first off profile makes great products, I have had my cranks for over 5 years and there still going strong, just got a new BB off ebay but thats the only thing i have changed, but i do think they need to update a little and make the spindle hole and sprocket bolt hole 1 piece, similiar to the stolen cranks
I love this lever, it's lasted quite a long time too. I also liked how it came with replacement bushings and bolts. The only downside is that i have a few freidns that "overtightend" theirs to the point where the brand new lever snapped. I haven't had any trouble though.
