Redline offer three levels of race bike. The T/T series Cromo-framed bikes (T/T stands for Track and Trail) these are entry-level bikes for those who aren't too serious and don't want a race-only bike, they also don't come in the smaller sizes (apart from the 16"). Next up the Proline series; these have aluminium frames and are full-on race bikes, but they don't break the bank, in fact these have been our best-selling race bikes for the past few years. Above that is the Flight series - the extra money you spend on one of these is definitely worth it, they are lighter and much better specc'd and they use the same frame as the Redline team. The next thing to get your head around is sizing, all race bikes are sized by the names they use and although they do differ slightly, Redline recommendations here are useful:

Micro: 3’ 8” & under. Ages 5 and under approx.
Mini: 3' 7" to 4' 10". Ages 6-7 approx.
Junior: 4’5” to 4’ 8”. Ages 8-9 approx.
Expert: 4’6” to 5’3”. Ages 9-11 approx.
Expert XL: 5’ 8” to 5’ 5”. Ages 12-14 approx.
