SRsix – Shimano 105 12 Spd

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. Most of the story comes from all-round road tires that balance speed and comfort, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding. This means it's neither sluggish nor razor-fast - more of a versatile middle ground.

How it climbs: 2.8/10. Within Road bikes, it lands below average. On climbs, the lowest gear feels moderate. The easiest gear works out to about 28.6 gear inches. On the ‘easier low gear’ scale, it sits around ~47% versus similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

For a triathlon build, given a fairly neutral posture, scoring 10.0/10 on aero, it’s a speed-first, wind-focused setup where aerodynamics is the main lever. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. Tyres around 28mm fit a faster road setup and usually keep drag in check. A tidier cockpit and cable routing can help a little once you’re riding quickly. Not every brand publishes the same detail, so this leans on the clearest available specs. If you ride at higher speeds, this is the kind of bike that’s designed to pay you back for that effort.

Balanced fit - a middle ground between comfort and speed. That's driven by the bar sits about 100 mm below the saddle (a large drop), and you'll be stretched forward about 569 mm in total (long). You'll likely be near 39 degrees of lean.

Net result: Limited Adjustment. Main reasons for the fit flexibility result: With a one-piece cockpit, the bike is more fixed in its stock position. Plus, Headset-style internal routing makes front-end changes more time-consuming.

This scores 3.2/10 for comfort, so it feels firm out on the road. That’s the reason it lands as Firm. It’s running about 28 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is neutral (posture 6/10, torso ~39°), which balances comfort and responsiveness pretty well.

This looks like strong value without any tricky caveats. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it comes in about 17% under the typical level for similar builds. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 86% of listings. Quick reference: €4.395 listed versus about €5.268 for a comparable build. Put simply: this is strong value for what’s included.

This bike is built for smooth pavement and fast road riding. The tire size is around 28 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
