custom cassette?
I need a good tip. I need a new cassette for my racing recumbent bike. Its coming from the netherlands, so the flatlanders have a silly 12-25 cassette. The problem is that being a racer, I have to have the 11 and 12 tooth cogs, and at the same time, I use the bike for fast touring, and hit some 12% grades, I need a bailout gear of either 32 or 34 teeth. I preference would be to have the 11-12 on one end, and a 28-34 as my two largest teeth. That way I can have the majority of my cluster right in the middle where I need it, with a solid bailout. Problem is, I can't find such a cassette on the market - road clusters don't go that high, and mountain clusters are too evenly spaced.
Is there a cassette made, or a company that can put together, such a thing? Thanks!

My hybrid came with an 8 speed 11-32 cassette, with 11-12 on top and 26-32 on the bottom. It's a SRAM PG830. Pretty low end, but it might be worth checking out the rest of their line.

If you avoid the higher priced ones, a cassette is just a bunch of cogs and spacers bolted or riveted together. Just buy a couple of cassettes that have the particular cogs that you want and piece together your own.

Be careful though. Sometimes the rear 5-6 sprockets (depending on what speed you're using) are riveted together in such a way that separating them is nigh impossible. It's like one solid unit.
Others have screws holding them together, which makes it easier to disassemble. Funny thing is, it's generally the more expensive ones that are easy to disassemble.

However, if you plan to try a previous idea mentioned in this thread about effectively taking two cassettes and shuffling them together...on some of those the rear 5 will not be possible to take apart.
