Has anyone taken a file to clean up their Quickbeam or Simpleone track 
ends? I did, and it was a vast improvement after 14 years of hard use. 

I just got a Paul high flange wheelset and a Dura Ace crankset, and set my 
green Quickbeam up as a two-speed fixed gear again. The Paul hubs attach 
with bolts and fancy washers. The washers are sleeved to go inside the 
dropout, and I had the dickens of a time getting them to move smoothly down 
the length of the track end. Care-free gear changes wheel installation rely 
on easy axle movement. 

I inspected how the washers slide down the track without the wheel, and I 
found that they simply didn't. They'd go a bit, and catch, binding badly in 
a couple points. The edges of the track ends, especially at the bottom, 
were pretty ragged. In the center of each axle track (the inside part of 
the dropout), there's still green paint, as if the edges are higher than 
the centers. The edges were worn, rough, and scuffed. 

After a bit of hesitation, I took a sharp file to the top and bottom of 
each dropout's axle track. I filed as flat as I could, but the steel is 
very tough, and I didn't remove much material. I didn't even remove the 
paint inside the dropouts. I checked the free movement of the bolt washers 
several times, and cleaned up each tough spot. After about 15 minutes of 
filing and checking, the washers slid up and down the axle track pretty 
freely. I put the wheel back in, and sure enough, it was now very easy to 
set the chain tension, and switch between the high and low gears. On this 
two-speed "dingle" setup, you change gears by moving the axle forward, 
derailing the chain onto the little ring and big cog, then move the axle 
back to tighten. Before the dropout cleanup, this was frustrating, and the 
axle wanted to "index" into particular spots. After the cleanup, it was 
easy and kind of fun. 

So - Quickbeam track end cleanup is now on my 14-year maintenance cycle. 

Side note: The new 120mm Paul axle is hollow, aluminum, and relieved. It is 
111g lighter than the old steel 130mm solid axle! $40 to save a quarter of 
a pound seems justifiable.
