Labo abathanda ukuhlela bazokhetha yonke imikhiqizo esiyibuyekezayo.Uma uthenga kusixhumanisi, singase sizuze ikhomishini.Siwahlola kanjani amagiya.
Iphuzu eliyisihluthulelo: Nakuba i-Cannondale Topstone Carbon Lefty 3 inamasondo amancane, amathayi anamafutha kanye nokulengiswa okugcwele, iyibhayisikili elishesha ngokumangalisayo futhi eliphilayo ebhuqwini nasemigwaqweni.
Ngaphandle kwamasondo angu-47mm ububanzi emasondweni angu-650b kanye ne-suspension engu-30mm emasondweni angaphambili nangemuva, leli bhayisikili eliyi-burly lisakhombisa ukushesha nokugqama emgwaqeni nothuli.Ifakwe izimfoloko ze-Lefty Oliver futhi inohlaka olufanayo namanye amabhayisikili e-Topstone Carbon ochungechungeni.Imoto idayisa ukumiswa ngemuva kokudayiswa ngaphandle kobunzima besisindo nokudlidliza nokuxhumana.I-pivot ye-four-axis kushubhu yesihlalo yenza yonke ingemuva lohlaka (i-brace yangemuva, ishubhu lesihlalo, ngisho nengemuva leshubhu eliphezulu) agobe njengochungechunge lweziphethu zamaqabunga axhunyiwe, linikeza induduzo endaweni ebambayo emagebhugebhu​ Ucansi kanye nokudonsa ngenkathi kugcinwa ukusebenza kahle kwe-pedaling.
U-Sam Ebert wethimba lomkhiqizo wase-Cannondale uthe umklamo wephivothi eyodwa uwukuthuthukisa ukuthobela imithetho, oklanywe kwaba ezinye izinhlaka ze-Cannondale.Lolu hlobo lokumiswa ludumile kumabhayisikili asezintabeni ohambweni olufushane, futhi amabhayisikili ahlala isikhathi eside kanye nezintaba ezinomsila oqinile abe nokuhambisana okulinganiselwe endaweni engunxantathu ongemuva iminyaka eminingana.Kodwa-ke, ngenkathi kwethulwa i-Topstone Carbon ehlobo lika-2019, bekungokokuqala ngqa sibona le mibono yomibili ihlanganiswa.
Kunomehluko obalulekile.Ngokujwayelekile, ukuhamba kukalwa ngamasondo angemuva.Kufreyimu ye-Topstone Carbon (kanye ne-Lefty), kuphela ama-25% ohambo avela ku-ekseli.Okunye kukalwa esihlalweni.Nokho, ngenxa yokuthi usayizi ngamunye usebenzisa umumo weshubhu ohluke kancane kanye ne-carbon fibre laminate ukuze uzuze ikhwalithi yokushayela efanayo, ukushaywa okunembile kuyahlukahluka ngosayizi.
Kungani ulinganisa ukushaywa kwesihlalo?Lona umlingo walo mklamo wohlaka.Ukumiswa kusebenza kuphela uma uhlezi.Uma umi kuma-pedals, okuwukuphela kokuguquguquka okusobala kuvela kumathayi, futhi kumbalwa kakhulu ukugoba kweketango.Lokhu kusho ukuthi uma usuka ngesivinini usuka esihlalweni, ukugibela kuzwakala kusebenza ngokwedlulele futhi kusebenza kahle, kuyilapho ukuhlala phansi kuzwakala kukhululekile futhi kubushelelezi.Inganikeza ukudonsa kwamasondo angemuva okumangalisayo emithambekeni yezintaba nasezindaweni ezimazombezombe ngaphandle kokugoqa futhi ukuguquguquka ngenxa yokumiswa okuwubukhazikhazi.Ngaphandle kokusebenza kahle okuphezulu kohlaka, i-Topstone Carbon Lefty 3 isesekupheleni kwebhayisikili eliwugwadule.Uma ufuna ibhayisikili elisheshayo, khona-ke i-Topstone Carbon ingumkhiqizo wayo osheshayo futhi ogxile emjahweni, esebenzisa amasondo angu-700c namafoloko angaphambili aqinile.
Nakuba uphawu olungekho emgwaqeni luhlaba umxhwele, alinazo izinto ezanele zokwengeza okokusebenza, okulenza lingafaneleki kakhulu ohambweni lwezinsuku eziningi kunamanye amabhayisikili engiwagibele.Ubakaki wamehlo we-Salsa Warroad umbozwe ngazo zonke izinto ongase uzidinge, kuyilapho i-Topstone Carbon Lefty 3 ingaphatha kuphela amabhodlela amanzi amathathu kuhlaka kanye nesikhwama seshubhu esiphezulu.Unxantathu ongemuva uzosebenzisa ama-mudguards, kodwa hhayi ama-pan frame.Nokho, iyahambisana nekholomu ye-dropper enezintambo zangaphakathi ezingu-27.2mm.
Ngokwezinga elithile, lokhu kukhawula ukusetshenziswa okuyinhloko kwaleli bhayisikili ekuvakasheni kosuku olulodwa nohambo lwebhayisikili olulula.Kodwa kulo mkhakha, leli bhayisikili linokwehlukahlukana okumangalisayo ngenxa yekhono lalo lokushintsha phakathi kwemigwaqo yaseceleni nokungcola.
