My cycling brother from another mother bought himself a Postal Edition Trek 5200 and fitted it with 11-speed Ultegra components (looks like an 11/28 cassette with a 50/34 chainset). I’ve had my 5200, a few years older (his looks like a 2002), since 2012 so I’ve had a lot of time to tinker with it to make it into exactly the bike I want it. I’m here to tell you, if you want a good, workhorse frame to build into a new, racy steed, the 5200 is an excellent choice. It’s a little on the squishy side at the bottom bracket by today’s standards, but modern components work. You can get everything you need – 11 speed components, wheels, cranksets, headsets… and you don’t have to go expensive, either. I’ve got a budget Shimano crankset with SRAM chainrings and the 105 drivetrain that came off my Specialized Venge when I upgraded that to Ultegra. I think, if memory serves, I’ve got about $1,000 into upgrading all of the components and wheels – and that includes the $200 I plunked down to upgrade my Venge’s drivetrain – for the entire build (not including the paint job, however):
So here’s what you’ll need to know, generally, to build up a 5200, from the frame up. First, you’ve got a 68 mm English threaded bottom bracket (I’ve got an Ultegra BBR60 on mine that has been fantastic). I also have, and highly recommend, a Chris King 1″ threaded headset (for the pre-2000 5200’s). King’s headsets are known to be bomb-proof. You’ll have enough room at the back triangle for 10 or 11 speed components, so go nuts. For the wheels, you’ll want to be careful and keep the rim width to 23-mm max (25 will be a little too wide – I tried 25’s with 26 mm tires and there simply isn’t enough clearance at the chainstays – the tire will rub whilst climbing out of the saddle). For the seatpost, you’ll need a 27.2 mm. I went with a carbon fiber Easton model that I’ve had on there since ’14 or so. The old, original seat posts had slots to adjust the saddle nose up/down. I found my comfort zone to be exactly in between two slots. I needed/wanted something infinitely adjustable. I use a quill adapter so I can use a standard threadless stem. I’ve got a Bontrager Elite Blendr 90 mm x 17 degree (flipped, obviously). I specifically went with the 17 so I’d end up with the stem parallel to the top tube. Finally, to round out the new parts, I’ve got a sweet Bontrager Montrose Pro 138 mm carbon fiber saddle and a Bontrager Elite Aero alloy handlebar that I put on a couple of summers ago.
From the ground up, it’s an impressive build and I thoroughly enjoy riding it. It’s surprisingly light, too. I’m at 18-1/2 pounds as you see it in the photo above, but could go much lighter with Ultegra or Dura Ace components. While it’ll never measure up to modern race bikes, it’ll hold its own in any setting. I’ve heard it said that frame has more US wins on it than any frame in the history of cycling.
