A Safer Quill Stem

One thing I’ve learned while restoring my Peugeot bicycle is that the cast alloy stems used on many of the bicycles of that era are prone to catastrophic failure. In fact, they have the nickname “death stems”! With that in mind, I ordered a modern quill stem to replace my old one.

The old stem has a 22 mm diameter, but modern bicycles are 22.2 mm diameter so the new stem requires a little modification to make it work. Basically, you have to shave off that .2 mm using sandpaper or a file. I opted to use the file to quickly take off the extra width, then sandpaper to clean it up a bit.

Before putting the stem in the fork, I put a light coat of marine grease on it to prevent corrosion and make it easier to remove later.

The new stem has a handlebar clamp that will accommodate the common 25.4 mm handlebar size but my old handlebars are about 23 mm, so I thought about buying some new handlebars. For now, I will try these shims to fit the original bars to the new stem. I might buy wider bars in the future, but I’d also like to keep Sophie as close to original as possible.

Another advantage of the new stem is that it is a bit longer and I can position the handlebars a little higher making for a slightly more upright riding position.

I’m excited to ride with the new set up (as soon as the shims arrive)! It will be nice to be able to ride in the drops without the nagging thought of the stem breaking and crashing the bike.

And soon I’ll be adding new bar tape and brake lever hoods. Sophie is looking better and better! 💜
