Komabe, chifukwa kukula kulikonse kumagwiritsa ntchito mawonekedwe osiyana pang'ono a chubu ndi carbon fiber laminate kuti zikwaniritse kuyendetsa kofanana, kusuntha kolondola kumasiyana malinga ndi kukula.
Chifukwa chiyani kuyeza kugwedezeka pa mpando wa njinga? Iyi ndi matsenga a kapangidwe ka chimango ichi. Kuyimitsidwa kumagwira ntchito kokha mukakhala pansi. Mukayimirira pa ma pedal, kusinthasintha kokhako kumachokera ku matayala, ndipo pali mapini ochepa kwambiri mu unyolo. Izi zikutanthauza kuti mukathamanga kuchokera pa mpando, ulendo umakhala wotanganidwa kwambiri komanso wothandiza, pomwe kukhala pansi kumakhala komasuka komanso kosalala. Kungapereke mphamvu yodabwitsa ya mawilo akumbuyo m'mapiri otsetsereka komanso malo otsetsereka popanda kugwedezeka ndi kutsika chifukwa cha kuyimitsidwa kokongola. Ngakhale kuti chimangocho chimagwira ntchito bwino kwambiri, Topstone Carbon Lefty 3 ikadali kumapeto kwa njinga ya miyala. Ngati mukufuna njinga yothamanga, ndiye kuti Topstone Carbon ndi chinthu chake chothamanga komanso chothamanga kwambiri, chomwe chimagwiritsa ntchito mawilo a 700c ndi mafoloko akutsogolo olimba.

Chophimba cha maso cha Salsa Warroad chili ndi zida zonse zomwe mungafune, pomwe Topstone Carbon Lefty 3 imatha kunyamula mabotolo atatu amadzi pa chimango ndi thumba la chubu chapamwamba. Katatu kakumbuyo kadzagwiritsa ntchito zoteteza matope, koma osati mafelemu a pan. Komabe, imagwirizana ndi chotsitsa chokhala ndi mawaya amkati a 27.2mm.
Pamlingo wina, izi zimapangitsa kuti njinga iyi igwiritsidwe ntchito kwambiri pa maulendo a tsiku limodzi komanso maulendo a njinga zopepuka. Koma m'munda uwu, njinga iyi ili ndi luso losiyanasiyana chifukwa imatha kusintha pakati pa misewu ndi fumbi.
