100% hand crafted in the United States!  The Micro Mini is our smallest frame and is designed to fit riders 4’2” and under.  The Micro Mini features a 7” seat tube with a 66-degree angle.  This keeps the seat low and behind the rider and out of the way when pedaling.

CRUPI Mini Frame

The Mini frame is designed to fit riders 4’3” to 4’5”.  The Mini features an 8” seat tube with a 66-degree angle.  This keeps the seat low and behind the rider and out of the way when pedaling.  The frame also features a slightly easier head angle than most frames at 72 degrees.  

CRUPI Junior Frame

The Junior frame is designed to fit riders 4’5” to 4’7” (ages 8 to 10).  Like our other smaller frames, the Junior features an 8” seat tube with a 66-degree angle.  This keeps the seat low and behind the rider and out of the way when pedaling.  The frame also features a slightly easier head angle than most frames at 72 degrees.

CRUPI Expert Frame

Our Expert frame is designed to fit riders 4’7” to 5’1” (ages 9 to 11).  Like our other smaller frames, the Junior features an 8” seat tube with a 66-degree angle.  This keeps the seat low and behind the rider and out of the way when pedaling.  The frame also features a slightly easier head angle than most frames at 72 degrees.

CRUPI Expert XL Frame

Our Expert XL frame is a great transitional frame designed to fit riders 5’1” to 5’5” (ages 11 to 13).  This is the smallest frame we make with an 1-1/8” head tube as riders getting to this size and weight are usually ready for a stronger fork and stem.  

CRUPI Expert XXL Frame  NEW

Our Expert XXL frame is a great transitional frame designed to fit riders 5’3” to 5’5” (ages 12 to 14).  Perfect for lighter riders or girls needing the extra length in the front but not ready to jump up to the heavier Pro frame. 

CRUPI Pro Frame

The smallest of our Pro model frames, this frame features more conventional geometry and bigger diameter top and down tubes.  When you are ready to move up from the Expert XL model, this frame is the most logical choice.  This frame is great transitional frame for a bigger 14 to 15 year old. 

CRUPI Pro XL Frame

CRUPI Pro XXL Frame

The Pro XXL frame features more conventional geometry and bigger diameter top and down tubes.  This frame is great for taller riders (6’ and up) who need a steeper head angle, a little more working space in the front end and a stiffer frame.

All new for 2011 with completely new geometry.  The youngest Cruiser class now offered is for 8 year olds and under (meaning you can race this class if you’re 8 or younger) and is one of the fastest growing classes today.  This means more track time which helps with the 20" class!  This frame is designed to fit riders 4’5” to 4’7”.

CRUPI Expert Cruiser Frame - NEW!

We've now added a true Expert Cruiser size frame as our previous model was more of an Expert XL Cruiser size.  This new frame is designed to fit riders 4’7” to 5’1”.  This frame keeps the 1” head tube to keep it light weight up front where the Expert XL cruiser goes to the 1-1/8" head tube.

Our Expert Cruiser frame is designed to fit riders 5’1” to 5’5”.  The frame has a 1-1/8” head tube but with the Crupi  “Chameleon” headset, you can use a 1” fork and stem to lighten the bike and make it fit even smaller riders.  

CRUPI Pro Cruiser Frame

CRUPI Pro XL Cruiser Frame

The Pro XL Cruiser frame features more conventional cruiser geometry and bigger diameter top and down tubes.  This frame is great for taller riders (6’ and up) who need a steeper head angle, a little more working space in the front end and a stiffer frame.
