PRONE– HARDTAIL TRAIL 29”
Tough hardtail, for your favourite trail shredding. Two models for slightly different applications. The 27.5” version is slacker, more aggressive and designed for forks with longer travel. The big wheel (29”) version with a bit steeper and „pedal friendly” angles and bigger frame sizing is a great choice for long, epic rides. Both frames have been built in line with our dirt jumping heritage – we used beefy AL6061 tubes with custom butting. The Prones are tough as nails and will survive a lot of abuse.
