogs

this allowed me to effectively freecoast my Rampant(like on a BMX) backwards as the chain when shifted off the 5th cog would end up on the nylon spacers and freely slide so I could roll backwards without the pedals rotating

to get back "into gear" you simply shifted the mech and it would re-engage the first of the 5 cogs

I experimented and started incorporating freecoaster tricks into my pump track riding

I would fakie bunnyhop on the 1/4 pipe, roll out backwards and then pump the track backwards before 180 hopping off a big bump, landing forwards, shifting back "into gear" ready for whenever I needed to pedal again

also looked at taking this to drops, and experimented with rolling fakie off a drop (ladder) and then 180 hop to land forwards, but very difficult on a MTB (I was riding this kind of stuff on BMX at same time) to stick the landing and not get ejected...

always thought it would have blown minds at an event like Crankworx to 180 onto a ladder / ramp, roll fakie off a drop and 180 hop and land forward (like the awe of Bearclaw's 360s at Whistler Crankworx those years back..)

I was going to ask why... but hamstead bandit answered it.

I'm sure that's why the OP wants to do it. Fakey take offs.
