BianchiInfinito CV
Algupära
Infinito CV turule toodi 2013. aastal kui maailma esimene seeriatootmises olev jalgratas, mis kasutas Countervaili – viskoelastset süsinikkomposiiti, mille töötas algselt välja USA kosmosetööstuse ettevõte Materials Sciences Corporation NASA satelliidikomponentide ja sõjaliste rakenduste jaoks. Bianchi litsentsis tehnoloogia eranditult jalgrattasõiduks ja integreeris selle Infinito süsinikukihti, et neutraliseerida umbes 80% teevibratsioonist, suurendades samal ajal väändejäikust. Tulemuseks oli Kevadklassika relv, mis tõestas end selliste sõitjate nagu Vincenzo Nibali ja LottoNL-Jumbo meeskonna käes Pariis-Roubaix' ja Flandria tuuril. Vastupidavusele suunatud geomeetriaga – kõrgem roolikinnitus, pikemad tagumised ketihoovad, 32 mm rehvide kliirens – jääb Infinito CV Bianchi määravaks pikamaa võistlusrattaks ja Countervaili tehnoloogia ajalooliseks koduks.
Tehnilised andmed
- Raam
- Full carbon monocoque with Countervail viscoelastic carbon layup; PF86 BB, 12x142mm thru-axle (disc), ~950g frame (size 55); downtube +5mm on 57-61cm sizes for torsional stiffness
- Kahvel
- Bianchi full carbon with Countervail, 1.5" tapered steerer, flat-mount, 12x100mm thru-axle (~390g); rigid road fork
- Jõuülekanne
- Multiple builds: Shimano 105 / Ultegra (Di2) / Dura-Ace Di2 R9170 and Campagnolo up to Super Record; 2x11-speed
- Pidurid
- Disc model: flat-mount hydraulic disc (Shimano), 140/160mm rotors. Rim model: dual-pivot caliper rim brakes
- Rattad
- Build-dependent: e.g. Fulcrum Racing 418 Disc or Vision Metron 40; 700c, 12x100/142mm thru-axle (disc)
- Rehvid
- 700c, typically 25-28mm stock (Vittoria Rubino Pro 700x28C); disc frame clears up to 32mm, rim-brake version limited to 28mm
- Vedrustus
- Rigid (no suspension); compliance comes from Countervail vibration-cancelling carbon (~80% road vibration absorbed)
- Rooliplokk
- Alloy or carbon road handlebar/stem depending on build (e.g. FSA Wing bar); internal/semi-integrated cable routing on disc model
- Sadul
- Build-dependent road saddle (commonly Fizik); standard 27.2mm seatpost
- Geomeetria
- Endurance race geometry: taller head tube (~20mm taller than Oltre), longer chainstays for stability; size 57 ~73.5° head / 72.5° seat angle, ~1004mm wheelbase
- Kaal
- ~7.5 kg (size 57, Dura-Ace Di2 build); ~8.0 kg (size 59, Ultegra Di2 build)
Verdikt
- Countervail carbon cancels ~80% of road vibration — exceptional long-distance comfort without a compliance penalty in stiffness
- Superb blend of race-bike handling and endurance comfort; planted, stable feel
- Excellent straight-line stability and composure in crosswinds
- Disc version clears up to 32mm tires, allowing comfort/grip upgrades
- Iconic Bianchi celeste heritage with proven WorldTour pedigree (Nibali, LottoNL-Jumbo)
- Limited sprinting acceleration / explosive punch versus dedicated race bikes
- Loses a touch of precision at the cornering limit; can understeer with an aggressive position
- Cable routing around the cockpit can look messy on some builds
- Expensive — mid-tier finishing kit on builds that cost flagship money
- Rim-brake version capped at 28mm tires, limiting comfort gains versus disc model
