Scott Speedster ntau yam tau nyob ib puag ncig tau ntau xyoo, thiab txawm hais tias nws tsis sawv cev rau kev txiav ntug ntawm kev siv tsheb kauj vab, nws tau hloov zuj zus los ntawm lub sijhawm. Lub Speedster 50 nta lub tuam txhab hu ua 'puab optimized ob-butted alloy tubing thiab ib haiv neeg proven geometry uas muab ib tug aerodynamic kom zoo dua thiab zoo heev ua tau zoo'. Qhov tseem ceeb, qhov no txhais tau tias nws tau ntim qee cov khoom siv high-end ntawm tus nqi txaus nyiam heev. Tab sis nws puas tau tsom mus rau kev ua tau zoo los muab kev nplij siab mus ntev? Cia peb kawm…
Frameset
Scott txoj kev pheej yig rau kev caij tsheb ua haujlwm zoo li aero-profiled alloy tubing, uas muab cov lus pom zoo rau nws lub hom phiaj. Scott hais tias nws muaj 20% nce hauv aerodynamic kev ua tau zoo tshaj lub tsheb kauj vab nrog lub voj voog puag ncig, thiab qhov nruab nrab 5% tsawg zog los txhawb nqa qhov nrawm. Kom meej meej, tsis muaj cua ntsawj ntshab thiab ib txhais tes ntawm cov tsho dawb, peb tsis tuaj yeem lees paub lossis tsis lees paub qhov no, tab sis cov nuj nqis yeej zoo siab. Cov roj, hauv qab raj yog qhov zoo tshaj plaws, thaum txoj hlua sab saum toj kuj txo qhov luaj li cas ntawm daim duab peb sab tom qab, nrog rau lub hom phiaj ntawm kev qhia qee qhov kev ua raws txoj kab ntsug ntawm lub nraub qaum kawg kom sib npaug ntawm qhov sib npaug ntawm sab xub ntiag. Geometry-wise, Scott ua raws cov kab tib yam li Mekk, tab sis nrog lub taub hau me ntsis steeper muab qhov muaj peev xwm txawm tias muaj zog dua. Nws lub logbase, ntawm qhov ntsuas 971mm, muab tso rau hauv thaj tsam ntawm kev sib tw tsheb kauj vab.
Groupset
Claris cov cuab yeej siv thoob plaws hauv kev tsim, los ntawm 50/39/30 chainset mus rau yim-ceev shifters thiab pem hauv ntej derailleur (lub rear mech yog upgraded rau Sora). Triple chainset muab kev xaiv yuav luag befuddling ntawm 24 lub zog, sib tw rau 11-30 cassette (ib 50/34 chainset version ntawm lub tsheb kauj vab no kuj muaj). Muaj kev ncaj ncees leap ntawm cov piv txwv no, ua kom raug xaiv iav qhov tsim nyog. Tektro R312 dual-pivot brakes yog qhov nyuaj rau kev hloov kho dua li Shimano cov khoom siv nkag, ib nrab vim tsis muaj kev txawj ntse rau Claris qib qhov kev ua.
khoom siv tiav
Lub tsheb kauj vab yog peppered nrog alloy qhov chaw los ntawm Scott tus kheej Syncros band. Cov handlebars compact yog qhov tsim nyog - peb pom peb txhais tes tso rau saum lub hau tsis tu ncua kom coj mus rhaub cov mais (tab sis qhov no yuav yog kom tsis txhob tuav cov Claris nres hoods). Lub FL2.5 lub eeb yog qhov sib sib zog nqus tab sis ruaj khov, yog li koj tsis xav tias koj tab tom dhia ncig.
Wheels
Raws li lwm lub tsheb kauj vab tau sim ntawm no, Scott lub wheelset yog tsim los kom ruaj khov thiab ua haujlwm zoo. Lub Syncros Aero 27s yog qhov kev cia siab rau txhua lub xyoo kev cob qhia log, tab sis lawv yuav yog thawj qhov chaw zoo pib nrog kev hloov kho tshiab - uas yuav hloov pauv qhov kev ua tau zoo ntawm qhov no twb tau zoo, pob yooj yim. Peb nyiam Kenda's 25c Kriterium log tsheb txawm hais tias lawv yog qhov hnyav hnyav hauv daim ntawv hlau-beaded.
Nkauj
Ntau yam zoo li qhov siab dua-spec Speedster 40 peb tau sim qee lub hlis dhau los, 50 ua pov thawj tam sim ntawd punchy rau qee yam loj heev, thiab muaj peev xwm ua rau koj xav tsis thoob thaum koj tig lub wick. Nws tau ceeb toom rau peb cov tswv yim, teb eagerly rau qhov meest provocation, thiab lub hwj chim yog pw tsaug zog zoo los ntawm nws cov tawv alloy ncej.
Tsis muaj qhov tsis lees paub Speedster 50 yog qhov muaj txiaj ntsig zoo ntawm cov tsheb kauj vab aluminium-thav duab uas yuav ua tau zoo heev ntawm txoj kev du, tab sis peb tsis tuaj yeem pom ntau ntawm cov. Qhov hnyav ntawm txoj kev buzz kis tau los ntawm nws cov diav rawg alloy tsis cais tag nrho los ntawm tus tuav, thiab txawm hais tias nws tsis nyob hauv thaj chaw ntiv tes, txoj kev zoo tshaj plaws los hais txog qhov kev xav koj xav thaum caij Scott hla txoj kev pitted yog 'kev tawm tswv yim heev'. Qhov no tsis pab los ntawm lub kaum sab xis ntawm 74.2 °, thawb tus neeg caij tsheb mus rau qhov chaw uas koj pib coj qhov hnyav ntawm koj lub dab teg. Tab sis tos, qhov no suab zoo li peb tab tom muab lub tsheb kauj vab panning - muaj ntau dua rau nws. Kev teeb tsa nruj muaj qhov txiaj ntsig zoo ntawm kev ua qhov no yog ib qho ntawm cov tsheb kauj vab uas peb tau sim hauv cov nqi no. Nws tag nrho cov pawg yuav tsis yeej koj ib qho kev khiav mus rau saum toj ntawm lub zos nce toj, tab sis kev sib kis ntawm qhov sib piv los ntawm triple chainset thiab 11-30 cassette yog txaus rau feem ntau zaus, yog tias muaj feem cuam tshuam rau cov neeg caij tsheb tshiab.
Dua ntxiv, qhov nruj nruj rau pem hauv ntej kawg ua qhov zoo dua thaum koj muab cov fab rau hauv qhov sib npaug. Nws qhov kev ua haujlwm poob qis yog qhov tshwj xeeb tshaj plaws, ua rau koj flick Speedster los ntawm ib lub apex mus rau tom ntej hauv kev ntseeg siab. Tab sis thaum nws muaj ntau mus, nws yog lub chaw nres tsheb uas txhawj xeeb peb me ntsis. Muaj tsis txaus tom los ntawm Tektro brakes los ua kom peb muaj kev ntseeg siab kom tawm ntawm braking lig. Cov log tsheb Kenda Kriterium txhawb kev ntseeg siab, txawm li cas los xij, thiab peb yuav tsis maj hloov kho lawv. Tej zaum koj yuav xav tau kev sib tham nyuaj nrog Syncros Haiv Neeg 27 lub log, txawm li cas los xij, ua kua muag qhia rau lawv tias koj tau pom qhov sib dua, tsis yooj yim, hloov pauv hauv daim ntawv ntawm qee yam zoo li Mavic's £ 320 Ksryiums. Yog lawm, peb paub tias yog ib nrab ntawm tus nqi ntawm lub tsheb kauj vab, tab sis lub ntsiab lus yog tias Scott's thav duab yuav ua rau muaj kev sib tw zoo, thiab siav rau kev txhim kho. Koj tuaj yeem tsim lub stunner nrog me ntsis nyiaj ntxiv, tab sis qhov no yog vim li cas Scott muaj Speedster 20 thiab 30 hauv nws qhov ntau.
