How to Convert Your Mountain Bike to a 1x Drivetrain | Giant Rincon Restomod

🚴‍♂️ Converting a 90s MTB from 3x to 1x! Cleaner, simpler, easier to shift — this drivetrain upgrade completely transforms my Giant Rincon commuter build. In this video, I walk through every step of the 3x to 1x conversion: swapping cranks, upgrading the rear wheel, installing a MicroSHIFT 9-speed groupset, and dialing in silky-smooth shifting. Whether you're rebuilding an old mountain bike or just want fewer gears and better performance, this is a budget-friendly 1x conversion you can do at home! 🛠️ Parts & Components Used: 🚴‍♂️• MicroSHIFT 9-Speed Advent Derailleur on Amazon 👉 https://amzn.to/448kJc7 💪• MicroSHIFT 9-Speed Advent Shifter on Amazon 👉 https://amzn.to/4izlFdz 🚴‍♂️• MicroSHIFT 9-Speed Advent 11–42T Cassette on Amazon 👉 https://amzn.to/4jWnthS 💪• DJC• Narrow Wide Chainring – 36T Purple – https://amzn.to/3Ex2svp 🚴‍♂️• KMC 9-Speed Chain – 114 Links – https://amzn.to/3Ynf8LU 💪• RockBros Flat Pedals – Grippy, lightweight & tough – https://amzn.to/4k0S26j 🚴‍♂️• Wheel Master 26” Rear Wheel with Freehub – https://amzn.to/4lVs7i1 💪• Crank Arm Set 104 BCD Square Taper - https://amzn.to/44NF9b6 🚴‍♂️• Matching Front Wheel – for that clean, upgraded look 💪• Purple Compressionless Cable Housing – for a clean shift feel 🔧 Tools I Used: 😎 Hex Wrench Set 😎 Pedal Wrench 😎 Crank Puller with 14mm Socket 😎 Shimano Cassette Socket 😎 Hozan Lock Ring Wrench 😎 Bottom Bracket Removal Tool 😎 Big Adjustable Wrench 😎 Chain Pliers + Chain Breaker (optional) 😎 Park Tool DAG-2.2 Derailleur Hanger Alignment Tool 😎 Park Tool Polylube 1000 😎 Cable & Housing Cutter 😎 Phillips Screwdriver + Flathead 😎 15mm Wrench 📺 WATCH NEXT: This video is part of my Giant Rincon RestoMod – a trash-picked MTB turned budget commuter.
