Planet X Tempest SRAM Red AXS XPLR

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. Versus the most speed-focused options, this build is shaped by very wide tires that create extra drag and a high-end drivetrain that tends to feel crisp under load. In real riding, it tends to feel slower when you try to hold a high tempo.

On steep roads, it comes in at 6.5/10. Within Road bikes, it lands above average. It’s set up for steady spinning on climbs. Your easiest gear lands around 18.4 gear inches. For the low gear, it’s right at the easy end — easier than about ~98% of similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. Good for keeping cadence steady on climbs without overcooking it. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

In gravel terms, that 4.5/10 aero rating suggests that it’s an all-round aero level without demanding big compromises elsewhere. What that means on the road is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The gravel tag is a useful clue for how wind efficiency ranks among the priorities. It’s a middle-ground feel: not the fastest possible in the wind, but not holding you back either.

Balanced fit - a middle ground between comfort and speed. Because bars are around 103 mm lower than the saddle, which is a large drop, and the forward stretch measures around 559 mm (long). Plan for roughly 40 degrees of lean.

Net result: Adjustable. This rating is mainly driven by the parts that affect adjustability: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts. Plus, Cable routing is on the simpler side, which helps adjustability. In practice, it is about how easy fit changes are with normal parts and service work.

Comfort comes out to 6.5/10, which usually translates to a nicely smooth ride. So it’s tagged Balanced overall. It’s running about 45 mm tires on 700c wheels, and extra tire volume helps mute vibration and small bumps on rough lanes and gravel patches. The posture is race-leaning (posture 7/10, torso ~40°), which puts more weight forward, so you notice more feedback through the hands and saddle.

This feels like you’re paying extra for the same kind of bike. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it’s about 20% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 46% of listings). Quick reference: €5.724 listed versus about €4.752 for a comparable build. Overall, it doesn’t look like the best value for the spec.

This bike is comfortable on gravel roads and unpaved back roads, and it still rides well on tarmac. Tires around 45 mm are well suited for gravel roads and unpaved connectors. The wheel setup (700c) supports that direction.
