    Trek 3700.2

    I re-entered bicycling in 2005 with a Trek 3700. It was a fine entry level bike but its shortcomings quickly became apparent. I eventually built up some road bikes and upgraded to a nicer mountain bike, so the Trek sat in a corner of the garage collecting dust.

    My 20 y.o. son wanted to join me for some MTB rides. With his college tuition a new MTB is not in the budget, so I undertook a rebuild project on the Trek.

    I scoured LBS clearance bins, Nashbar, and Universal Cycles. Ultimately I spent about $400 on the build. This seems like a lot for a bike that only cost $275 brand new, but some of the cost covered maintenance items. I could have maybe gotten $100-125 for the 3700 on Craigslist, and I don't think a $525 new bike would be any better than what I built.

    Upgrades:

    Dimension rigid fork, Cane Creek 10 headset
    Clarke hydraulic disk brakes
    Disk brake adapter from Trek
    Deore/Sun wheelset
    SRAM PG950 cassette I had laying around
    Deore 9-spd rear derailleur and shifters
    Origin8 handlebar and some stem I had lying around
    Specialized The Captain Control tires

    By far the best upgrade was replacing the boat anchor RST fork. At some point I'll replace the original crankset, too.

    We took the Trek "3700 ver. 2" for an inaugural ride on McKenzie River Trail a couple of weeks ago. My son and I switched bikes at one point and while the fully-rigid Trek 26er is a bit more "lively" on rooty terrain than my air-forked 29er, it gets the job done.

    Axle to crown

    Sorry to open up an old post but hopefully your still out there Undies or anyone else who wants to jump in.
    I am in a similar situation with my 05 3700 amd finally looking to dump the rst fork for an affordable rigid fork. Do you recall what the axle to crown measurements of the dimensions fork and the stock rst fork were? Trek specs the 05 3700 at 412mm, I measured roughly 444mm!?
    Thanks to all that reply!

    Very cool.

    I noticed what looked like a brand new bike being thrown away by a neighbor, so I went over to look at the bike. Outside of some rusty bolts and a missing rear derailleur, it appeared to be in fantastic condition so I asked if I could take it. He agreed. I didn't know what I was getting into but later learned that it was just the hanger that had snapped.

    With my wife wanting to do some light trail riding, I figure that repairing this old Trek 3700 would be a fun project. It's even the same color as your. Anyway, just wanted to thank you for posting since this thread has inspired me to get cracking.
