Lub Merida Reacto 5000 yog riam phom aero nrog tag nrho cov mos txwv txoj cai: ceev, kev ua haujlwm thiab kev nplij siab
Luam cov geometry ntawm lub tsheb kauj vab siv los ntawm cov nyiam ntawm Rui Costa ntawm Lampre-Merida World Tour team, Merida Reacto 5000 yog lub tsheb kauj vab aero nrog cov ntawv pov thawj sib tw. Ncej raj tsim nyob rau hauv cov cua qhov los ntawm Taiwanese chaw tsim tshuaj paus ua ke nrog aero cov ntsiab lus los ua ib lub tsheb kauj vab tsim rau siab tshaj plaws ceev, efficiency thiab kev nplij siab. Koj xav tau dab tsi ntxiv? Cov lus nug yog: nws puas tuaj yeem ua raws li cov lus cog tseg ntawm kev ua 'txhua tus neeg caij tsheb kauj vab'? Thiab ua Ultegra Cheebtsam gel nrog rau lwm cov khoom siv los tsim kom muaj kev sib koom ua ke?
Frameset
Daim ntawv teev npe ntawm cov cuab yeej siv thev naus laus zis ntawm Merida lub vev xaib tuaj yeem siv qhov chaw ntawm tag nrho cov kev sim no los piav qhia kom raug. Cov ncauj lus tseem ceeb, txawm li cas los xij, yog NACA Fastback tube profiles rau aerodynamic efficiency; ib tug S-Flex seatpost, nrog ib tug rubberised seem rau dampen txoj kev vibrations; Bio-Fiber Damping, uas siv flax fibers woven rau hauv carbon thav duab los pab nrog vibe cais, thiab lub taub hau flip-flop tso cai rau kev hloov ntawm lub rooj zaum lub kaum sab xis ntawm 3 ° ntau.
Lub thav duab geometry tswj hwm nws qhov kev sib tw-npaj, nrog 73 ° lub taub hau lub kaum ntse ntse (uas peb ntsuas ntawm qis qis qis-steering 72.3 °), luv wheelbase thiab 136mm lub taub hau raj tso cai rau koj kom qis dua pem hauv ntej, tshwj xeeb tshaj yog ib zaug lub slammed.
Cov kab iav sab hauv yog ua kom zoo zoo los ntawm cov raj sab saum toj los ntawm cov lus qhia saum toj kawg nkaus-mounted cable. Ob lub rear thiab pem hauv ntej mech cables muaj chim adjusters, thiab lub rear nres cable muaj ib tug inline ceev tso rau lub direct-mount calliper.
Cov ntsiab lus
Lub Merida siv Ultegra rau kev hloov pauv thiab mechs, tom qab ntawd sib xyaw ntawm cov kab qis Shimano thiab FSA cov khoom siv. Ib qho 11-28 105 cassette yog sib npaug rau FSA Gossamer Pro mid-compact, 52/36 chainset uas muab 57g rau qhov sib npaug Shimano Ultegra unit. Braking yog saib xyuas los ntawm direct-mount 105 callipers. Nrov ntawm aero tsheb kauj vab, thiab txawm ua rau lawv txoj kev mus rau kev nce toj-txheej txoj kev tsheb kauj vab xws li Trek's siab-kawg Émondas, direct-mount callipers tau haum rau hauv rab rawg thiab yog li ntawd ze rau tus ncej. Qhov kev teeb tsa nruj dua no muaj kev sib zog ua kom nrawm dua, qhov zoo dua aero me me, thiab chav rau cov log tsheb dav dua. FSA Gossamer compact alloy handlebars yog tuav los ntawm 100mm Merida-branded ControlTech qia, thaum nyob rau tom qab kev sib cuag taw tes, Merida's aero carbon flex seatpost yog topped nrog tob padded Prologo Kappa 2 eeb. Fulcrum's 35mm sib sib zog nqus-section Racing Quattro log tau pom nyob rau ntawm qhov kawg thiab, zoo li Norco's Easton EA70s, hnav Continental 25c Grand Sport tyres.
Nkauj
Rau tag nrho Reacto 5000's aero tube profiles, kev caij tsheb dhau - thiab xav tsis thoob - thawj qhov kev xav yog ntawm lub tsheb kauj vab uas yooj yim heev. Cov rooj zaum flared thiab chainstays, ua ke nrog Merida lub rooj zaum hloov tau, ua txoj haujlwm zoo ntawm kev sib cais ntawm kev vibrations los ntawm txoj kev ntxhib. Ntxiv rau, lub eeb Prologo, thaum tsis yog qhov yooj yim tshaj plaws ntawm plaub lub tsheb kauj vab peb tau sim ntawm no, yog nyob deb ntawm qhov zoo tshaj plaws padded.
Lub tsheb kauj vab zoo li tau rub tawm qhov ua kom yuam kev ntawm kev nplij siab zoo tib lub sijhawm raws li kev nruj nruj, qhov kawg ntawm qhov uas pom tseeb thaum koj sawv ntawm lub perch thiab muab txhua yam koj tau txais rau txoj kev sprint. Lub Fulcrum Quattro lub log yog qhov kev xaiv zoo, tab sis peb tau txais qhov kev xav tias lawv qhov siab radial nruj ua rau lub caij hnyav dua li nws tuaj yeem ua rau txoj kev choppier. Ntxiv rau, lawv qhov hnyav 1, 720g txhais tau tias lawv tsis nrawm nrog kev sib tw sib tw nrawm, ib yam nkaus. Hais tias, nyob rau hauv crosswinds, qhov twg koj yuav xav tias slab-sided aero thav duab raj thiab sib sib zog nqus rims raug kev txom nyem, lub Reacto effortlessly nce mus rau qhov kev sib tw.
Nws tsis yog tus neeg nce siab phem, txawm li cas los xij, tshwj xeeb tshaj yog thaum tackling ib qho chaw nce toj hauv lub eeb. Lub mid-compact chainset tsis muaj ntau yam kev nce toj siab uas muaj los ntawm Norco Valence SL, tab sis nws tsim nyog rau feem ntau luv luv nce. Qhov tseem ceeb ntawm no yog cov khoom sib txuas ntawm lub dav hauv qab bracket thiab chunky nyob twj ywm, ua ke nrog cov khoom zoo nkauj ntawm tus neeg caij tsheb sib tiv tauj. Nws tsis muaj qhov yooj yim ntawm kev hloov pauv hauv kev thauj khoom uas ob qho tib si Vitus thiab Norco muab. Tej zaum FSA chainset tsis yog qhov sib txuam zoo rau cov hloov pauv raws li Ultegra chainrings thiab cranks tej zaum yuav yog, tab sis cov cranks yeej nruj txaus thaum lub iav koom nrog.
Thaum lub caij muaj kev xav ntau dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qis qis, Reacto teb rau kev hloov pauv me me hauv txoj hauv kev uas nthuav tawm nws cov DNA sib tw. Nws tsis yog los ntawm txoj kev twitchy, tab sis yog heev teb thaum caij npau taws. Peb yuav tsum tsis txhob luv luv hais tias 'exhilarating', tab sis nrog tag nrho cov muaj spacers saum lub qia thiab tag nrho cov kev cog lus ntawm cov tee, muaj cov hnab ntawm kev zoo siab yuav tsum muaj.
Txawm li cas los xij, muaj qee qhov yws yws. Lub rooj zaum sib koom ua ke (nrog rau nws cov kab txuas txuas txuas txuas rau lub rooj zaum) yog fiddly los kho, txawm tias nws muaj txiaj ntsig zoo aerodynamically. Thiab qhov ncaj-mount rear nres, nyob rau hauv qab lub hauv qab bracket tsis tom nrog tej lub zog tsim nyog, txawm hais tias nws muaj ib tug aero kom zoo dua.
