Kusintha Kwamagetsi Kwapanjinga Iliyonse

Shimano, Campagnolo ndi SRAM onse akhala akusintha zamagetsi kwazaka zingapo, FSA yawajoina, ndipo SRAM yasintha makina ake a eTap kukhala 12-liwiro ndikuyambitsa Force eTap yotsika mtengo. Ndi mabasiketi athunthu osinthira amagetsi omwe amawononga pafupifupi $ 2,400, kodi mukuganiza kuti musamuka?

Kusintha kosintha
Kodi ndizolondola kwambiri kuposa momwe kusintha kwamagetsi kumakhalira? Ndi makina, ngati mukukankhira lever kuti asunthire kuchokera pa njinga imodzi kupita ku ina mech yakutsogolo imachitanso chimodzimodzi nthawi zonse. Ndi makina amagetsi mech yakutsogolo imachita mosiyana pang'ono kutengera ndi sprocket yomwe mudalipo panthawiyo.

Tengani dongosolo la SRAM's eTap. Mukachoka panjinga yaying'ono kupita pa njinga yayikulu, khola limasunthira pang'ono kuti lithandizire unyolo kulumpha. Kenako kamphindi kakang'ono kamphindi pambuyo pake, chingwecho chikakhala pamwamba apo, khola limabwereranso mkatimo momwe limakhalira.

WNkhuku yomwe mukusunthira kuchoka pa njinga yayikulu kupita ku tcheni tating'onoting'ono, khola limasunthira mkatimo magawo awiri. Choyamba, chimasinthana mokwanira kusunthira unyolo pansi. Kenako chidutswa chachiwiri pambuyo pake, unyolo ukakhala pansi pa mphete yamkati, imasunthira patsogolo pang'ono. Kuchita zinthu motere kumapewa kuthekera koti unyolo ubwerere mkati mwa njinga yamagetsi.

Momwe zinthu ziwirizi zimachitikira zimadalira sprocket yemwe muli panthawiyo. Nenani kuti muli ndi tcheni panjinga yaying'ono yaying'ono ndi imodzi mwazitsulo zazikuluzikulu ndipo mukufuna kusintha unyolo waukulu. Mech yakumbuyo imapangitsa mech yakutsogolo kudziwa kuti imafunikira kupitilira kuposa momwe zingakhalire ngati unyolowo ungatulukire panja pa tina tating'ono tating'ono.

Chofunika ndikuti mumasintha kwambiri ngakhale mutanyamula katundu.

"Dura-Ace kapena Ultegra Di2 kusuntha zida zamagetsi kumayendetsa unyolo ndendende pomwe umafunikira kudzera poyikapo kutsogolo kapena kumbuyo kwa derailleur," atero a Shimano.

“Sayansi yomwe ili kumbuyo kwake ndiyodabwitsadi ndipo imatha kusinthidwa momwe mungasinthire zinthu [onani pansipa]. Mumapanga lamulo ndipo dongosololi limayankha molondola nthawi iliyonse. Pa mpikisano, kudalirika komanso chidaliro chomwe chimapereka kumatha kusiyanitsa pakati pakupuma kapena ayi. ”

Kusintha mwachangu
Ngati mukufuna kusuntha pa kaseti ndi makina osinthira, muyenera kukanikiza lever kangapo (makina osiyanasiyana amafunika makina osindikizira osiyanasiyana). Ndi makina amagetsi mutha kusunthira mbali imodzi ya kaseti kupita mbali inayo mukasindikiza ndikugwira lever. Ndikosavuta pang'ono.

Campagnolo akuti, "[EPS kumbuyo derailleur] nthawi zosinthira tsopano ndi 25% mwachangu kuposa zomwe zimayendera kumbuyo derailleur (kutenga masekondi 0.352 kuti musinthanitse ma sprocket)".

Mutha kusintha kusintha kwanu
Ndi Shimano Di2 mutha kusintha liwiro losunthika ndipo kuchuluka kwa magiya omwe makinawo amasunthira mukasindikiza ndi kugwira lever. Muthanso kusinthana magwiridwe antchito a lever wokweza ndi wotsikira pansi, ngakhale ntchito za lever wamanzere ndi lever woyenera. Makina oyamba a Red eTap a SRAM sanathe kusintha kusintha, koma magulu awiri atsopano a AXS 12-othamanga akhoza kusinthidwa kudzera pulogalamu ya smartphone.

Palibe chovala cha unyolo
Kamodzi ka Shimano Di2 kapena Campagnolo EPS ikakhazikitsidwa molondola, ziribe kanthu momwe muliri simufunikanso kusintha mawonekedwe a mech yakutsogolo kuti muteteze unyolo wopaka pamapale ammbali am'mbali chifukwa amangochitika zokha.

Mukasinthira derailleur lakumbuyo nthawi zina mumamva phokoso pomwe mech yakutsogolo imasunthira pang'ono kuti izindikire malo atsopanowo, lingaliro ndikukonza bwino ndikuchepetsa kuvala.

SRAM imati izi sizofunikira ndi dongosolo lake la eTap chifukwa palibe chiwopsezo cha unyolo ngakhale mutagwiritsa ntchito ma chain / sprocket combo.

Ntchito yosavuta
Kusintha zida zamagetsi pamagetsi kumafunikira mayendedwe ofupikira kwambiri kuposa ofanana ndi makina. Mukungokanikiza batani, osafunikira kuti musese chopingasa.
Kusuntha ma levers pamakina sikungakhale kovuta kwambiri padziko lapansi, koma kungakhale kovuta ngati mukufuna kusuntha pamitundu yonse yomwe mungapeze. Zinthu ndizosavuta pang'ono ndi makina amagetsi.

Ndi SRAM's eTap system lever pa shifter imodzi imachita upshifts, lever pa shifter ina imachita downshifts, ndipo mumawakankhira onse awiri nthawi yomweyo kuti asinthe pakati pa ma chainrings. Ndi njira yosavuta kugwiritsa ntchito, ngakhale mutavala magolovesi akuluakulu kapena timbewu tating'onoting'ono nyengo yozizira.

Zosankha zingapo zosintha
Panjinga yamsewu ndi Shimano kapena SRAM kusunthira kwamagetsi nthawi zambiri mumasintha magiya kudzera pa mabuleki ophatikizika ndi zida zamagalimoto, monga momwe mungachitire ndi makina, koma mutha kuwonjezera ma satellite osunthira kwina pagawo lanu kuti musavutike kusintha zida nthawi zina, makamaka mukamathamanga.

Pogwiritsa ntchito zamagetsi, mutha kukhala ndi ma shifter pazowonjezera za aero komanso pamunsi pa bar, kotero ndizosavuta kusintha zida ngati mutatuluka pachishalo mukakwera kapena mutuluka pakona yolimba.

Ndi makina amagetsi mulibe kachitidwe kakang'ono kosamalira ndipo simusowa kuti musinthe chingwe. Kukonzekera pang'ono, ngati kulipo, kumafunika pakukhazikitsa koyamba.

Ngakhale makonzedwe oyambawo ndiosavuta ndi makina a SRAM's eTap. Ndi opanda zingwe kotero palibe chifukwa chotsitsira zingwe kudzera mufelemu yanu.

Makina osunthira akhala akugwira ntchito kwazaka zambiri, ndipo apitiliza kutero, ndipo ndiotsika mtengo kwambiri kuposa kukhazikitsidwa kwamagetsi. Ngati simukupeza maubwino omwe tawatchula pamwambapa akukakamizani kuti musinthe kukhala amagetsi, palibe wopanga zinthu zomwe asiya kusintha kosintha nthawi iliyonse posachedwa.

Chimodzi mwazinthu zomwe amatsutsa pafupipafupi zamagetsi ndizotheka kutuluka pakatikati paulendo. Izi ndizokayikitsa kuti zingachitike pokhapokha ngati simungayike chidwi. Mukhala ndimakilomita mahandiredi angapo pakati pa zolipiritsa pamakina aliwonse osinthira zamagetsi, komanso chenjezo lambiri kuti muli ndi madzi ochepa.

Ngakhale batiri litakhala lathyathyathya, mutha kuyika unyolo m'miyendo yomwe mukufuna ndikukwera pawokha.

Zachidziwikire, simuyenera kusintha kosinthira kwamagetsi.

"Muthanso kusunthira molondola, mwachangu komanso molondola kuchokera ku Dura-Ace, Ultegra kapena zida zamagalimoto 105," akutero Shimano. "Mwakutero, komanso kupanga lamulo - mwachitsanzo kukankha lever - mumagwiritsanso ntchito makinawo pokoka kapena kumasula chingwe.

“Pali luso linalake lokhazikitsa njira yanu yoyendetsera galimoto mwanjira imeneyi. Oyendetsa ambiri amakonda kudziwa momwe angagwiritsire ntchito chinthu chilichonse mkati mwa ma drivetrain awo, omwe ndiosavuta ndimakina.

"Ndi mtundu uliwonse wosunthira wokhala ndi zabwino zake, funso ndilakuti ngati mukufuna kuyendetsa sitima yanu yoyendetsa podina batani, kapena kuyigwiritsa ntchito pogwiritsa ntchito lever. Mwina yankho ndikuti mukhale nazo zonse kutengera mtundu waulendo wanu. ”

Anthu ambiri omwe timawadziwa omwe ayesa kusuntha kwamagetsi kwakanthawi kwakanthawi amafuna kumamatira, koma chisankho ndi chanu.
