Jim woene allegearre witte: hoe hâldt de opwurdearre fyts him?",

 "text": "Myn fyts foar nei it wurk\nLêste winter haw ik my in Sensa Cintura fyts mei de Gates CDN Carbon Drive oanskaft om it Nederlânske waar troch te kommen. Nei mar 1800KM yn acht wiken wie it tiid foar wat upgrades. Ik_moast_de_Gates_CDN_carbon_drive_upgrade,_lês_der_oer_yn_myn_berjocht_fan_ferline_jier. (https://willem.com/en/2018-02-24_creating-the-ultimate-commuter-bike/) Letter besleat ik de_ferve_fan_myn_fyts_ôf_te_heljen_foar_in_minimalistyske,_rau_aluminium_look (https://willem.com/en/2018-06-09_removing-paint-from-a-bike-frame/).\nIn jier op myn fyts (±6000KM)\nYn de ôfrûne tolve moannen haw ik dizze fyts yntinsyf brûkt. Oarspronklik wie ik fan plan dizze fyts allinnich yn de winter te brûken, mar ik fûn him sa moai dat ik him it hiele jier brûkt haw. Fan snie en iis yn de winter oant de hjitte fan de simmer.\nBannen\nYn it jier haw ik genoaten fan de Schwalbe Durano bannen, mar ik haw in soad lekke bannen hân (meast troch de protte kilometers). Do wurdst der handich yn om bannen te ferfangen, mar it bliuwt ergerlik.\nFanwegen de ekstra glêde omstannichheden haw ik oan it begjin fan dizze winter myn bannen ferfongen. Ik haw de flugge, sportive Schwalbe Durano bannen ruile foar lekbestindige Schwalbe Marathon Plus Tour rubber mei in soad grip.\nDe Schwalbe Marathon Plus Tour bannen binne echte bisten. Ik haw de ôfrûne 3000KM gjin inkelde lekke bân hân en dat fyn ik hiel, hiel moai. Sa moai sels, dat ik der oer neitink om se op myn fyts te litten (en de tas foar de reservebân en de pomp kwyt te reitsjen). Sjoch dizze_fideo (https://m.youtube.com/watch?feature=youtu.be&v=Sl4XZT_mYVc) as do twivelest oan har sterkte. Se binne swierder as de Durano's, mar net sa slim wat rydeigenskippen en fersnelling oangiet.\nGates Carbon CDN/CDX Drive\nSa, ferline_jier_liet_nei_mar_1800KM_it_orizjinele_Gates_Carbon_CDN_efterste_tandrâd_tekens_fan_serieuze_ferslijting_sjen (https://willem.com/en/2018-02-24_creating-the-ultimate-commuter-bike/). Ik wie slim teloarsteld oer dizze mindere kwaliteit en de minne kar fan Sensa foar de CDN-searje fan de Gates Carbon Drive.\nIk haw it efterste tandrâd ferfongen troch in CDX-model fan bettere kwaliteit en wie hiel benaud om te sjen oft dat op de lange termyn better wêze soe. Dat bliek sa te wêzen, it CDX efterste tandrâd is nei 6000KM noch prima. Hoera!\nDe oandriuwing prestearret konstant goed, it swakste part fan it oarspronklike CDN-systeem is it efterste tandrâd. De CDN-riem en it foarste tandrâd binne dêrfoaroer hiel bestindich.\nIt is fernuverjend hoe taai it Gates Carbon Drive systeem is, yn de winterske moannen mei snie wjerstie it omstannichheden dy't in tradisjonele ketting en derailleur maklik skeind hawwe soene. Tegearre mei de Shimano Alfine fersnellingsnaaf is er klear foar noch in soad kilometers.\nOare dingen dy't stikken gongen\nYn myn 12 moannen op de fyts hold myn efterlampe op mei wurkjen troch in elektryske defekt yn it LED-array. Myn Busch und Müller efterlampe sit yn it efterspatboerd. Dy sit fuort yn de spuit fan smoargens en wetter fan de bân. Ik tink dat dit in resept is foar útfal, de elektryske ûnderdielen soene better beskerme wurde moatte tsjin it smoarge wetter.\nAs do bist lykas ik (±85KG yn gewicht) en mei in hege snelheid fytst (>25KM/h), dan bring do de grinzen fan de struktuerele yntegriteit fan alle ûnderdielen fan dyn fyts op. Dat betsjut dat dingen stikken gean kinne as it wat rûger wurdt. Ik haw ien fan de efterste spaken brutsen doe't ik in gat yn de dyk rekke!\nMear as nei it wurk\nDe natuerlike habitat fan myn fyts is de dyk tusken myn hûs en kantoar. Mar ik haw de fyts yn it jier ek yn oare situaasjes brûkt, gewoan om't ik him sa moai fûn.\nMei in goed slot kinst de fyts brûke yn it sintrum fan Amsterdam, it herinnert dy oan hoe alsidich in fyts foar nei it wurk is. Dat is fansels in grut foardiel boppe in folbloed racefyts (dy wolst net sûnder tafersjoch litte yn de stêd...)\nKrekt as_ferline_jier (https://willem.com/en/2017-06-30_fietselfstedentocht-2017/) haw ik de 235KM Fietselfstedentocht fytst. Ik tocht dat it de ultime úthâldingsproef wêze soe as ik de Fryske tocht fan helden op myn betroubere fyts útfytse koe. Hy die it en it wie geweldich!\nKonklúzje\nIk hâld fan fytsen en myn fyts foar nei it wurk is wierskynlik de alsidichste, stevige fyts dy't ik ea hân haw. It is moai om te witten dat er yn alle omstannichheden betrouber wurket.\nMar úteinlik makket it net echt út hokker fyts do ride. Wat it measte telt, is de rit sels! Der op út te wêzen op de fyts jout in gefoel fan frijheid en rêst dat dreech te oertreffen is!\nUpdate\nBenijd hoe't it is om in racefyts mei in Gates Carbon Drive te hawwen? Lês dan myn_ferhaal_oer_Siegfried_Road (https://willem.com/en/2020-04-30_minimalistic-road-bike-with-gates-carbon-drive/).\nNei 21.000KM haw ik noch in update oer de fyts skreaun: lês_it_hjir (https://willem.com/en/2021-01-10_commuter-bike-checkup/).",
