Vintage MTB bumpy build - FAIL & FIX - Giant GSR 400

Watch as we tackle a challenging vintage MTB restomod, converting a classic Giant GSR 400 into a sleek, minimalist single-speed city cruiser. This "fail and fix" restoration wasn't all smooth sailing; we had to overcome a crooked frame component and a last-minute brake lever swap to transform this 90s relic into a high-quality urban commuter. From a fast-paced disassembly timelapse to a relaxing ASMR silent assembly. For the builders out there: have you ever had to pivot on parts after the bike was already half-assembled?
