Time to see how it "stacks up". First I used a bottom bracket washer and an 8 speed spacer to get the rings where they should be.





Here they are on the wheel, with a 28 in the 3rd place. As you can see the chainging bolts dont interfere with the chain on the 28 at all:





Here is the whole cassette. Its an 11-42 8 speed. Ya the gaps are HUGE, but I am willing to deal with that:





Here it is on the bike:













I havent had a chance to ride it yet, but on the stand it shifts pretty good. The 11-34 cogs are perfect, the 42 rubs a tiny bit on the upper derailer pulley. I need a longer screw on the back of the derailer. If it was 1/8 inch longer the derailer would totally clear the pulleys. A 38 or 40 tooth ring would probably not need this.


Total weight gain was about 80 grams. Once I know it works, ill lighten it up like I did my chainring...
