Ride Impressions (Core Section)
Comfort: Long-Distance Focused Carbon Feel
The SLX delivers the smooth, refined ride you expect from a high-quality carbon endurance frame.
Comfort comes from compliance-tuned carbon construction and flex stays and full carbon fork to reduce vibration. This gives it room for wider tyres to absorb rough roads.
This combination reduces rider fatigue and helps keep you comfortable over long distances or imperfect road surfaces.
The ride isn’t soft, it’s controlled and damped, exactly what endurance riders want.
Handling: Stable but Engaging
The geometry is clearly endurance-biased, but not dull.
You get balanced cornering stability, predictable steering, confidence at higher speeds and calm behaviour in crosswinds.
The SLX feels composed rather than nervous, ideal for long descents or mixed-quality roads.
Stiffness & Acceleration: Performance Where It Counts
Despite its comfort focus, the Attain C:62 SLX is lively when you push.
The carbon frame and thru-axle design provide efficient power transfer, helping the bike accelerate smoothly and maintain momentum.
Electronic Shimano 105 Di2 shifting also helps maintain rhythm, gear changes are instant and precise, even under load.
This makes the bike feel responsive without harshness.

– Lightweight carbon construction
