Knight 65s yog cov roj carbon ceev ceev uas tuaj yeem yog tus uas yuav tau txais Zipp 404
Txawm tias nyob hauv lub ntiaj teb jaded ntawm kev sim tsheb kauj vab peb tseem tau txais kev xyiv fab tshwj xeeb los ntawm kev hnov cov hum ntawm qhov sib sib zog nqus cov roj carbon log. Nws yog qhov nyuaj heev los piav txog lub suab hauv prose. Peb ua qhov kev xav zoo, tab sis nws tau sau qee yam xws li 'wummhh wummhh wummhh'. Ib txhia hais tias nws yog lub suab ntawm cov bearings amplified los ntawm lub loj echo chamber tsim los ntawm lub hollow carbon rim - peb hais tias nws yog lub suab ntawm ceev thiab yog hais tias peb yuav tsum ntsuas peb ceev tag nrho ntawm lub suab, ces lub Knight 65s yog ib co suab nrov log.
Txawm hais tias Knight Composites yog cov neeg ua si tshiab hauv kev lag luam aerodynamic log, cov neeg tom qab lub hom muaj kev paub ntau heev. Ob tus neeg koom tes, Jim thiab Beverly, muaj ntau tshaj 30 xyoo ntawm kev sib xyaw ua haujlwm nruab nrab ntawm lawv suav nrog lub sijhawm siv ntawm Reynolds, qhov twg Jim tau pab tsim Ouzo diav rawg, thiab ENVE raws. Kevin Quan tseem koom nrog Knight tau ua haujlwm rau Cervelo, qhov chaw nws tsim P3C lub sijhawm sim ua haujlwm, nrog rau lwm tus xws li Parlee thiab Neil Pryde.
Knight 65 rims yog bang ntawm kev sib tw nrog fatter rounded profile nyiam los ntawm ntau lub npe loj. Qhov no yuav tsum yog aerodynamic ntau dua li yav dhau los tsim txawm hais tias nws tsis yog tsis muaj teeb meem. Lub nres calipers ntawm Cov Ntaub Ntawv Pawg peb tau siv los ntsuas lub log yog txoj cai ntawm qhov txwv ntawm qhov dav npaum li cas lawv tuaj yeem mus kom haum rau cov rims.
Vs Zipp 404
Knight thov tias lub npoo tsim 20% tsawg dua hauv lub qhov cua tshaj nws cov neeg sib tw ze tshaj plaws, thiab 10% tsawg dua thaum haum rau tus ncej. Peb tab tom kwv yees nws cov neeg sib tw ze tshaj plaws yog Zipp 404 yog li nws tsim nyog kos qhov kev sib piv nrog lawv (nws kuj yog ib qho ntawm feem ntau aero wheelsets peb pom ib ncig). Ncaj nraim nws tseem ceeb heev uas yuav tsum nco ntsoov tias Knights yog 7mm tob dua li ntawm 404s (65mm vs 58mm) yog li nws tsis tsim nyog xav kom 65s ua tau zoo dua.
Knight muab lawv cov txiaj ntsig aerodynamic nqis mus rau qhov zoo ntawm cov neeg uas ua rau lawv cov rims. Knight paub tias muaj kev siv thev naus laus zis ntau dua nyob rau ntawd nrog carbon fiber, yog li nrhiav siv nws rau kev tsim cov log sib xyaw. Lub hom phiaj tsis tau mus rau ib qho aerodynamic gimmicks lossis cov qauv tsim tshwj xeeb, tab sis theej thov tias cov duab meej ntawm lub npoo yog qhov tseem ceeb tshaj aerodynamic ntawm txhua lub ces kaum ntawm yaw.
Knight tsis tsim ib qho ntawm lawv tus kheej hubs, es tsis txhob xaiv koom tes nrog ntau lub tuam txhab. Cov txheej peb muaj nyob rau hauv kev xeem tuaj nrog DT Swiss 240, tab sis lawv kuj muaj nrog lub sib dua thiab ceev dov 180 hubs. Peb txheej ntawm 65s hnyav ntawm 1,610g (tsis muaj daim kab xev), uas yog 10g sib zog dua ib khub Zipp 404s. Yog hais tias koj xav txog qhov tseeb lawv yog 7 hli tob dhau lawm nws yog ib tug zoo kawg nkaus headline daim duab. Nrog DT Swiss 180 hubs lawv poob mus rau 1, 573g thiab insane 1, 377g nrog Aivee SR5 hubs. Tom qab ntawd muaj tus nqi ntawm chav kawm - Knight 65s nrog 240 hubs yog £ 1648 piv rau Zipp 404s £ 2679. Ntawm daim ntawv tsawg kawg, nws nyuaj rau xav txog vim li cas koj thiaj xaiv lwm yam, tab sis ua li cas ntawm daim ntawv thiab ntawm txoj kev?
Nkauj
Kev sim aero log yog ib txwm nyuaj vim tias koj qhov nrawm tuaj yeem cuam tshuam los ntawm ib puag ncig - uas tau hais tias, peb tsis paub leej twg mus caij tsheb hauv qhov cua cua yog li nws yog txoj hauv kev tsim nyog tshaj plaws. Tawm ntawm txoj kev tsis tu ncua Knight 65s yob nrog zoo. Kev hloov pauv nrawm yog ib txwm yog thawj qhov koj pom ntawm lub log tshiab thiab Knights nrawm nrawm, tab sis lawv tsis zoo. Lawv muaj zog txaus tab sis thaum kawg ntawm hnub lawv nyob sib sib zog nqus seem carbon log ces hnyav me ntsis ntawm ntug.
Tshaj rau lawv yog qhov zoo, lawv tsis qeeb koj tab sis lawv tsis muab kev txhawb zog rau koj. Yuav kom tau txais qhov zoo tshaj plaws ntawm cov log no koj yuav tsum tau ua kom lawv ceev. Muaj txoj kev ncaj ntev uas peb nyiam ua kom tiav peb cov kev caij tsheb thiab nrog rau 65s ntawm, rhuav tshem nws ntawm peb qhov kev ceev ib txwm ua tau yooj yim dua. Nws tuaj yeem ua tau nrawm heev ntawm txoj kev ntawd, thiab peb tau muaj qee lub sijhawm txhawj xeeb nrog cov log sib sib zog nqus, tab sis Knights tau coj zoo. Tseem muaj qhov khib maj nrawm tab sis peb tsis xav tias nws yog qhov ntau tshaj li qhov koj tuaj yeem xav tau ntawm ob lub log qis. Braking ntawm lub 65s yog par rau chav kawm nrog carbon fiber, txawm hais tias lawv muaj ib tug nyiam squeal nyob rau hauv tiag tiag braking.
Qhov kev sim loj uas peb tau muab rau 65s yog coj lawv mus rau lub sijhawm sim. Nws yog ib qho nyuaj, twisty Circuit Court yog li tej zaum tsis yog qhov zoo tshaj plaws kev sim hauv av (piv rau txoj kev A) tab sis nws tau muaj ib ntu ntev kom muab lub log rau txoj kev mus. Ua kom nrawm tawm ntawm cov ces kaum thiab nce toj, peb pom peb tus kheej xav tias peb muaj 1,000g super lub teeb log tab sis sai li sai tau thaum peb nkag mus rau sab nraub qaum ncaj lub log tuaj rau hauv lawv tus kheej. Peb muaj peev xwm ua tau yooj yim caij nkoj ntawm 40kph + thiab nws yog qhov uas peb tau ua feem ntau ntawm peb lub sijhawm. Nws yog ib qho nyuaj los qhia tias qhov ntawd yog dab tsi, txawm hais tias lub aerodynamic zoo ntawm lub log los yog cov nyhuv flywheel ntawm cov rims hnyav dua tab sis peb yeej tsis tau xav tias xis nyob nrog kev ceev nrawm.
Tseem muaj ob peb me me blips mus nrog lub log ho. Cov skewers suav nrog yog cov tawv heev thiab qee zaum nyuaj kom tau qhov nro txoj cai, thiab tau lub log rau hauv. Peb feem ntau pom tias peb tau muab lawv xoob heev vim tias lub skewer tsuas yog tawv heev. Lwm qhov teeb meem yog nrog cov hubs, thiab txawm hais tias qhov ntawd tsis yog Knight qhov txhaum nws tseem mob. Thaum kawg ntawm qhov kev sim cov sprockets tau txiav tsis zoo rau hauv lub freehub lub cev ua rau nws nyuaj heev kom tshem tawm cov cassette yog li peb muaj kev txhawj xeeb txog lub neej ntev ntawm DT Swiss freehub.
Ntawm daim ntawv no lub log yog qhov kev yuav khoom zoo thiab lawv tseem yog qhov kev yuav khoom zoo hauv ntiaj teb tiag.
