Lub Cervelo R2 yuav tsum yog lub tsheb kauj vab sib tw tab sis peb pom cov duab geometry thiab caij ntawm 105 tus qauv tsim qauv qw nrov tsheb kauj vab
Cervélo muaj ob txoj kev tsheb kauj vab, R Series thiab S Series. Lub S Series yog aero muab, thaum R Series muaj ntau classic kev sib tw tsheb kauj vab. Lub R2 kuaj ntawm no yog lub cim tshiab ntawm lub tsheb kauj vab uas Stuart O'Grady caij mus rau kev ua tiav hauv Paris-Roubaix rov qab rau xyoo 2007, thiab coj lub teeb yuag no mus rau qhov tsis pom tus nqi yav dhau los, qis dua £ 2k. Lub plawv ntawm lub tsheb kauj vab no yog lub teeb thav duab tab sis nrog Shimano qhov zoo tshaj plaws thiab pheej yig 105 pawg, nws yuav tsum tuaj yeem ci.
The frame
Lub asymmetric BBright hauv qab bracket tso cai rau sab laug tes tuav los tsim kom muaj zog ntxiv.
R Series thav duab yog tsim los ua lub teeb, thiab Cervélo thov tias 56cm R2 ncej hnyav dua 1kg. Cov khoom zoo siab, tab sis tom qab ntawd yog qee yam ntawm lwm yam thev naus laus zis Cervélo tau pov rau ntawm lub tsheb kauj vab no. Nws yeej siv tib lub thav duab uas kim dua R3, uas nws tus kheej yog 24% stiffer ntawm lub taub hau raj dua li yav dhau los tiam R3 (nws tam sim no muaj ib tug tapered 1.375 mus rau 1.125in steerer) - nws siv squared-tawm oval hlab (Cervélo hu lawv 'Squoval') kom ua tau ib theem ntawm aerodynamics tsis hnov txog ntawm cov tsheb kauj vab hnyav tshaj plaws. Cervélo reckons cov hlab no txuag 7w piv rau yav dhau los R3, ntau dua tawm tsam lwm lub tsheb kauj vab. Nws yog qhov tseeb ntawm kev tshuaj xyuas thawj zaug tsuas yog xav txog ntau npaum li cas tau mus rau hauv tus ncej, zoo li lub rooj zaum squared-tawm, lub rooj zaum ultra-thin nyob qis qis lossis asymmetric BBright hauv qab bracket, uas tso cai rau sab laug tes chainstay los tsim kom muaj zog ntxiv.

Cervélo tham ntau txog pawg thiab ncav cuag kev ntsuas hauv nws cov ntaub ntawv, uas txhais tau hais tias cov tsheb kauj vab loj dua thiab siab dua nrog txhua qhov dhia dhia - qee yam uas tsis yog ib txwm muaj nrog lwm hom. Qhov ntawd yog qhov zoo, tshwj xeeb tshaj yog rau cov neeg caij tsheb me me, tab sis nws tsim qee qhov tsis zoo - piv txwv li, peb lub 54cm tester tiag tiag muaj lub hauv ntej-centre luv (ntsuas los ntawm BB mus rau nruab nrab ntawm lub hub pem hauv ntej) dua li 51cm tsheb kauj vab, ua tsaug rau lub taub hau lub kaum ntse ntse thiab ib rab diav nrog 10mm tsawg offset. Qhov ntawd ua rau lub log tsheb nruj tab sis txhais tau hais tias peb raug mob ntiv taw sib tshooj, uas yog qhov teeb meem rau peb ntawm qhov ceev ceev thiab teeb pom kev zoo (tsis yog lub tsheb kauj vab no yog tsim los rau, tab sis qhov twg ntau ntawm peb siv sijhawm ntau).
