Big feet small frame-Ulock where?

[7797]

Hi all,
Just picked up 2 Trek 7.3's about a week ago and I have been having a difficult time placing my lock. Originally I had it on the seatpost but I keep bumping it one way or another and its not fun stopping quickly in a busy intersection when I kick it into the street. The way the frame is designed I cannot mount the bracket many places (large oval tubes). Without a bookbag where do you mount yours?

Strap mine down around the rear rack.

There are alternates: Twofish Lockblocks U-lock Mount or The Cycle Block will move the u-lock to the handlebar and/or stem. Twofish also makes The MegaBlock that goes around fat tubes, so you can hang your u-lock securely just about anywhere.
