Upgrade Vintage 10 Speed Bike To 14 Speed & Indexed Shifting

I show how to update a vintage 10 speed bike (Raleigh Grand Prix) to 14 speeds with Shimano SIS indexed shifting. I spread the chain stays to accommodate a wider wheel. The 5 speed hub rear wheel is replaced with another 27“ wheel with a 6/7 speed hub and 7 spd freewheel. I also replace the rear derailleur, chain. And the Huret friction shifters were replaced with Shimano indexed shifters. If I wanted to put the money into it, I could have easily spread the chain stays to 130mm, and upgraded the bike with an 8/9/10 speed hub wheel. But that would have meant going to 700c wheels. And the whole thing would have cost more. ▶ SUBSCRIBE & HIT THE 🔔 👍 And please give my video a thumbs up 👍 ▶ ▶TOOLS ▶SHIRTS ▶WEBPAGE
