Sequenza per una revisione completa della bici da strada

20

Ho una bici da strada che prevedo di revisionare completamente presto. Nel corso degli anni, e con diverse bici, ho revisionato quasi tutti i componenti, ma non sono mai riuscito a farlo per un'intera bici, dall'inizio alla fine.

Esiste una sequenza ottimale per una revisione della bici? O importa?

È importante per te spogliarti fino a formare una cornice nuda? O la revisione di un sistema alla volta è OK?

— Jay Bazuzi,

Probabilmente non si spoglierà a nudo frame. Non sono sicuro di averne bisogno.

Non mi piace il titolo, ma non riesco a pensarne uno migliore! Buona domanda.

Di solito comincio togliendo una cornice. Lascerò i cavi accesi se non vado così lontano ma almeno smontano l'auricolare ed estraggo il BB. Una volta arrivato così lontano, finirò il telaio e poi passerò alle ruote. Estrarre i cuscinetti e controllare le sfere, ottenerne di nuove se necessario e reimballare i mozzi. A questo punto pulisco anche la cassetta poiché è quasi completamente separata.

Non ho mai avuto pedali che richiedessero una ricostruzione, ma credo che lo farei dopo aver rimesso le pedivelle.

Quindi rimettilo insieme.

Comincio con un controllo M di base: cosa c'è che non va nella bici. Elencare le cose che devono essere fatte. Ciò significa un'ispezione ravvicinata del telaio per danni / incrinature - se il telaio è una scrittura della bici è solo un donatore di parti e spogliato.

Comincio rimuovendo tutti i bit danneggiati e decido se sarebbero riparabili dopo una ricostruzione o se avessero bisogno di essere sostituiti.

Una volta che tutto è fuori dalla bici che non funziona, faccio un giudizio sul fatto che valga la pena ripararlo. Evita di sprofondare molto tempo in una bici se è marginale. Ci sono molte biciclette là fuori, e mentre il sentimentalismo e la storia aiutano a spostare il confine, devi ancora essere selettivo.

Lavorare su ciascun sottosistema a sua volta. IE renderei perfetto il BB e poi passerei alle pedivelle. Quindi ruota posteriore, cassetta, deragliatori, catena.

Pulisci sempre le cose prima di lavorarci. Una bici pulita è più piacevole con cui lavorare. Quindi fai prima le parti sporche: trasmissione, mozzi delle ruote, passaruota ecc.

Lascia i dettagli di finitura fino a dopo. Sella, barra, catadiottri, cavi interni per freni / cambi e freni sono verso la fine della sequenza.

Infine, prova la bici. Dovresti guidarlo per alcuni minuti, inizialmente lento, poi alzarti per testare i freni e il cambio.

Dopo 4-6 settimane vorrai modificare anche i cavi del freno e del cambio: si inseriscono con l'uso.
