Canyon just debuted their sick new Park Bro bike, and like every Park Bro bike before, it features a 425mm chainstay length on all the sizes. Checking around the industry, this has become the standard freeride Bro Brah size since the original Demo 9. The Kona Process 167? 425 chainstay. Rocky Slayer? 425 chainstay. Commencal Supreme SX? 425 chainstay. Literally every pedal bike from Transition, the ultimate Park Bro brand has 425 chainstays.
In the Canyon Torque lineup, from the smallest bike to the largest front center grows 96 mm, or 9.6 cm, or 3.8 in, or 0.11 yds, or 0.00006313 miles, or 14%.
For those same bikes, rear center grows 0 mm.
And the front center is at no risk of being called “short.”
I’ll extend an olive branch here, and concede that 425mm chainstays can be fun in certain circumstances, like if you’re building a dirt jump bike, or you’re 5’4″, or you suck at riding, or some combination of the three. But if you’re riding somewhere above walking pace, and are at or above global average height, and we’re talking about a full suspension for trail riding, 425 chainstays suck.
For the most part, bikes suck less than they used to. Suspension, tires, brakes, and (for the most part) geometry have all converged around some quality numbers that make sense for most riders. Chainstay length, however, is still determined with a dart board, or by monkeys with typewriters.
Your front center/rear center ratio determines your weight balance on the bike. Changing one number directly affects how the other number feels when you’re on the bike. You should probably change both numbers at the same time. This could be the next REVOLUTION!!! in geometry:
