Once the dry setup was sorted, the next problem was rain. XCO races run in any weather. If I can swap tires for wet conditions, I want to. But what exactly do I need? I started by taking stock of what we already have.
What We Already Own
Front candidates:
- Barzo XC Race 2.4 (current race front)
- Barzo XC Race 2.35 (last year’s front, sitting on a spare wheelset)
Rear candidates:
- Barzo XC Race 2.25 (purchased last year, unused)
The question: can this inventory handle wet conditions? And does adding one Torrente change things enough to justify the cost?
Barzo vs. Torrente — What’s Actually Different
Within Vittoria’s XCO lineup, Barzo and Torrente have distinctly different personalities.
The Barzo has a relatively connected center knob pattern — good balance of rolling efficiency and light mud performance. It handles semi-wet and light mud well. The downside: the center knobs can pack with mud in deeper conditions.
The Torrente has taller knobs with wider spacing. Mud clearance is clearly superior. In actual mud, it outperforms the Barzo meaningfully.
| Barzo | Torrente | |
|---|---|---|
| Semi-wet | ◎ | △ (heavy rolling) |
| Light mud | ○ | ○ |
| Real mud | △ (packs up) | ◎ |
Think of it this way: Barzo owns semi-wet. Torrente owns mud.
“What About Just Trimming the Barzo Knobs?”
The idea of modifying an existing Barzo as a wet tire came up. Short answer: no.
The Barzo’s limitation in mud isn’t knob height — it’s knob spacing. Removing knobs aggressively introduces unpredictable performance changes, durability concerns, and handling risks. The time and risk involved aren’t worth it when a Torrente exists.
Does the Rear Actually Need a Torrente?
This is where I spent the most time.
Conventional wisdom says front and rear Torrente is the optimal mud setup. In practice though, the picture is more nuanced.
Here’s the conclusion I arrived at: if the course is so muddy that a rear Torrente is genuinely necessary to climb, you’re probably walking or running that section anyway — and the time difference is minimal.
Meanwhile, a rear Torrente carries real costs:
- Heavy rolling on paved sections
- Slow on semi-dry terrain
- Dulled acceleration
XCO courses aren’t all mud. Both Hakusan and Azumino mix paved climbs and hardpack sections with the technical parts. Running a Torrente at the rear means accumulating losses across those sections.
Front First
Front and rear have different jobs:
- Front: steer, brake, don’t crash
- Rear: drive, climb, accelerate
In muddy conditions, the front is the first thing to fail. The steering goes. The brakes go. The crashes start. That’s what ends races.
So priority goes to the front. Torrente front / Barzo rear keeps the most important grip where it matters while preserving roll speed at the rear. Likely more rational than front and rear Torrente for mixed-condition XCO.
Setups by Condition
| Condition | Front | Rear |
|---|---|---|
| Dry | Barzo 2.4 | Mezcal 2.4 |
| Semi-wet / half-wet | Barzo 2.4 | Barzo 2.25 |
| Heavy wet / real mud | Torrente 2.25 | Barzo 2.25 |
| Deep mud (rare) | Torrente | Torrente |
The Barzo 2.25 rear already handles semi-wet. It’s already in the bag. The gap is heavy wet and above — that’s where a front Torrente comes in.
The Decision
Two options: buy one Torrente 2.25 as a front-only wet option, or don’t buy it and accept the limitation.
No purchase: Current inventory handles dry through semi-wet without issue. In genuine mud, accept the result. There’s a decent chance a mud race doesn’t happen.
Buy one Torrente 2.25: Keep it specifically as a front swap for heavy wet or mud. The reason for 2.25 rather than 2.4: experienced riders say narrower tires cut into mud better, and a narrower tire carries less mud with it through each rotation.
The honest reality: Azumino Nationals is shaping up to be a natural endpoint for this season. My son’s last race as a junior. Cost control matters.
So the actual decision: buy the Torrente only if the forecast demands it.
If there’s no rain in the forecast one week out, don’t buy it. If rain or unstable weather is showing, buy one. It’s rainy season — hard to read until close to the date. But waiting until the last moment also means no wasted spend.
One action item: confirm which local shops stock it and check online availability in advance. That’s enough preparation.
Side Note — Why Vittoria? Why Tan Walls?
After all that analysis, the honest reason we run Vittoria is simple.
They look good.
The brand, the logo, the name, the tan sidewall color against the frame — it just has a look. The aesthetic works. I wrote a lot about performance characteristics, but that’s where it ends up.
Whether a rider likes the look of their own bike matters. Especially for a teenage kid. Going into a race feeling good about your setup is worth something that doesn’t show up in the data.
