Svend I am perplexed by some of your statements.

On my Anthem X 29er

I either run

24/32/bash with a 11-36 10 speed cassette

or blank spot/32/bash with a 11/36 10 speed cassette

the bash takes the spot of the big ring

The 32 is where the 32 normally is. The middle rings chainline is such that it work with all of the rear cassette cogs well.

This is my Single speed but for all purposes involving this thread you can kinda of see how the bash is in place of the big ring. The front ring on my single speed is a 32 tooth like most middle rings. It also sit on the same chainline as a middle ring.



Jim I have no idea why you want a 12-27 cassette on your bike...... I am single speeder but for my rear cassette I see no reason not to have the largest spread of gears in the rear.  On my 26er I use to run 26/34/bash with a 11-34 9 speed cassette.

Basically what it comes down to if you want to start tackling log overs running a bash is nice thing to have and will make the learning curve less steep. '
