Labo abathanda ukuhlela bazokhetha yonke imikhiqizo esiyibuyekezayo. Uma uthenga kusixhumanisi, singase sithole ikhomishini. Sizihlola kanjani izinto zokusebenza.
Iphuzu elibalulekile: Nakuba iCannondale Topstone Carbon Lefty 3 inamasondo amancane, amathayi anamafutha kanye ne-full suspension, iyibhayisikili elisheshayo nelinempilo ngendlela emangalisayo othulini nasemigwaqweni.
Naphezu kwamathayi angu-47mm ububanzi emasondweni angu-650b kanye nokumiswa okungu-30mm emasondweni angaphambili nangemuva, leli bhayisikili elinamandla lisabonisa ukushesha nokugqama emgwaqweni nasemhlabathini. Lihlonyiswe ngamafoloko e-Lefty Oliver futhi linohlaka olufanayo namanye amabhayisikili e-Topstone Carbon ochungechungeni. Imoto ithengisa ukumiswa kwangemva kokuthengiswa ngaphandle kobunzima besisindo nokudlidliza nokuxhumana. I-pivot ene-axis ezine eshubhu lesihlalo yenza lonke ingemuva lohlaka (i-brace yangemuva, ishubhu lesihlalo, ngisho nengemuva leshubhu eliphezulu) ligobe njengochungechunge lweziphethu zamaqabunga ezixhunyiwe, linikeza induduzo endaweni eqinile. Ubulili kanye nokubambelela ngenkathi kugcinwa ukusebenza kahle kokugwedla.
USam Ebert wethimba lomkhiqizo waseCannondale uthe ukwakheka kwe-single-pivot kuwukuthuthuka kokuhambisana, okuye kwaklanywa kwezinye izinhlaka zeCannondale. Lolu hlobo lokumiswa ludumile kumabhayisikili asezintabeni ohambweni olufushane, futhi amabhayisikili asezintabeni aqinile omgwaqo nawasezintabeni aqinile abe nokuhambisana okulinganiselwe endaweni kanxantathu wangemuva iminyaka eminingana. Kodwa-ke, lapho iTopstone Carbon yethulwa ehlobo lika-2019, kwakungokokuqala ngqa sibona le mibono emibili ihlanganiswa.
Kunomehluko obalulekile. Ngokuvamile, ukuhamba kukalwa ngamasondo angemuva. Kuhlaka lwe-Topstone Carbon (ne-Lefty), u-25% kuphela wokuhamba kwenzeka ku-axle. Okunye kukalwa esihlalweni. Kodwa-ke, ngenxa yokuthi usayizi ngamunye usebenzisa isimo seshubhu esihlukile kancane kanye ne-carbon fiber laminate ukuze kufezwe ikhwalithi efanayo yokushayela, ukushaywa okunembile kuyahlukahluka ngosayizi.
Kungani ulinganisa ukushaya kwesihlalo? Lona umlingo walo mklamo wohlaka. Ukumiswa kusebenza kuphela uma uhleli. Uma umi kuma-pedal, ukuguquguquka okusobala kuphela kuvela emathayini, futhi kuncane kakhulu ukugoba eketangeni. Lokhu kusho ukuthi uma usheshisa usuka esihlalweni, uhambo luzizwa lusebenza kakhulu futhi lusebenza kahle, kanti ukuhlala phansi kuzizwa kukhululekile futhi kubushelelezi. Kunganikeza ukubamba okumangalisayo kwamasondo angemuva emithambekeni yezintaba ephakeme kanye nendawo emagebhugebhu ngaphandle kokugoba nokuwa ngenxa yokumiswa okubushelelezi. Naphezu kokusebenza kahle kohlaka, i-Topstone Carbon Lefty 3 isesengxenyeni ekhangayo kakhulu yebhayisikili eliyitshe. Uma ufuna ibhayisikili elisheshayo, khona-ke i-Topstone Carbon ingumkhiqizo wayo osheshayo futhi ogxile kakhulu emjahweni, esebenzisa amasondo angu-700c namafoloko angaphambili aqinile.
Nakuba uphawu olungaphandle komgwaqo luhlaba umxhwele, alunazo izinto ezanele zokwengeza izinto, okwenza lungafaneleki kangako ohambweni lwezinsuku eziningi kunamanye amabhayisikili engike ngawagibela. I-eyelet bracket ye-Salsa Warroad imbozwe yizo zonke izinto ongase uzidinge, kuyilapho i-Topstone Carbon Lefty 3 ingathwala amabhodlela amanzi amathathu kuphela ohlakeni kanye nesikhwama seshubhu esiphezulu. Unxantathu ongemuva uzosebenzisa izivikelo zodaka, kodwa hhayi ozimele bepani. Kodwa-ke, iyahambisana nekholomu ye-dropper enezintambo zangaphakathi ezingu-27.2mm.
Ngezinga elithile, lokhu kunciphisa ukusetshenziswa kwaleli bhayisikili ezingozini zosuku olulodwa kanye nohambo lwebhayisikili olulula. Kodwa kulo mkhakha, leli bhayisikili linokuguquguquka okumangalisayo ngenxa yekhono lalo lokushintsha phakathi kwezindlela zokuhamba ngezinyawo kanye nothuli.
