WTD: Part of a cassette

by Gkam84   May 28, 2013  

I know SOMEONE is going to have what I need....

I am looking for the big end of a 9 or 10 speed cassette. Ideally 36t but 34t would be fine. So the top 5/6 cogs that are held together?

Has anyone else designed their own cassette and only needed the small cogs and has the larger ones sitting doing nowt?

I'm replacing the 10 speed on my trike, but its so difficult to get ahold of and really expensive. I've decided to just put my own together.

I have coming a 9 speed Capreo that I will take the smaller cogs off and join them with the bigger end of another cassette.

So what do you have lying around, new or slightly used is fine. Big Grin

Mathew, The spacing difference between a 9 and 10 speed is that small it doesn't make any difference on my trike. http://sheldonbrown.com/cribsheet-spacing.html

Revo, I can't really go below 34, I have struggled up some hills on 30/34 already, so I know I need a large cog

Are we talking Velominati rules here??

Rule #5 // Harden The Fuck Up.

They do not apply to recumbents Wink If the UCI cannot allow recumbents to race anywhere under its rules. Then Velominati doesn't apply to me.

But you try pushing a 40lb trike up a 20% slope, you cannot just dance on the pedals, you can only keep spinning and once you start to lose traction....that's it

Because Shimano Capreo is only made in 9 speed. So you have to adapt it to 10 speed.

Unless you buy one of only two 10 speed aftermarket 10 speed Capreo's. One is priced at £180 (made for ICE) and the other is £122 (but its from Asia, so might get stung with import duty)

So going by what everyone else in the recumbent world does. They buy a 9 speed Capreo (£50) then get the top end from another 9 speed system and put them together into a 10 speed.

The reason being, that Capreo is specially designed for smaller wheel bikes. To give a better ratio.

You can only fit certain things onto Capreo hubs. The one ICE have designed fits SRAM/Shimano for the top up, upto 5 cogs and then you need Capreo for the other 5.

Its complicated Wink

jesus that sounds like some leg work!
we've done some trike & tri-andem builds before so if spares are needed at any point, gimme a shout.

(except the top end of a 10spd cassette!)

Its the top end of a 9 speed I'm after Wink

Its also a recumbent trike. So few places have anything I need. Although its mainly all standard parts.

I am on the look out for front disc hubs, but its also complicated. Have to be 100mm, 6 bolt, 36h with a 12 or 15mm thru axle
