New for 2001 (not)<br />
The 520 is a <strong>Trek</strong> classic. We’ve been making this<br />
frame for quite a few years, and wouldn’t dare change<br />
it. In the world of bike touring, this is a very refined<br />
design.<br />
Geometry<br />
The 520 has true long distance, self-supported touring<br />
geometry. It is very stable, with relaxed steering that<br />
feels just right when the bike is fully loaded. It has a<br />
low bottom bracket to keep the center of gravity low,<br />
and also to make it easier to mount the bike. Very long<br />
chainstays provide lots of room for a rack and panniers,<br />
without compromising heel clearance.<br />
Ride<br />
Thanks to the true long-distance design of the 520,<br />
it’s very comfortable and stable. While it fits the classic<br />
touring mold, we use slightly larger diameter frame<br />
tubes than the bikes we built in the 70’s. This makes<br />
the 520 more stable when fully loaded, when some bikes<br />
get ‘whippy’.<br />
Frame details<br />
The 520 has all the amenities of a true tourer. It has<br />
full braze-ons for 3 water bottles, front and rear racks,<br />
and even fenders. Cantilever posts allow the use of more<br />
powerful brakes, which provide a very comforting feeling<br />
if you are sitting on a fully loaded bike at the top<br />
of a long hill.<br />
