Aaron Barcheck tsuas yog 33 tab sis twb tau tsim ntau txhiab tus ncej. Tus txiv neej tom qab Mosaic Cycles tham peb los ntawm nws tus neeg sib tw ncaws pob
Muaj ntau txoj hauv kev rau hauv kev tsim. Qee tus neeg tawm haujlwm hauv Lub Nroog thiab teeb tsa hauv lawv lub tsev. Lwm tus tuaj ntawm nws los ntawm cov chav kawm engineering, qib kev kos duab zoo lossis cov kev sib txuas ntawm kev saib xyuas dav hlau.
Qee tus tsuas yog ua thaum lub sijhawm so thiab nws hloov tawm tias lawv zoo dua rau nws. Aaron Barcheck tsis yog ib qho ntawm cov no.
'Kuv tau nkag mus rau hauv kev tsim qauv ncaj qha tawm ntawm tsev kawm theem siab,' hais tias Colorado-based builder.
'Kuv tau mus rau United Bicycle Institute [UBI], tsim kuv thawj tus ncej, tau ua haujlwm ntawm Dean Titanium Tsheb kauj vab hauv Boulder ncaj qha tom qab, ua haujlwm nyob rau ntawd tau xya xyoo ces pib Mosaic hauv 2009.
Kuv xav tias qhov kev paub zoo li ntawd yog qhov tseem ceeb hauv kev tsim qauv. Kuv pib nyob rau hauv qab, ua tig ntsej muag, caum thiab reaming, sticking decals ntawm thav duab, thiab kuv ua hauj lwm kuv txoj kev, me ntsis los ntawm me ntsis.'
Barcheck hais qhov no nrog luag nyav yooj yim, tab sis thaum nws pib piav qhia lub titanium-tubed RT-1 no nws dhau los ua qhov tseeb nws tus cwj pwm tsis zoo uas zais tus neeg mob siab rau.
Tom qab tag nrho, nws tsis yog qhov ua tau me me ua rau TIG welded pob qij txha zoo li yog tias lawv tau raug fillet brazed.
' Ntawm Mosaic peb paub tseeb tias peb TIG vuam. Nws yog kuv qhov tshwj xeeb thiab qhov ua rau peb sib nrug ntawm lwm tus.
'Kuv paub tias lawv tau npog me ntsis los ntawm cov xim tab sis kuv tuaj yeem paub tseeb tias lawv zoo thiab du. Tsis muaj ntaub ntawv cov stack-o-dimes.'
The 'stack-o-dimes' Barcheck yog hais txog yog kaum ob ntawm cov me me sib tshooj ntawm cov hlau muab tub lim uas thaiv cov pob qij txha ntawm TIG weld. Qhov smoother thiab ntau dua cov puddles, tus kws tshaj lij welder raug suav tias yog.
Qhov chaw pom tseeb tshaj plaws uas tib neeg nrhiav pov thawj, nws hais tias, yog ntawm lub taub hau raj thiab lub tog raj lub tog raj, tab sis qhov kev ua kom pom zoo tshaj plaws ntawm tus kws tsim cov txuj ci yog pom nyob rau hauv qab pawg bracket, qhov twg cov ces kaum yog mob thiab cov qhov chaw ua haujlwm tsawg heev.
Ntawm RT-1 thaj chaw no yog ze rau qhov zoo tshaj plaws, yog li nws tsis muaj qhov xav tsis thoob tias Barcheck muaj qhov khoom plig rau nws lub npe suav nrog Gravel Bike Zoo Tshaj Plaws ntawm xyoo no North American Handmade Bicycle Show. Nws yog me ntsis haum rau nws thawj creation.
'Ub tus ncej ntawd yog lub tsheb kauj vab cyclocross. Kuv yeej tsis tau welded, yeej tsis machined, thiab thaum kawg kuv yuav tsum tau txiav cov nyob twj ywm tawm thiab hloov lawv vim hais tias tsis muaj txaus log tsheb clearance.
'Nws tau ua tiav ntau zaus, tab sis koj yuav tsum pib qhov twg. Kuv caij nws tau ob peb xyoos thiab nws tseem zaum hauv kuv lub chaw ua haujlwm. Tam sim no thiab tom qab ntawd kuv rub nws tawm los qhia rau tib neeg seb qhov welds zoo li cas!
'Hnub kawg nws tsuas yog TIG vuam xwb thiab kuv tsuas yog muaj lub ntsej muag rau nws, tab sis yog tias koj xav tau arty txog nws, kuv twv nws zoo li sau nrog tus cwj mem. Koj yeej tsis kov daim ntawv tiag.'

Thaum nws los txog rau cov ntaub ntawv, Barcheck thawj txoj kev hlub yog titanium: 'Nws yog ib qho ntawm ntau yam khoom siv muaj. Kuv txhais tau tias, koj tuaj yeem ua lub teeb yuag, nruj heev, kev sib tw poppy tsheb kauj vab nrog nws lossis koj tuaj yeem ua raws li cov tsheb kauj vab gravel, tag nrho ntawm cov neeg caij hla hla, tsheb kauj vab.
'Koj tau txais qhov kev xav tsis txaus ntseeg thaum koj tso lub zog los ua ke nrog qhov kev xav hauv av. Nws yog qhov zoo tshaj plaws ntawm txhua lub ntiaj teb.'
Txhawm rau tsim qhov kev xav ntawd, Barcheck tau siv qhov sib xyaw ntawm qhov loj dua ob lub pob tw thiab lub ntsuas plain 3Al-2.5V leeg ntawm RT-1.
Qee lub raj tau raug tsim kom muaj lub teeb tshwj xeeb thiab tawv los ntawm kev sib txuas cov raj dav dav nrog nyias phab ntsa tuab. Nyob rau hauv no txoj kev, tag nrho cov Mosaic cov kev cai thav duab, uas RT-1 yog ib tug, yog rider-tuned.
'Yog tias koj yog tus neeg caij 65kg koj yuav tsum tau caij lub tubes sib txawv rau tus neeg caij 95kg. Qhov ntawd yuav hloov qhov hnyav ntawm tus ncej me ntsis, tab sis peb tsis tsom ntau dhau rau qhov ntawd - nws yog hais txog qhov haum thiab tus yam ntxwv. Kuv yuav noj ntau tshaj li ob peb puas grams ib hnub twg.'
Txawm li cas los xij, RT-1 tawm ntawm ib puag ncig 1.2kg ib lub thav duab (qhov loj me nyob ntawm) lub ntsiab lus no tag nrho tsim, hnav hauv Enve 2.2 lub log, kev cai pleev xim rau Pro Vibe cov khoom tiav thiab cov khoom siv kho tshuab Dura-Ace 9100, hnyav ib luj 7kg. Qhov ntawd tsis suav nrog lub twj tso kua mis, txawm li cas los xij.
'Qhov Silca yog tej zaum lub ntiaj teb lub twj tso kua mis kim tshaj plaws, tshwj xeeb tshaj yog tam sim no tau pleev xim rau. Kev lig kev cai peb tsuas yog muab cov khoom nyoos, etched titanium thav duab tab sis xyoo no peb tau txais kev pabcuam xim.
'Kuv paub tseeb tias qee tus neeg tseem xav tias kev pleev xim titanium yog qhov tsim nyog, tab sis kuv nyiam qhov sib piv ntawm cov hlau thiab cov xim, thiab lub twj tso kua mis tsuas yog haum rau peb txoj hauv kev.
'Nyob hauv pob zeb, thaj av ua rau muaj qee yam tsheb kauj vab - tsis muaj qhov tsis zoo - yog li ntawm no calliper version koj tuaj yeem yooj yim haum 28 hli log tsheb, thiab ntawm RT-1 Disc, 30mm.
'Txhua yam koj xav tau yog lub clutch ntawm mech ntawm qhov khoom no thiab koj tau txais koj tus kheej lub tsheb kauj vab sib sib zog nqus roob.
'Zoo heev. Kev tsim tsheb kauj vab tau nce zuj zus ntxiv. Cov log tsheb sib txawv thiab kev sib tw tau qhib tag nrho cov xwm txheej tshiab, zoo li pob zeb, thiab Mosaics tau hloov zuj zus mus nrog qhov ntawd.
'Koj yeej yeej yeej qhov no thiab nws tseem yuav nrog koj nyob mus ib txhis.'
