Maxxis Aspen 2.4 MaxxSpeed

Fast dry to slightly mixed course XC tire. Lightweight and race-proven.

Why I like it

The Aspen 2.4 MaxxSpeed is my go-to for dry and mixed-condition XC races. It’s crazy fast-rolling and still grips when you need it. I typically run it up front or as a front/rear combo, and it shines when speed is everything.

Quick Specs

120 TPI casing

MaxxSpeed compound
Great volume for comfort + grip
Fast rolling

In My Setup

I run the 120 TPI version — solid puncture resistance and still very fast.
On smoother courses, I run around 12 psi front / 13 psi rear, and up to 16f/18r for rockier terrain — always with Vittoria Airliners for insert support.
These numbers are tuned to my weight and riding style — your pressures will differ. I recommend using the SILCA Pro Tire Pressure Calculator to dial yours in.

Who It’s For

XC racers who want a lightweight tire that doesn’t compromise too much on grip. If your course is dry, fast, and not too chunky — this is probably your best bet.

Notes

MaxxSpeed compound claims 25% lower rolling resistance — I can’t verify the number but it feels quick and grippy.
I always ride with Vittoria Airliner inserts — they let me push tire pressure lower without risking burps or rim strikes.
