CannondaleF-Si
Algupära
F-Si oli Cannondale'i lipulaev XC hardtail, mis loodi Bedfordis, Pennsylvanias Flash F29 järeltulijana ja toodi turule mudeliaastal 2015, et püüelda World Cup XC poodiumikohtade poole. Selle tunnuslik trikk oli patenteeritud Lefty Ocho ühe jalaga kahvel koos asümmeetrilise Si tagumise kolmnurga ja Ai nihutatud rummu vahega, mis võimaldas inseneridel kasutada väga lühikesi 429 mm ketti ilma rehvi kliirensi või ratta nihketa. Raam kasutas Cannondale'i BallisTec süsinikukihti, kusjuures Hi-MOD versioon kaalus alla 900 g. Aastatel 2016–2022 oli see platvorm, millel Manuel Fumic, Henrique Avancini ja Anton Cooper võistlesid. 2024. aastaks langes nõudlus puhta hardtaili järele, kuna kerge Scalpel täisvedrustus võttis XC ülesanded üle, ja F-Si kadus vaikselt Cannondale'i ülemaailmsest valikust, kusjuures viimased 2024. aasta Carbon 4 ehitused olid edasimüüjate juures väljamüügil olevad varud.
Tehnilised andmed
- Raam
- BallisTec Carbon (Hi-MOD on top builds) with SAVE Micro-Suspension flex zones, PF30-83 BB, tapered head tube, Speed Release 12mm thru-axle and Ai Offset rear end. Hi-MOD frame ~900g — the lightest MTB frame Cannondale has built.
- Kahvel
- Cannondale Lefty Ocho single-leg fork, 100mm travel, 55mm offset (29"). Carbon version ~1515g, alloy ~1735g; needle-bearing internals for low-friction stroke.
- Jõuülekanne
- 1x12 across the range: Shimano XT/SLX (10-51) with HollowGram 34T crank on mid builds; SRAM X01/XX1 Eagle on premium; World Cup ran full SRAM XX1 Eagle.
- Pidurid
- Hydraulic disc, model varies by trim: Shimano Deore 160/160mm (Carbon 3), Shimano XT (Carbon 2), SRAM Level T (lower) up to SRAM Level Ultimate (World Cup).
- Rattad
- 29" tubeless-ready. Mid builds: Stan's NoTubes Crest MK3 rims, Lefty 60 front hub + Shimano/HollowGram rear (12x148mm Boost with 6mm Ai offset). Carbon 2: HollowGram 23 carbon; World Cup: ENVE M525 carbon w/ DT Swiss hubs.
- Rehvid
- Schwalbe Racing Ray (front) / Racing Ralph (rear), 29x2.25", tubeless ready; some builds spec'd narrower 2.1" Racing Ralph.
- Vedrustus
- Hardtail — front only, 100mm via Lefty Ocho. Rear compliance from SAVE Micro-Suspension flex zones in the carbon stays.
- Rooliplokk
- Cannondale 2 flat alloy bar (760mm), Cannondale alloy 7° stem, Cannondale 2 carbon seatpost (27.2x400mm) on mid builds.
- Sadul
- Fabric Scoop Shallow (Elite on mid builds) on a Cannondale 27.2mm carbon/alloy seatpost.
- Geomeetria
- Race XC hardtail: 69° head angle, 55mm fork offset, short ~427-429mm chainstays (enabled by Ai offset), 100mm front travel. Fast-but-tameable handling — stable yet playful.
- Kaal
- ~8.4 kg (World Cup, claimed) to ~9.6 kg (Carbon 2). Frame Hi-MOD ~900g, Lefty Ocho carbon ~1515g.
Verdikt
- Exceptionally light and stiff — the ~900g Hi-MOD frame plus low-friction Lefty Ocho deliver rapid acceleration and a vivid sense of speed on climbs
- Short Ai-offset chainstays with neutral rear-wheel dish keep climbing traction and put down power efficiently
- Best-in-class ride quality for a hardtail: SAVE micro-suspension flex zones take the edge off rough trail
- Lefty Ocho offers serious fore/aft stiffness and excellent small-bump sensitivity in its 100mm travel
- Modern, more confident XC geometry (69° head angle) makes it stable yet playful, not twitchy
- Stock 2.1-2.25" tyres are too narrow for many trails — riders quickly want wider rubber
- Heavy reliance on proprietary parts (Lefty hub/fork, Ai offset, HollowGram) — you can't swap in standard wheels or a normal fork
- Lefty service and spare availability is harder/pricier than a conventional fork; intimidates buyers and dealers
- Reported cockpit ergonomics niggle: some brake/shifter combos sat awkwardly for the thumb
- Pure hardtail focus narrows appeal as lightweight full-suspension XC bikes (Scalpel) close the weight gap
