Tarmac SL7 Comp – Shimano 105 Di2

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. That's why it sits toward the faster end for comparable bikes. What pushes it in this direction is a light setup, an aero-leaning setup that reduces drag at higher speeds, narrow road tires that keep resistance low, and a solid drivetrain that supports efficient riding.

If your rides include hills, it rates 6.6/10 for climbing. Within Road bikes, it ranks above average. For hill work, the easiest gear is moderate. That lowest gear comes out around 28.6 gear inches. Compared with similar bikes, this low gear is easier than about ~47% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. At about 8.1 kg, it’s in a normal range, so gearing matters more than weight swings here. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

Category-wise (race-focused), aero-wise, at 7.8/10, it’s designed to feel efficient at higher speeds particularly on flatter, wind-exposed sections. Put simply, it’s built with speed in mind, with choices that reduce wind drag once you’re riding faster. Its race label helps explain the balance between speed, comfort, and versatility. This tyre size generally plays nicely with aero goals compared with very wide all-road tyres. A more integrated front end usually reduces minor drag points around the cockpit. In real riding, it tends to reward holding speed: the faster you go, the more the aero design helps.

Sporty fit - you'll lean forward more and feel ready to push the pace. It feels this way because there's about 104 mm of drop to the bars (large), with roughly 566 mm of forward stretch to the bar (long). You'll likely be near 39 degrees of lean.

In Road / Race, Why this fit flexibility rating: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Cable routing is on the simpler side, which helps adjustability; The listed seatpost details do not show clear restrictions or extra flexibility signals. So it lands in Moderately Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Ride comfort is 2.4/10 — on a real ride it feels harsh on rough surfaces. So it’s tagged Race-Stiff overall. It’s running about 26 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is race-leaning (posture 7/10, torso ~39°), which tends to feel more direct, especially over rougher sections.

This looks like a great buy for the spec on paper. 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 parts list, it’s roughly 30% cheaper than what similar builds typically cost. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 89% of listings. Quick reference: €3.348 listed versus about €4.752 for a comparable build. Put simply: this is strong value for what’s included.

This bike is best when your rides stay on clean tarmac. The tire size is around 26 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
