FAQ
How Does the Collous T compare to the Siskiu T and Collosus N
It bridges the two worlds - lighter and snappier than the COLLOSUS N, but more capable and confident on descents than the SISKIU T.
What's the difference between Faux Bar, IFS Compact and Original IFS suspension designs?
The Faux Bar is simple, efficient, and built for speed — a reliable setup that gets the job done. The IFS (Independent Floating Suspension) takes things up a notch, built for bigger travel with improved traction and smoother control across rough terrain. The IFS Compact keeps that same responsive feel in a lighter, more streamlined design, perfect for smaller-travel bikes.
Can I upgrade to to a shorter or Longer Fork?
Yes you can go up to plus or minus 10mm in fork travel. +10mm to 170mm if you want a slacker more mini-enduro style setup or down to 150mm if you'd like a slightly steeper more trail orientated setup.
What wheel size does the bike use?
It comes standard with 29” wheels front and rear for speed and stability, but depending on model and preference, a mullet setup is possible for a more playful ride - thanks to the flip chip. Just add a 27.5" rear wheel and tyre.
Can I run a dual crown fork?
No, you cannot use a dual crown fork as the frame is not designed or tested to withstand the different loads.
Can I run a coil shock?
Absolutely! The frame is designed to handle both coil and air shocks, so you can tune your setup to match your riding style and terrain. Just keep in mind that compatibility may vary depending on the coil shock you choose.
What is the maximum tyre size the frame will fit?
29 x 2.60"
Is the Frame UDH compatible?
Yes, the COLLOSUS T uses a UDH derailleur hanger, making spare dropouts easy to find and making the frame fully compatible with Sram full mount derailleurs
