FULL REBUILD Shimano 105 STI 8s Brifter ST-1055

Shimano STI combined brake + shift levers tend to gum up with age and stop working. They are of high quality and can usually be disassembled completely. After a thorough cleaning and reassemble their proper function can be restored.
This clip shows a complete disassembly and reassembly of a right hand 8 speed Shimano 105 (ST-1055) STI shifter with close details. Left hand shifter is rebuilt here: • FULL REBUILD Shimano 1...
The process is complicated and recommended to experienced people. I'm not responsible for damaged parts.
I made a mistake at 37:32 min: The main pin should be installed the other way around.
Thank you for watching! Leave wishes for further instruction clips in the comments.

    Thank you! The snag I hit was on the release lever spring. It wraps around a bushing, but I was letting it jump above the bushing while setting its tension. Also, it was easy to fab a tool for the four-notch mech locking nut out of brass tubing, making it easy to trial fit the mech.

    Bravo pour cette super vidéo, j'ai pu réparer quelques leviers défectueux grâce a vous (y), par contre a la fin de la vidéo j'ai l'impression que vous remettez l'axe du levier dans le mauvais sens ;)

    Bravo, le Vélomec : beau travail. Il y avait des étapes et des détails que je n'avais pas pu voir correctement, sur d'autres vidéos concernant le démontage et le remontage des ST-1055. Là, et avec beaucoup de patience, tout fonctionne ! Quinze mois que j'attendais ça... Merci , merci beaucoup ! Une question : j'ai l'impression que je ne peux utiliser que sept couronnes sur les huit. Qu'est-ce que j'ai pu louper ?

    Hi love the video-using it to re-build a lever as I watch-- keep getting stuck though- cant work out were the spring ends, in between the plates go/ butt against at approx 22 to 24 mins , can you help please?

    Seen from above: The shorter angled link of the spring clicks into the upwards bent ear from the lower plate. The longer angled link of the spring, going counterclock wise from the smaller one, clicks into the downwards bent ear from the upper plate. Watch very closely in high resolution, it's hard to describe

    Good work, do you know if u can adjust the lever clearance to the bar? To reach the levers easier. Like for smaller hands for example. Cheers

    Thanks. To my knowledge this is not possible. Maybe try other bars or add a spacer where the lever is stopped in the housing

    @@levelomec yes.. Putting a shim/spacer in between was one of the solutions i was thinking about. But i think about some modern compatible levers. U maybe know of some modern and compatible 8 gear levers that could easily replace the old ones here and have a better shape and adjustment points? Cheers

    Hey! Just found your video!! Im restoring an old vitus 979 with a shimano 105 groupset. The groupset is ok but both brifters are not working. Probably because its been 25 years out of office. Do you have any recomendation? I was thinking about using a degreaser before disassembly and hope it is just old grease, or just disassembly like you. Thanks in advance Ooh it is the same model as yours but 2x8. St1055

    In my experience it's usually old grease that blocks the mechanism. You can try to soak it in degreaser for some time. maybe it works, otherwise take it apart 🤞
