I-Specialized ilahle umklamo wayo ojwayelekile yakhetha ukuhlala esihlalweni esiguquguqukayo nesiqondile.
Ubulungu bangaphandle bukhokhiswa minyaka yonke. Okubhaliselwe okuphrintiwe kutholakala kuphela kubahlali base-US. Ungakhansela ubulungu bakho nganoma yisiphi isikhathi, kodwa ngeke kube nokubuyiselwa kwemali ngezinkokhelo ezenziwe. Ngemva kokukhansela, uzokwazi ukufinyelela ubulungu bakho kuze kube sekupheleni konyaka okhokhelwayo. imininingwane eyengeziwe
Ngezinye izikhathi, ezinye zezinto ezintsha zakamuva embonini yamabhayisikili zibonakala zengeza ubunzima obukhulu kunalokho okufanele. Kodwa akuzona zonke izindaba ezimbi. Kukhona nemibono emihle yokwenza ibhayisikili libe lula futhi libe ngcono.
Ngezinye izikhathi umklamo omuhle ubuza ukuthi yini ongayidingi uma kuqhathaniswa nomklamo wokumiswa oyinkimbinkimbi kakhulu noma izinto ze-elekthronikhi ezengeziwe. Uma kukhulunywa kakhulu, ukulula kusho ukwenza amabhayisikili abe lula, athule, ashibhile, abe lula ukuwanakekela futhi athembeke kakhudlwana. Kodwa hhayi lokho kuphela. Isixazululo esilula siphinde sibe nobuhle nobuhlakani.
Ushintsho lushiye ipulatifomu elengayo ye-Spur esikhundleni sesistimu yokusekela elula nelula.
Kunesizathu sokuthi cishe wonke amabhayisikili e-XC manje ane-"flex pivot" esikhundleni se-pivot yendabuko enama-bearings noma ama-bushings. Ama-flex pivots alula, asusa izingxenye eziningi ezincane (ama-bearings, ama-bolts, ama-washers...) kanye nokugcinwa. Ngenkathi ama-bearings edinga ukushintshwa njalo ngesizini, ama-flex pivots aklanywe ngokucophelela azohlala isikhathi eside kufreyimu. Ama-pivots angemuva kohlaka, kungakhathaliseki ukuthi asezihlalweni noma ezihlalweni, ngokuvamile abona amazinga ambalwa okujikeleza ekuhambeni kwe-suspension. Lokhu kusho ukuthi ama-bearings angaqhekeka futhi aguge ngokushesha, kuyilapho amalungu ohlaka oluguquguqukayo enziwe nge-carbon, insimbi noma ngisho ne-aluminium angamukela kalula lolu hlu lokunyakaza ngaphandle kokukhathala. Manje avame ukutholakala emabhayisikilini anokuhamba okungu-120mm noma ngaphansi, kodwa ama-flex pivots ohambo olude enziwe, futhi ngicabanga ukuthi sizobona amaningi awo njengoba ubuchwepheshe bokukhiqiza buthuthuka.
Kwabagibeli bebhayisikili bezintaba abakhuthele, izinzuzo zokugibela ibhayisikili elilodwa zingase zibe sobala kangangokuthi cishe ziyabonakala. Zisivumela ukuthi sisuse ama-derailleurs angaphambili, ama-derailleurs angaphambili, izintambo kanye (ngokuvamile) neziqondiso zamaketanga, kuyilapho zisanikeza izinhlobo ezahlukene zamagiya. Kodwa kubagibeli abasafufusa, ukulula kwe-shifter eyodwa kuzuzisa kakhulu. Akukhona nje ukuthi kulula ukuyifaka nokuyinakekela, kodwa futhi kulula ukuyigibela ngoba udinga ukucabanga nge-shifter eyodwa kanye namagiya asatshalaliswa njalo.
Nakuba zingasha ngempela, manje usungathenga ama-hardtails asezingeni lokuqala anezitimela ezinhle ze-single-ring drivetrains. Lokhu kuyinto enhle kakhulu kumuntu osanda kuqala kulo mdlalo.
Ngiyaqiniseka ukuthi kuzoba nokugxekwa okuningi ukuvikela i-single pivot, kodwa nakhu. Kunezigxeko ezimbili zamabhayisikili ahamba nge-single pivot. Eyokuqala ihlobene nokubhuleka futhi isebenza kumabhayisikili ahamba nge-link ahamba nge-single pivot kanye namabhayisikili ahamba nge-single pivot angempela.
Isizathu esiyinhloko sokusebenzisa ukwakheka ku-single pivot eqhutshwa yi-link (okuyidizayini evame kakhulu namuhla) ukunciphisa nokulungisa isici sokulwa nokunyuka, okuwumphumela wamandla okubhuleka ekumisweni. Lokhu kuthiwa kuvumela ukumiswa ukuthi kuhambe ngokukhululeka phezu kwamaqhubu lapho kubhuleka. Kodwa empeleni, akuyona into enkulu. Eqinisweni, amanani ajwayelekile aphezulu okulwa nokunyuka kwama-single pivots ayawasiza ukuthi amelane nokucwila kwamabhuleki, okwenza azinze kakhulu lapho ebhuleka, futhi ngicabanga ukuthi umphumela ubonakala kakhulu. Kuhle ukusho ukuthi eminyakeni edlule, amabhayisikili e-single-axle aqhutshwa yi-linkage avela ezinkampanini ezifana nawo awine iNdebe Yomhlaba eminingi kanye nemijaho.
Ukugxekwa kwesibili kusebenza kuphela kumabhayisikili e-single-axle angempela, lapho ukushaqeka kufakwe khona ngqo engalweni yokushintsha. Ngokuvamile awanakho ukuqhubekela phambili kohlaka, okusho ukuthi noma yikuphi ukuqhubekela phambili noma "ukukhuphuka" kwesivinini sentwasahlobo kufanele kuvele ekushaqekeni. Ngokuxhumana okuqhubekayo, amandla okudambisa nawo ayanda ekupheleni kokushaqeka, okusiza kakhulu ukuvimbela ukuwela phansi.
Kuhle ukusho kuqala ukuthi eminye yemiklamo eyinkimbinkimbi kakhulu, njenge-Specialized's, ayithuthuki kakhulu kuneminye imishini yokujikeleza eyodwa. Futhi, ngemishini yomoya yesimanje, inqubo yokulungisa izipringi ngama-volume shims iyinto elula. Kuye ngokuthi ubuza bani, amazinga okunciphisa umswakama ancike ekushayweni yi-stroke avela ekuxhumaneni okuqhubekayo akuwona njalo into enhle. Yingakho ukwenza ibhayisikili elisehlayo elinesixhumanisi esiqhubekayo sokushayela intwasahlobo (ye-coil) kanye nesixhumanisi esiqondile sokushayela i-damper.
Kuyavunywa, ukuxhumanisa okuqhubekayo kungase kusebenze kangcono kwabanye abantu kanye nokushaqeka okuthile, kodwa ngokusetha kahle ukushaqeka, i-pivot eyodwa isebenza kahle ngempela. Udinga nje intwasahlobo eqhubekayo kanye/noma ukuwohloka okuncane. Uma ungangikholwa, ungafunda ukubuyekezwa okuhle kwamabhayisikili ahamba nge-single-pivot avela kwabanye abahloli lapha nalapha.
Noma kunjalo, ngicabanga ukuthi ukuxhumanisa okuqhubekayo ngokuvamile kungcono ngokombono wokusebenza. Kodwa ngama-shocks afanele, ama-single pivots asebenza kahle kakhulu kulabo kithi abangebona abaqhawe abahlaselayo, futhi ukushintshana okulula kokuthwala kubenza babe ukukhetha okunengqondo kulabo abahamba odakeni oluningi.
Kunezindlela eziningi eziyinkimbinkimbi zokuzama ukuthuthukisa ukusebenza kokumiswa: ukuxhumanisa okuhle, ama-shock absorber abizayo, ama-idlers. Kodwa kunendlela eyodwa kuphela eqinisekile yokusiza ibhayisikili ukuthi libushelelezi: linikeze ukuhamba okwengeziwe kokumiswa.
Ukwengeza uhambo akugcini nje ngokungeza isisindo, izindleko, noma ubunzima, kodwa kushintsha kakhulu indlela ibhayisikili elimunca ngayo ukushaqeka ngempumelelo. Nakuba kungebona bonke abantu abafuna uhambo olugoqekile kahle, ungagibela ibhayisikili lakho olithandayo lebanga elide ngokunciphisa ukugoba, ukusebenzisa ukukhiya ngaphandle, noma ukwengeza izikhala zevolumu, kodwa awukwazi ukuhamba nawe njengebhayisikili elithambile lohambo olufushane.
Angisho ukuthi wonke umuntu kufanele agibele ibhayisikili elikhuphukayo, kodwa ukunikeza ibhayisikili elingcolile ukuhamba okungaphezulu ngo-10mm kungaba lula futhi kuphumelele kakhulu ekuthuthukiseni ukulandelela, ukubamba, kanye nenduduzo kunomklamo wokumiswa oyinkimbinkimbi.
Ngokufanayo, kunezindlela eziningi eziyinkimbinkimbi zokuthuthukisa ukusebenza kokubhuleka, njenge-rotors eziphefumulayo, i-rotors ezinezicucu ezimbili, ama-brake pad ane-finned, kanye nama-lever cams. Iningi lalawa lengeza izindleko futhi ngezinye izikhathi izinkinga. Ama-Fin pad avame ukukhenceza, futhi ama-lever cams angakhulisa ukungahambisani noma ukuyekethisa ohlelweni lwe-hydraulic.
Ngokuphambene nalokho, ama-rotor amakhulu athuthukisa amandla, ukupholisa kanye nokuvumelana ngaphandle kokwengeza ubunzima. Uma kuqhathaniswa nama-rotor angu-200mm, ama-rotor angu-220mm azokwandisa amandla cishe ngo-10% ngenkathi enikeza indawo engaphezulu yokususa ukushisa. Yebo, anzima kakhulu, kodwa endabeni yama-rotor, ama-disc anesisindo esingamagremu angu-25 kuphela, futhi isisindo esengeziwe sisiza ekumunceni ukushisa ngesikhathi sokubhuleka okunzima. Ukuze wenze izinto zibe lula, ungazama ama-rotor angu-220mm namabhuleki amabhodwe amabili esikhundleni sama-rotor angu-200mm namabhuleki amabhodwe amane; amabhuleki ama-piston amabili kulula ukuwanakekela futhi kufanele afane ngesisindo nangamandla.
Angifuni ukunikeza umbono we-Luddite. Ngithanda ubuchwepheshe obenza ibhayisikili lisebenze kangcono, noma ngabe liyingxenye encane nje. Ngingumlandeli omkhulu wezigxobo ze-dropper zokuhamba ibanga elide, amakhasethi angu-12-speed, ama-insert amathayi, kanye nezipringi zomoya ezinamandla aphezulu ngoba zinikeza izinzuzo ezibonakalayo. Kodwa lapho umklamo onezingxenye ezimbalwa usebenza kahle ezweni langempela, ngingathanda ukusebenzisa indlela elula njalo. Akukhona nje ukonga amagremu ambalwa noma imizuzu esitolo; ikhambi elilula nelanelisayo lingaphinde libe lihle futhi libe lihle kakhulu.
Bhalisa ukuze uthole izindaba zakamuva, izindaba, ukubuyekezwa kanye nezipesheli ezikhethekile ezivela ku-Beta kanye nemikhiqizo yethu ehambisanayo, ezilethwa ebhokisini lakho lokungenayo.
