Vintage racing bikes tend to be rather heavy by 21st century standards. Components are almost exclusively steel, in comparison to modern aluminum, carbon fiber and titanium parts. While you cannot lighten the frame itself without damaging it, you can replace the bike’s other components to significantly reduce its weight and increase its speed.
Step 1
Obtain a new fork. The fork is the only replaceable part of your vintage racing bike’s frame, and with the availability of carbon fiber forks, you can significantly reduce frame weight. Aluminum forks are also much lighter than steel forks, and much cheaper, if cost is a concern. Vintage Trek notes that if you wish to use the modern threadless headset system, you will definitely need a new fork designed to work with that system.
Step 2
Replace the wheels with aluminum or carbon fiber wheels in the same diameter as the original ones. Steel wheels are among the heaviest components--and the easiest to replace. Replacing steel wheels gives you improved braking power, and eliminates concern about wheel rust. If your bike used 27-inch wheels, you may be able to substitute 700c wheels, because they are almost the same size, but check this before you buy. You may need different size brakes if you change wheel diameter.
Step 3
Replace the bottom bracket, cranks and pedals. These components add significant weight to your vintage racing bike. and offer inferior performance when compared with modern components. You may need to buy a bottom bracket adapter kit, because many old bottom brackets needed a larger tube than modern bottom brackets.
Step 4
Replace the handlebars, stem and seat post. The original components offer incredible durability, but like all other steel components, they are heavy. Look for aluminum or carbon fiber replacements. When replacing the handlebars, consider also replacing the brake levers. This may not yield much weight savings, but can improve your braking performance significantly.
Tips and Warnings
- Bring your frame with you to the bike shop when you look for any component. Vintage bikes may use a variety of outdated component sizes, requiring significant attention to detail, and the knowledge of an experienced mechanic to locate the correct parts. Replacing the rear wheel of your vintage bike requires special care. Bike expert Sheldon Brown notes that vintage bikes typically used fewer gears than modern bikes, and may have narrow rear dropouts to match the narrowness of the sprocket cluster. Typically, you can adjust steel bikes to accommodate wider hubs or additional gears, while you can't do this with other types of frame material If you wish to add speeds to the rear wheel, you might need to change the gear shifter, as well.
