I am Tim O'Donnell and welcome to the Shamrock Cycles website.  Shamrock Cycles is a custom frame building shop dedicated to providing hands on service and delivering the best possible product to my customers.   I provide custom road, track, mountain and cross frames as well as complete bike builds at affordable prices. 

Please take your time and look around the site.  My hope is that you will find the general information about Shamrock Cycles and it will prompt you to call me immediately with credit card in hand!  But, feel free to call or email with any questions or comments you may have and you can keep the card in your pocket.
