Teem tau ntawm ib tug gearshift rau lub tsheb tuam. Ceev cycling

Nws yog li ntawd ntau buyers uas yuav koj tus kheej ib lub tsheb tuam rau thawj lub sij hawm, twb tsis paub yog vim li cas nws yuav tsum tau kis tau tus mob thiab yuav ua li cas lawv yog teeb. Muaj yog ib tug stereotype hais tias cov nyiaj ntau uas thauj speeds, li ntawd, nws yog ntau tus neeg sawv cev thiab zoo. Ib tug paradox nyob rau tom qab ntawm xws fallacies zoo cyclist uas nyob rau saum toj rau lub kawg haum rau no hloov lwm lub tsev thaum pedaling nyuaj heev thiab txhua txhua centimeter yog muab nrog teeb meem loj. Txawm hais tias nws yog tej zaum tau mus soj ntsuam thiab hais tias qhov teeb meem no: tus uas caij tus yoov lub roob thiab NW nyuam qhuav khaws cia PACE nrog lub taw ntawm rods thiab ib tug system khiav hauj lwm rau cov uas tsis muaj kev ceev.

Purpose iav

Nyob rau hauv thiaj li yuav kam nrog xws li ib tug coj txawv txawv qhov teeb meem, nws yog tsim nyog los nkag siab txog dab tsi yog yuav tsum tau mus kom lub tsheb kauj vab thiab thaum lawv siv yog tsim nyog. Txawm li cas los, qhov no yuav tsum ua me ntsis txog cov lub sij hawm "cadence" - lub pom pedaling zaus. Cadence yog muab faib ua ob peb hom:

• siab;
• tsawg;
• pom.

Nyob rau ib lub high school cov rider muaj Pedal thiab feem ntau, uas ua rau yus muaj zog buildup nyob rau hauv lub eeb thiab ib tug misallocation ntawm lub dag zog. Tshwj xeeb yog mob no disadvantage muaj, yog ib tug cyclist tsis txhob siv cov pedal los yog hu rau tuklipsy, uas yuav txhim kho tau txoj hauj lwm ntawm tus taw nyob rau hauv qhov tseeb txoj hauj lwm.

Thaum lub cadence yog tsawg tsawg, cov pedals yog yam heev maj mam. Rau kis loj yuav tsum siv zog. Cov lus nug tshwm sim: "Yog vim li cas, ces, pem hauv ntej ceev shifter rau lub tsheb kauj vab yog hais tias nws yog tsis siv?" Tag nrho cov ntau li ntawd thaum koj tsiv mus nyob rau hauv no hom yog nkees heev nqaij, nce lub load rau ntawm cov pob qij txha, uas yuav ua tau kom cov kab mob ntawm lub licas.

Pom zoo khiav hauj lwm tej yam kev mob

Lub pom cadence qhia judicious siv biker rog nyob ntawm seb nws ib tug neeg tus yam ntxwv, qhov hnyav thiab hom nyem rau ntawm cov av. Rau lub tiaj nruab nrab tus nqi ntawm nws yog nyob rau hauv lub chav los ntawm 80 mus 110 revolutions ib feeb. Raws sij hawm cycling ceev pauv rau lub tsheb kauj vab (Shimano, Sram, los yog analogs thereof), lub cyclist pom tau tias nyiam, tab sis nws tseem tswj tus nqi ntawm cov pom zoo cadence rau lub computer. Nws yog nyob rau hauv no hom, tus neeg pom tau tias nyiam thiab tusyees haus lawv tus kheej lub zog.

iav ua haujlwm

thiab ib tug lub sij hawm ntawd thaum lub ceev hloov yog ua qho tseem ceeb heev. Iav hloov yuav tsum tau ua los ntawm ib tug thiab thaum lub sij hawm lawv hloov mus muab ib tug me me load rau hauv lub pedal. Qhov no yuav tiv thaiv tau kev puas tsuaj rau lub saw tensioner thiab kom lawm lub tsheb kauj vab qhov chaw yog ceev selector yuav ua rau muaj ntau yam teeb meem rau beginners thiab txawm ua rau nyiaj txiag them nqi. Tom qab tag nrho, nyob rau kev nkag mus rau ib tug ntxhab sawv ntawm siab uas yuav muaj, tsis tau tsuas yog kom tau ib tug raug mob loj, tab sis kuj coj nws cov hlau phooj ywg tsev nyob rau hauv nws caj npab. Tshwj xeeb tshaj yog feem ntau xws teeb meem tshwm sim thaum uas siv cov kev nkag teb chaws-theem cov khoom tsis muaj ib tug tseem ceeb paj tau paj ntawm kev ruaj ntseg. Xav txog cov hauv paus ntsiab lus ntawm nws cov lag luam thiab debugging.

Nta chaw ceev connectivity system

Rau beginners hloov hloov kev ceev ntawm lub tsheb kauj vab - nws yog ntuj raug txim. Txawm tias muaj tseeb hais tias qhov no mechanism yog uncomplicated txhua yam system, nws yog heev xav tau mus rau lub nuances. Yog li ntawd, ua ntej pib ua hauj lwm, nws yog ib qho tseem ceeb kom paub tseeb tias cov pem hauv ntej thiab nram qab lub derailleur yog zoo, thiab cov saw ntaub ntawv txoj cai cheynlayn ntawm cov hnub qub. Kev txiav txim ntawm cov tsis yog ua li cas tsis pom kev. Ua li no, tig lub tsheb tuam upside down thiab xyuas nws rov qab - los ntawm cwjmem thiab mus txog rau lub hauv qab bracket. Ceev selector yuav tsum tau securely fastened tshaj lub bracket, thiab cov saw hlau, uas yog nyob rau nws chais, yeej tsis xav mus thiab lubricated nrog haum cov ntaub ntawv muab nws zawv zawg thiab tsawg coj. Siv imagined kab nruab nrab ntawm cov pem hauv ntej thiab nram qab lub hnub qub. Yog hais tias nws ntog rau lawv chaw, lub system Cheebtsam yog zoo kom thiab installation ntawm lub tog raj rings yog tsis yuav tsum tau. Yog hais tias lub cai teeb meem no yog diametrically opposite, nws yog tsim nyog los tshem tawm nws, qhov no yuav tsum tau teem ib lub gearshift rau lub tsheb tuam.

Indirect ua ntawm nws unsatisfactory lag luam tej zaum yuav ua tau ib tug hlua txuas lub bracket los ntawm tus tiv thaiv lub tsho. Tom qab tag nrho, yog hais tias nws yog xeb, thiab yog tsis muaj lubrication, koj yuav muaj kev nyuaj nyob rau hauv kev khiav hauj lwm qhov system raws li ib tug tag nrho. Xws li ib tug teeb meem no yuav tshwm sim, thiab thaum twg nws creases thaum dua lub nyias hlua uas yuav stopper vim tshaj kev sib txhuam.

Muaj peb yam tseem ceeb theem ntawm debugging, lub kev tsis saib xyuas uas yuav tsis tso cai rau koj los customize txoj kev hloov cov kev ceev. Cov yuav tsum muaj xws li cov mob ntawm lub txuas cable, lub chaw ntawm cov ntsia hlau, uas yog ua los ntawm ib tug gearshift chaw nyob rau hauv lub tsheb kauj vab, thiab cov lag luam los ntawm ib tug caij nplooj ntoos hlav-loaded tensioning mechanism.

Tiv tsho thiab cable

Debugging no lub cuab tam plays ib qho tseem ceeb luag hauj lwm. Cable txuas lub bracket rau tus tes hloov qhov, yog nyob ntawm nws, yog ua iav hloov nrog ib co siab. Nyob rau tib lub sij hawm nws saib kuas tseeb txoj hauj lwm ntawm lub saw rau lub chais thiab cov hnub qub. Yog hais tias lub cable nro yog ntev li, ces tus kis tau tus mob tej zaum yuav plam ib tug ob peb notches los yog hloov. Yog hais tias nws tsis muaj zog, ces tus ua ntawv thov kev quab yuam yuav tsis txaus mus ua mechanism - thiab tsis muaj dab tsi yuav tshwm sim.

kho screws

Thaum ib tug gearshift yog ua qhov chaw kawm no, lawv muab cov kev kawm hauj lwm nyob rau hauv cov saw hlau chais thiab daig kab hnub qub rods. Lub sab sauv screws yog feem ntau lub luag hauj lwm rau tes hloov qhov offset mas upwards, thaum lub tsawg - down. Haum ntawm lawv txoj haujlwm yog ua li cas nrog rau ib qho Allen tseem ceeb. Nyob rau hauv ib tug piv txwv, nws yuav zoo raws li nram no: thaum cov hniav ntawm overshoot saw daig kab yuav tsum muab nws txo qis down mechanism rau txhim khu kev qha coupling. Nyob rau hauv rooj plaub no tus qis yob muab intimate hu ntawm tus tsav ntsiab. Yog hais tias nyob rau hauv Circuit Court ib co kua nplaum, muaj zog coj, tab sis nws yog tsim nyog los nqa tawm qhov rov qab kev txiav txim thiab tsis muaj zog sis.

teem tensioner

Qhov no lub caij muab cov nyiaj tsawg nyuaj thaum ib tug gearshift yog ua chaw rau lub tsheb tuam. Feem ntau nws tsis yuav tsum tau kho cov ntsia hlau cuam tshuam, tiam sis tej zaum vim kev tsis ncaj ncees nyob rau hauv cov huab txoj hauj lwm nws yuav ua rau kom lub ntaus thiab ceev coj ntawm lub sab sauv log thiab saw. Txiav txim siab los ntawm nws sib ntswg los yog txhav tas Grover.

Yog hais tias tom qab siv lub tswv yim pom zoo ntawm qhov zoo tshwm sim yog tsis tiav, nws yog tsim nyog los tig mus rau ib tug tsim nyog lub tsheb kauj vab kws kho tsheb uas yuav daws tau koj qhov teeb meem.
