Does anyone run their 109 with the non-adjustable 103 front end? I run on a large-ish parking lot track w/ silvercan. Seems like the extra adjustability is just more complexity (and more to break) than necessary.
My plastic castor block is broken, and I find myself debating over whether to get the aluminum upgrade, or switch over to the simpler 103 front end. The guys running 103's seems to be doing pretty great with it.
