Kedu ihe ị na-eme mgbe ụlọ ọrụ igwe anaghị arụ ọrụ na-egbo mkpa gị?Ọ bụrụ na ị bụ onye injinia imewe na ọkachamara pneumatic Paul Townsend, ị ga-arụpụta ngwaahịa nke gị wee zuo akụkụ sitere na ụdị asọmpi.
Paul kwuru banyere ọrụ nke teknụzụ okporo ụzọ nwụrụ anwụ (ya na brek hydraulic rim) na foto SRAM-Shimano hacker pụrụ iche, anyị ga-amụtakwu.
Dị ka mmalite nke afọ 2016, ahịa otu ụzọ ahụ dị nnọọ iche ugbu a.Shimano amalitebeghị ya Dura-Ace R9170 disc na Di2 combo kit (abụghị usoro R875 joysticks na breeki dakọtara bụ naanị nhọrọ hydraulic / Di2), yana SRAM's Red eTap HRD ka dị ọnwa.
Paul chọrọ iji breek hydraulic rim na igwe kwụ otu ebe n'okporo ụzọ ya, mana afọ ojuju Magura breeki calipers enweghị afọ ojuju.
Lever SRAM nwere breeki hydraulic rim nwere ọtụtụ mbelata.Ọ bụ onye ofufe Shimano Di2 gearbox, yabụ o kpebiri ijikọta ha abụọ ka ọ bụrụ mashup pụrụ iche.
Nke a gụnyere ịkwaga lever breeki na mgbakọ bọtịnụ mgbanwe yana ngwa eletrọnịkị metụtara ya site na set nke Di2 joysticks gaa na ahụ SRAM hydraulic road joystick.
Sistemụ hydraulic SRAM ka agbanwebeghị, mana ọ na-arụ ya site na eriri lever Shimano, na ngbanwe gia dabere na Di2.
Ajụrụ m Pọl ajụjụ ụfọdụ ka m mụtakwuo banyere nhazi ya pụrụ iche: ka o si arụ ọrụ, nzụlite injinịa ya, na ihe na-esote.Edeziwo azịza Pọl ogologo na idoanya.
Tupu ịga n'ihu, anyị kwesịrị ịkọwapụta na ịmegharị sistemu breeki gị n'ụzọ ọ bụla nwere ike imerụ ahụ nke ukwuu, anyị anaghị akwado ka ịme nke a.Mgbanwe na akụrụngwa ga-emebikarị akwụkwọ ikike onye nrụpụta.
Kemgbe 1980s, m na-agba ịnyịnya ígwè mgbe m na-agụ maka injinia na Mahadum Coventry Poly.N'oge ahụ enwere m Topanga Sidewinder na igwe kwụ otu ebe ugwu Mick Ives.
Arụla m ọrụ n'ichepụta igwe kwụ otu ebe na ntọala omenala, ma bụrụkwa onye injinia imewe na ọkachamara pneumatic ruo ogologo oge.M gbanweekwara ụgbọ ala na ígwè ọtụtụ afọ.
Enwere m Canyon Ultimate na 2013 ma na-enwe mmasị na teknụzụ mgbe niile, yabụ na mbụ m jiri otu eriri mpụga Shimano Ultegra 6770 Di2 kwado ya.
Mgbe ahụ, m kwalitere brek wee gbalịa Magura RT6 hydraulic rim brakes.N'ikwu eziokwu, ọ na-enye nsogbu, ma ọ na-esiri ike ịwụnye na ịwụnye.
Emeela m ọgba tum tum m n'okporo ụzọ ma tinye breeki diski Formula RR clone na ya na mgbanwe Di2.Ọ na-arụ ọrụ nke ọma, mana n'ihe dị ka oge a, ọnụahịa SRAM HydroR hydraulic rim brakes na levers na Planet-X dị ala nke ukwuu.
Mgbe m gụchara ka akụrụngwa SRAM si ejikọta ọnụ na ịmara oghere achọrọ maka modul Di2, azụrụ m breeki HydroR rim maka £100.E mesịa, azụtara m m set anọ ọzọ, onye mụ na ya so na otu onye bi na United States.
N’oge gara aga, ana m arụkwa ọgba tum tum m n’okporo ụzọ brek na wiil na Gravity Research Pipe Dream, wee mee mashups maka ịnyịnya ígwè ndị ọzọ.
Ya mere, echiche anyị bụ: breeki diski hydraulic nwere mmetụ bara ụba na obere ihe.Maguras na-egbu mgbu na ihe ihere, yabụ ọ bụrụ na achọrọ m ịkwado igwe kwụ otu ebe na brek hydraulic rim, enwere m ike ịhọrọ SRAM, mana Di2 masịrị m.
Kedu ka o siri sie ike ijikọta abụọ ahụ?Mgbe o wepụsịrị usoro mgbanwe ọsọ ọsọ, enwere nnukwu oghere na ahụ mkpanaka SRAM, ya mere azịza ya bụ: ọ dị mfe.
Azụtara m ụfọdụ levers 6770 Di2 nwere aka nke abụọ.N'ihi na 11-speed Ultegra 6870 Di2 bụ ngwaahịa ọhụrụ, ọtụtụ ndị na-ezighị ezi rere 6770 gear lever iji kwalite [njehie n'ihi na 6770 nwere ike iji ya na 6870 derailleur].Echere m na azụrụ m otu ụzọ leverage maka ihe dịka £50.
Ntọlite m na-eji oghere pivot dị na igwe breeki Di2, ma na-akwanye akụkụ igwe na plastik ngwa ngwa prototyping (3D ebipụtara) nke mbụ breeki Di2 n'elu breeki master cylinder, yabụ ike nhazi agaghị adị elu.otu ajụjụ.
M na-ebipụ ngafe akụkụ n'elu nke 6770 Di2 aka, hazie ya mechanically, wee glued ya sintered ngwa ngwa prototyping nylon akụkụ.
Emegharịrị m oghere ahụ iji mee ka oghere ahụ dị larịị na nha kwesịrị ekwesị.Na obere agba, ma ọ bụ Shimano isi awọ-acha akwụkwọ ndụ ntu na nke a, m dị njikere ikpokọta ihe niile.

A na-agbakwunye isi iyi nloghachi conical na brake master cylinder shaft iji nye ike nloghachi maka lever.
Mgbe nke ahụ gachara, naanị otu mgbanwe m mere bụ ịgbakwunye obere mgbanaka O-n'obere obe na oghere E-mpịachi ochie nke pivot pin ka ọ ghara igbochi agụba breeki ka ọ ghara ịfetụ ntakịrị.
Igwe Di2 na-agbatị n'ime oghere dị n'akụkụ ala nke isi plastik 3D e biri ebi nke breeki lever, ya mere a na-edozi ya ma ọ gaghị arapara ma ọ bụ eyi.
Mgbe ewepụchara usoro ntụgharị niile, naanị ụzọ ị ga-esi gbanwee akụkụ SRAM bụ ịdekọ grooves iji tinye eriri Di2.A na-edozi modul Di2 na mpempe ụfụfụ na oghere dị n'azụ.
