Abo bathanda ukuhlela baya kukhetha yonke imveliso esiyihlolayo. Ukuba uthenga kwikhonkco, sinokufumana ikhomishini. Sizivavanya njani izixhobo.
Ingongoma ephambili: Nangona iCannondale Topstone Carbon Lefty 3 inamavili amancinci, amatayara atyebileyo kunye ne-full suspension, yibhayisekile ekhawulezayo nephilayo ngendlela emangalisayo emhlabeni nasezindleleni.
Nangona amatayara angama-47mm ububanzi kumavili angama-650b kunye ne-suspension engama-30mm kumavili angaphambili nangasemva, le bhayisekile inamandla isabonisa ubuchule kunye nokuqaqamba endleleni nasemhlabathini. Ixhotyiswe ngeefolokhwe zeLefty Oliver kwaye inefreyimu efanayo nezinye iibhayisekile zeTopstone Carbon kolu luhlu. Imoto ithengisa i-suspension emva kokuthengiswa ngaphandle kobunzima kunye nokungcangcazela kunye nokudibanisa. I-pivot ye-axis ezine kwityhubhu yesihlalo yenza umva wonke wefreyimu (i-brace yangasemva, ityhubhu yesihlalo, kunye nomva wetyhubhu ephezulu) ugobe njengoluhlu lwee-springs zamagqabi ezidibeneyo, zibonelela ngentuthuzelo kwindawo eyomeleleyo yokugcina inqwelo-mafutha. ​ Isondo kunye nokubambelela ngelixa igcina ukusebenza kakuhle kwe-pedaling.
USam Ebert weqela lemveliso yaseCannondale uthe uyilo lwe-single-pivot luphuculo lokuthobela imithetho, oluye lwenziwa kwezinye iifreyimu zeCannondale. Olu hlobo lokumiswa ludumile kwiibhayisekile zasezintabeni kwiihambo ezimfutshane, kwaye iibhayisekile zasezintabeni ezihlala ixesha elide neziqinileyo ziye zathobela imithetho ngendlela enokulinganiswa kwindawo yonxantathu ongasemva kangangeminyaka eliqela. Nangona kunjalo, xa iTopstone Carbon yaqaliswa ehlotyeni lowama-2019, yayilixesha lokuqala sibona ezi ngcamango zimbini zidityanisiwe.
Kukho umahluko obalulekileyo. Ngokwesiqhelo, uhambo lulinganiswa kumavili angasemva. Kwifreyimu yeTopstone Carbon (kunye neLefty), yi-25% kuphela yokuhamba okwenzeka kwi-axle. Okuseleyo kulinganiswa kwisihlalo. Nangona kunjalo, ngenxa yokuba ubungakanani ngabunye busebenzisa imo yetyhubhu eyahlukileyo kancinci kunye ne-carbon fiber laminate ukufezekisa umgangatho ofanayo wokuqhuba, ukubetheka okuchanekileyo kuyahluka ngokobukhulu.
Kutheni ulinganisa ukubetheka kwesihlalo? Lo ngumlingo wolu yilo lwesakhelo. Ukumiswa kusebenza kuphela xa uhleli. Xa umi kwiipedali, ukuguquguquka okucacileyo kuvela kumatayara, kwaye zimbalwa kakhulu iigophe kwitsheyini. Oku kuthetha ukuba xa ukhawuleza ukusuka kwisihlalo, uhambo luvakala lusebenza kakhulu kwaye lusebenza kakuhle, ngelixa ukuhlala phantsi kuvakala kukhululekile kwaye kuthambile. Kunokubonelela ngokutsala okumangalisayo kwamavili angasemva kwiintaba ezinde kunye nomhlaba orhabaxa ngaphandle kokujika nokuhla ngenxa yokumiswa okuthambileyo. Nangona isakhelo sisebenza kakuhle kakhulu, iTopstone Carbon Lefty 3 isekwicala elinomdla ngakumbi lebhayisekile yegrabile. Ukuba ufuna ibhayisekile ekhawulezayo, ke iTopstone Carbon yimveliso yayo ekhawulezayo nejolise kumdyarho, esebenzisa amavili angama-700c kunye neefolokhwe zangaphambili eziqinileyo.
Nangona uphawu olungaphandle kwendlela luyamangalisa, alunazo izixhobo ezaneleyo zokongeza izixhobo, nto leyo eyenza ukuba lungafaneleki kangako kwiihambo zeentsuku ezininzi kunezinye iibhayisekile endizikhweleyo. I-eyelet bracket yeSalsa Warroad igqunywe zizo zonke izixhobo onokuzidinga, ngelixa iTopstone Carbon Lefty 3 inokuthwala kuphela iibhotile zamanzi ezintathu kwifreyimu kunye nebhegi yetyhubhu ephezulu. Unxantathu ongasemva uza kusebenzisa izithinteli zodaka, kodwa hayi iifreyimu zepani. Nangona kunjalo, iyahambelana nekholamu yedropper enentambo yangaphakathi ye-27.2mm.
Ukuya kuthi ga kwinqanaba elithile, oku kunciphisa ukusetyenziswa kwale bhayisekile kwiindlela zosuku olunye kunye nohambo olulula lwebhayisekile. Kodwa kweli candelo, le bhayisekile inokuguquguquka okumangalisayo ngenxa yokukwazi kwayo ukujika phakathi kwendlela yokuhamba ngeenyawo kunye nothuli.
