BianchiOltre RC
Algupära
Oltre RC on Bianchi hüperjalgrataste lipulaev, mis lasti turule 2022. aastal legendaarse Oltre XR4 järeltulijana, millega sõitjad nagu Primoz Roglic ja Jakob Fuglsang võitsid Grand Tour'i ja klassikuid. Bianchi Reparto Corse võistlusosakond Treviglios, Itaalias, loobus XR4 Countervail-konstruktsioonist puhta aerodünaamilise kasu nimel – kõige silmatorkavamalt patenteeritavatest Air Deflectoritest, F1-st inspireeritud tiibadest, mis kasvavad välja peatorust ja suunavad madala rõhuga keeriseid ümber sõitja. Bianchi väidab, et see säästab 17 vatti kiirusel 50 km/h võrreldes XR4-ga ja 45 sekundit 40 km distantsil võimsusel 250 W. Praegu sõidetakse UCI WorldTour'il Team Arkea-B&B Hotelsi poolt ning Oltre RC on kõige kallim ja kompromissitum Celeste-värvi võistlusjalgratas, mille Bianchi on kunagi ehitanud.
Tehnilised andmed
- Raam
- Carbon, aero monocoque with patent-pending Air Deflectors; electronic-drivetrain-only, PressFit BB86.5x41mm, integrated seat clamp, thru-axle 12x142mm. Frame 915g (size 55)
- Kahvel
- Bianchi Oltre RC full-carbon aero fork, integrated 1 1/4" steerer, flat-mount caliper, thru-axle 12x100mm, 420g
- Jõuülekanne
- Electronic only — SRAM Red eTap AXS / Shimano Dura-Ace R9270 Di2 / Campagnolo Super Record EPS (12-speed)
- Pidurid
- Hydraulic disc, flat-mount calipers (groupset-matched: SRAM/Shimano/Campagnolo)
- Rattad
- Reparto Corse carbon, tubeless-ready, 21mm internal width, SKF ceramic bearings — front RC50 SPB Tech (50mm), rear RC65 SPBTech (65mm); ~1,540g/set claimed
- Rehvid
- Pirelli P-Zero Race SL TLR 700x28c (clearance up to 30mm)
- Vedrustus
- Rigid (no suspension); RC frame omits the Pro's Countervail vibration-damping for maximum stiffness
- Rooliplokk
- Reparto Corse aero one-piece carbon cockpit with split/vented stem and central air channel; fully integrated cable routing
- Sadul
- Reparto Corse RC139 Carbon Air — 3D-printed variable-density padding, ~168g
- Geomeetria
- Aggressive race geometry. Size 55: head angle 72.5°, effective seat angle 73.5°, top tube 550mm, stack 543mm, reach 393mm
- Kaal
- 6.85 kg / 15.1 lb claimed (size 55, complete bike)
Verdikt
- Class-leading aerodynamics — patent-pending Air Deflectors and vented cockpit, claimed 17W saved at 50 km/h vs the Oltre XR4 (~45s over 40km at 250W)
- Exceptional high-speed stability — composed and planted even north of 70 km/h, inspiring cornering confidence
- Outstanding power transfer — chunky chainstays and stiff bottom bracket put every watt into forward drive, seated or sprinting
- Race-bred handling — testers carried more corner speed than on rival aero bikes
- RC139 Carbon Air saddle (~168g, 3D-printed) keeps an aggressive position comfortable for hours
- Punishingly stiff ride — no Countervail (unlike the Oltre Pro), so road buzz and bumps reach the rider directly
- Heavy for the category — 6.85 kg makes it a liability on steep climbs vs lightweight all-rounders
- Extreme price — around €15,149 for the SRAM Red AXS build causes sticker shock
- Polarising aesthetics — aggressive, asymmetric tube shaping divides opinion
- No mechanical-drivetrain or rim-brake option; electronic-only frame limits flexibility
