Swingarms from the different models
Posted: Fri Aug 14, 2009 2:27 pm
Today, I was mostly contemplating what swing arm to put on my bike 
I have a H1 subframe arm
I have a H2 broad beam arm
But both use a different size spindle
Looking at the needle bearing they are identical across the H1 , H2 and L models but the L arm has a modification with an additional set of bearings.
So I measured up the two H arms and swapping the internals about you are able to make either one interchangeable.
I also have an L arm hidden some where and although I already believe it would be impossible to make it fit an H1 ( without having a reducing sleeve made to fit all the way through) it just might go into the H2 without problem.
If I go for the broad beam arm then i will more than likely go for the L model as there will have been a reason to give it extra bearings , probably to do with flex in bends. So more to follow !
You can see here the differences between the H1 and H2 arm, note the spindle tube is the same diameter and length as each other . All arms also use the same chain guard which is a bonus as i have a new one somewhere too
