The recently redesigned Hutchinson Python 3 Racing Lab, now in its third iteration, offers a balanced mix of speed, grip, and durability that qualifies it as a versatile all-round option. This performance tyre excels in drier, summer conditions, showing some limitations in muddy terrain.

Hutchinson Python 3 Racing Lab - Technical details
Originally released almost 30 years ago, the Python tread design achieved immediate success, earning Paola Pezzo a gold medal at the Atlanta Olympics, the first games to feature mountain biking. With the Olympics returning to Paris in 2024, it’s fitting to see an updated version of this iconic tyre.
While the new Python incorporates many advancements, its tread design remains recognisable, featuring the continuous zig-zag centre line, open centre pattern, and closely packed side edge knobs that hark back to the original.
Changes from the Python 2 version are minimal, with the updated Racing Lab version retaining the same carcass, featuring a three-layer 66 TPI casing, a full bead-to-bead Hardskin protection layer, and Race Ripost XC compound. The primary changes are in the tread shape, which now includes a wider centre tread design claimed to offer more traction under braking and acceleration, and wider spaced side edge knobs, while still maintaining an open design to help clear mud.
The Racing Lab version of the Python 3 on test is available in 29 x 2.3” and 2.4” widths, both offered in black or tan walls. The claimed weight for the 2.3” is 780g (+/- 7%), and despite this range effectively giving Hutchinson 56g of leeway on either side of the claimed weight, our pair were almost exact at 783g and 776g.
Fitting and inflating the tyres was straightforward. I was able to mount them securely onto a pair of Hunt XC Wide V3 wheels without any tools or tyre levers, and they inflated easily with a track pump. The tyres measured an actual width of 2.25 inches on the 28mm internal width front rim, and 2.2 inches on the 26mm internal width rear Hunt XC Wide MTB wheelset. This is slightly below the claimed size, but I would expect them to match the stated 2.3” size when fitted to rims of 30mm or wider.
Hutchinson Python 3 Racing Lab tyre – Performance
Very few tyres that boldly claim to be all-round performers can effectively deliver on that promise without some compromises. The Python is no exception, with its main shortcoming being traction in muddy conditions, both when braking and accelerating. I kept the tyre on through a wide range of weather conditions and used it on courses and in races with slippery sections, finding that this was an area where I lost ground against other riders. Despite running low pressures, down to 18 PSI on the rear, certain sections required careful weighting and balancing to maintain traction. The tread depth might have the biggest impact on mud traction, but the reasonably open pattern does at least help in clearing mud effectively.
On drier surfaces, including loose over hardpack, typical Welsh trail centres, and firm tracks, the tyre performs well. The open tread design is noticeable when cornering, which can be unnerving at first as you learn to trust the tyre’s ability to slide and then grip on the edge knobs. I found this most noticeable and easiest to adapt to through bermed corners.
The Python 3 feels swift but not rapid, rolling smoothly on all surfaces with very little noise or hum. While there is no data available on rolling resistance and Hutchinson makes no claims regarding speed or drag, it doesn’t seem likely to compete with the very fastest tyres available. However, it feels stronger and offers more grip than some race-focused options. For pure speed, Hutchinson offers the Python Race version.
The casing features a three-layer design, each with 66 TPI, which is lower than some race tyre options and influences the feel. While it can't match the thinnest, highest TPI designs, the layered construction features a puncture protection Hardskin layer in the middle, enhancing puncture resistance. I haven’t suffered any punctures while using these tyres, although it’s unclear whether this is due to the effectiveness of the Hardskin protection layer or simply good luck while riding.
Hutchinson Python 3 Racing Lab tyre –Verdict
The Python 3 Racing Lab costs £60 in all sizes and colours, which is comparable to rival options. Vittoria and Schwalbe are popular choices among riders and racers. The race-focused Mezcal XC Race we previously tested, or the similar design with a reinforced sidewall XC Trail option, now costs £60. A Schwalbe Rocket Ron Evo Super Race Addix Speed is more expensive at £67, while Continental prices the premium Cross King and Race King ProTection models at £68.
I have enjoyed riding the Hutchinson Python 3 Racing Lab in nearly all of our typical spring and summer trail conditions. Although there is no data to confirm either way, I found the performance and speed to be good, and I believe 95% of riders would probably agree. Unless you are chasing every second and are willing to invest in race-specific tyres, I think the Python 3 is excellent for general trail riding while still being capable enough for races.
