Hello,
Hoping someone out there has a Bontrager DuoTrap Ant+ digital speed sensor for a Trek Madone.
Perhaps you have one from your old Madone? Perhaps you have it installed but prefer a gaping hole in the chainstay for water and mud evacuation?

Please contact me off list and name your price. Preferably less than retail unless it's tricked out to make me think I'm going faster.
