Abakhethekile balahle idizayini yabo evamile bavuna isihlalo esiguquguqukayo se-pivot.
Ubulungu bangaphandle bukhokhiswa minyaka yonke.Okubhaliselwe kokuphrinta kutholakala kuphela kubahlali base-US.Ungakhansela ubulungu bakho noma nini, kodwa ngeke kube nokubuyiselwa kwemali ngezinkokhelo ezenziwe.Ngemva kokukhansela, uzokwazi ukufinyelela ubulungu bakho kuze kube sekupheleni kokukhokhwa. unyaka.imininingwane eyengeziwe
Ngezinye izikhathi, ezinye zezinto ezintsha zakamuva embonini yamabhayisikili zibonakala zengeza ubunkimbinkimbi obungaphezu kobufanele.Kodwa akuzona zonke izindaba ezimbi.Kukhona nemibono emihle yokwenza ibhayisikili libe lula futhi libe ngcono.
Kwesinye isikhathi idizayini enhle ibuza ukuthi yini ongayidingi uma kuqhathaniswa nomklamo wokulengiswa oyinkimbinkimbi kakhulu noma izinto zikagesi ezingeziwe.Ezinhleni zakho, ukuba lula kusho ukwenza amabhayisikili abelula, athule, ashibhile, agcineke kalula futhi athembeke.Kodwa hhayi lokho kuphela.Isixazululo esilula futhi inobuhle nobuhlakani obuthile.
Inguquko ilahle inkundla emisiwe ye-Spur ukuze ivune isistimu yokusekela enwebekayo elula.
Kunesizathu sokuthi cishe wonke amabhayisikili e-XC manje “sene-pivot eguquguqukayo” esikhundleni se-pivot yendabuko enama-bearings noma ama-bushings. ishintshwa njalo isizini, ama-flex pivots aklanywe ngokucophelela azohlala impilo yohlaka.Ama-pivots angemuva kohlaka, kungakhathaliseki ukuthi asezindaweni zokuhlala noma ama-chainstays, ngokuvamile abona amadigri ambalwa okuzungezisa ohambweni lokumiswa.Lokhu kusho ukuthi ama-bheringi angaboboka. futhi iguge ngokushesha kakhudlwana, kuyilapho amalungu ozimele aguquguqukayo enziwe ngekhabhoni, insimbi noma i-aluminium ingakwazi ukuthwala kalula lolu hlobo lokunyakaza ngaphandle kokukhathala. Manje avame ukutholakala emabhayisikili anohambo oluyi-120mm noma ngaphansi, kodwa ama-flexible pivots ahamba isikhathi eside sekwenziwe, futhi ngisola ukuthi sizobona eziningi zazo njengoba ubuchwepheshe bokukhiqiza buthuthuka.
Kubagibeli bamabhayisikili basezintabeni abashisekayo, izinzuzo zendlela ngayinye zingase zibonakale ngokucacile. Zisivumela ukuthi sisuse ama-derailleur angaphambili, ama-derailleur angaphambili, izintambo kanye (ngokuvamile) neziqondiso zamaketanga, kuyilapho sisahlinzeka ngamagiya ahlukahlukene. abagibeli bezimfundamakhwela, ubulula be-shifter eyodwa buyasiza kakhulu.Akukhona nje ukuthi kulula ukuzifaka nokuyinakekela, kodwa futhi kulula ukuzigibela ngoba udinga kuphela ukucabanga ngesishifu esisodwa kanye namagiya asakazwa ngokuqhubekayo.
Nakuba zingezintsha ncamashi, usungakwazi manje ukuthenga ama-hardtails ezinga lokungena anama-drivetrains e-single-ring ahloniphekile.Lokhu kuyinto enhle kakhulu kumuntu osanda kuqala kwezemidlalo.
Ngiyaqiniseka ukuthi kuzoba nokugxeka okuningi ukuze kuvikelwe i-pivot eyodwa, kodwa nakhu sihamba.Kunokugxeka okubili kwamabhayisikili ephivothi eyodwa.Okokuqala kuhlobene nokubhuleka futhi kusebenza kumabhayisikili e-pivot ashayelwa isixhumanisi njenge kanye namabhayisikili e-pivot eqiniso.
Isizathu esiyinhloko sokusebenzisa isakhiwo ku-pivot eyodwa ecushwe isixhumanisi (okuwumklamo ovame kakhulu namuhla) ukunciphisa nokulungisa isici esimelene nokuphakama, okuwumphumela wamandla okubhuleka ekumisweni. Lokhu kuthiwa kuvumela ukumiswa. ukuhamba ngokukhululeka phezu kwamaqhubu lapho ubhuleka.Kodwa empeleni, akuyona into enkulu.Eqinisweni, amanani ajwayelekile aphezulu okulwa nokukhuphuka kwama-pivots angawodwa awasiza ukuthi amelane ne-brake dive, awenze azinze kakhulu ngaphansi kwebhuleki, futhi ngicabanga ukuthi. umphumela ugqame kakhulu.Kufanele ukubalula ukuthi ngokuhamba kweminyaka, amabhayisikili ane-asi eyodwa ashayelwa ngokuxhunywa ezinkampanini ezinjengokunqobe izindebe zomhlaba eziningi nemijaho.
Ukugxekwa kwesibili kusebenza kuphela emabhayisikili eqiniso ane-asi eyodwa, lapho ukushaqeka kugibezwa khona ngokuqondile ku-swingarm. Ngokuvamile awanakho ukuqhubekela phambili kohlaka, okusho ukuthi noma yikuphi ukuqhubekela phambili noma “ukukhuphuka” kwesilinganiso sentwasahlobo kufanele kuqhamuke nokushaqeka.Ngokuxhunyaniswa okuqhubekayo , amandla okudambisa nawo anda ekupheleni kwe-stroke, okusiza nakakhulu ukuvimbela ukwehla.
Kuyafaneleka ukukhomba kuqala ukuthi eminye yemiklamo eyinkimbinkimbi, njenge-Specialized's, ayithuthuki kakhulu kunezinye i-pivots eyodwa.Futhi, ngokushaqeka komoya kwesimanje, inqubo yokulungisa iziphethu ezinamashimu evolumu iwucezu lwekhekhe.Kuya ngokuthi ungubani buza, amazinga okuncibilika ancike ku-stroke ekuxhumaneni okuqhubekayo akusiyo into enhle ngaso sonke isikhathi.Yingakho yenza ibhayisikili elehlayo elinesixhumanisi esiqhubekayo ukushayela intwasahlobo (ikhoyili) kanye nesixhumanisi somugqa ukushayela umswakama.
Kuyavunywa, ukuxhumana okuqhubekayo kungase kusebenze kangcono kwabanye abantu nokushaqisa okuthile, kodwa ngokusethwa kokushaqeka okulungile, i-pivot eyodwa isebenza kahle ngempela. Udinga nje intwasahlobo eqhubekayo kanye/noma ukuntengantenga okuncane. Uma ungangikholwa, ungafunda ukubuyekezwa kwe-rave yamabhayisikili e-pivot eyodwa kwabanye abahloli lapha nalapha.
Noma kunjalo, ngicabanga ukuthi ukuxhuma okuqhubekayo kuvamise ukuba ngcono ngokombono wokusebenza.Kodwa ngokushaqisa okulungile, ama-pivots angawodwa asebenza ngokufanayo kithi esingebona oshampeni abahlaselayo, nokushintshashintsha okuthwala kalula kuwenza abe yinketho enengqondo kulabo abagibelayo. odakeni oluningi.
Kunezindlela eziningi eziyinkimbinkimbi zokuzama ukukhulisa ukusebenza kahle kokumiswa: izixhumanisi eziwubukhazikhazi, izinto ezimunca ukushaqeka ezibizayo, ama-idlers.Kodwa kunendlela eyodwa kuphela eqinisekile yokusiza ibhayisikili lishelelezi: linikeze uhambo lokumiswa okwengeziwe.
Ukwengeza uhambo akwengezi isisindo, izindleko, noma inkimbinkimbi, kodwa kushintsha kakhulu indlela ibhayisikili elikubamba ngayo ukushaqeka. Nakuba kungeyena wonke umuntu ofuna ukugibela kahle, ungakwazi ukugibela ibhayisikili lakho eliyintandokazi lebanga elide ngokunciphisa ukuntenga, usebenzisa izikhiya. , noma ukwengeza izikhala zevolumu, kodwa awukwazi ukuhamba nawe njengebhayisikili elithambile elihamba kancane Njengo, ngaphandle kwalokho liyaphuma.
Angisho ukuthi wonke umuntu kufanele agibele ibhayisikili elehlayo, kodwa ukunikeza ibhayisikili elingcolile uhambo olungaphezulu kuka-10mm kungase kube lula futhi kusebenze kangcono ekuthuthukiseni ukulandelelwa, ukubamba, nokunethezeka kunomklamo wokumiswa oyinkimbinkimbi.
Ngokufanayo, kunezindlela eziningi eziyinkimbinkimbi zokuthuthukisa ukusebenza kwamabhuleki, njengama-rotor angena umoya, ama-rotor anezicucu ezimbili, ama-brake pads afakwe ama-lever, nama-lever cams.Iningi lalokhu lengeza izindleko futhi ngezinye izikhathi izinkinga. noma ukuntenga ohlelweni lwe-hydraulic.
Ngokuphambene, ama-rotor amakhulu athuthukisa amandla, ukupholisa nokuvumelana ngaphandle kokwengeza ubunzima.Uma kuqhathaniswa nama-rotor angu-200mm, ama-rotor angu-220mm azokwandisa amandla cishe ngo-10% kuyilapho ehlinzeka indawo engaphezulu ukuze akhiphe ukushisa.Ngokuqinisekile, anzima kakhulu, kodwa esimweni. ama-rotor, ama-discs anesisindo esingamagremu angu-25 kuphela, futhi isisindo esengeziwe sisiza ukumunca ukushisa ngesikhathi sokubhuleka okukhulu.Ukuze wenze izinto zibe lula, ungazama ama-rotor angu-220mm namabhuleki amabhodwe amabili esikhundleni sama-rotor angu-200mm namabhuleki angamabhodwe amane;amabhuleki angama-piston amabili kulula ukuwagcina futhi kufanele aqhathaniswe ngesisindo namandla.
Angifuni ukunikeza umbono we-Luddite.Ngithanda ubuchwepheshe obenza ibhayisikili lisebenze kangcono, ngisho noma liyingxenye encane.Ngingumlandeli omkhulu wokuthunyelwe okudonsa isikhathi eside, amakhasethi anesivinini esingu-12, isondo ukufaka, neziphethu zomoya ezinamandla amakhulu ngoba zinikeza izinzuzo ezibonakalayo.Kodwa lapho idizayini enezingxenye ezimbalwa isebenza kahle emhlabeni wangempela, ngingathanda ukuhamba ngendlela elula njalo.Akukona nje ukonga amagremu ambalwa. noma imizuzu phansi esitolo;isixazululo esilula ngokwanelisayo singase sibe sihlanzekile futhi sibe nenhle kakhulu.
Bhalisa ukuze uthole izindaba zakamuva, izindaba, ukubuyekezwa kanye nezaphulelo ezikhethekile ezivela ku-Beta nemikhiqizo esisebenzisana nayo, ilethwa ebhokisini lakho lokungenayo.
