We carry both the Cascade one and another style ($5.00 cheaper, have to adjust from the backside). They both work good and hold up well. Guys its really not that hard to adjust the cheaper one and its only a one time and your done deal. BUT, if you have never done it the Cascade style might be easier. Kevin , if you want, call me in the morning and i will explain this all to you better if you dont understand. We keep everything you could possible need to get it setup correctly .
FYI, Dont know which it is on that ebay link above but beware of pancake bearings made from aluminum (which it looks like it could be) as i have seen them wear very quickly!
