  The Catalina 2.0 Junior Race Frame is all new for 2025. Although it still has our race winning geometry, the frame now features wrap around seat stays, a slightly shorter seat tube & our all new built-in Disc Adapter. Axle mounted adapters are no longer needed!   Our All-American Made frame w/ a 18.5" top tube is designed for riders 4"-5" to 4'-7".  Catalina 2.0 Race Frames feature 1" Integrated head tubes & use a traditional EB24 Euro BB. Built w/ seamless drawn 6061 T6 Butted tubing Tubing is squared off at the ends to provide more welding surface Larger diameter square shaped down tubes stiffen & strengthen Chain stay tubes are tear drop shaped for a very strong & stiff back end 3/8" (or 10mm) axle slots are parallel to the ground meaning no matter what position your rear wheel is in; the frame geometry will not change Thicker 3D drop-outs for extra stiffness when using a Disc Brake which still allow the use of regular chain tensioners for ease of rear wheel ins
