Algupära
The Spire Disc is Radon's full-carbon road platform — brought in to answer riders who want a genuine carbon frame and fork without spending boutique money. Both frame and fork are carbon, with the frame hitting ~950 g at XS size and the fork at ~420 g. The 2025 top build was described by Radon as the lightest road bike they had built in series to date, with Newmen Streem Climbing wheels at 1,045 g. The Spire balances a sporty-endurance geometry — faster than pure comfort bikes, less punishing than race geometry.

Verdikt
+Tugevused
- Full carbon frame and fork at a direct-to-consumer price well below comparable retail carbon road bikes
- Available with top-tier groupsets: Ultegra Di2 and SRAM Force AXS
- Light Newmen Streem Climbing wheelset on 2025 10.0 is a genuine premium touch
−Nõrkused
- 30 mm max tire clearance limits use on rough surfaces vs more versatile all-road bikes
- Sporty geometry may not suit riders wanting pure endurance comfort
- Direct-only purchase requires accurate size selection without a test ride
