Can you convert a threadless headset?

The Innicycle 1″ Threaded to 1-1/8″ Threadless Conversion Headset might just be the cleanest way to make it happen. The cool thing about Innicycle’s conversion headset is that it replaces the entire threaded headset, and once installed, functions much like a modern threadless headset.

Are quill stems bad?

Condensed answer: Quill stems aren’t inherently bad and have proven themselves over the years. However, they require a heavier steerer and a more finicky headset. They also limit the number of forks that you can use and create a necessity to sell forks of different sizes.

What size are quill stems?

The most common quill diameters are 22.2, 25.4 and 28.6mm. Incompatible components can be a safety hazard, so always double-check with the manufacturer for specifications and compatibility information.

Can you convert a 1 threaded headset to Threadless?

No. Most threaded headsets are 1″ and most threadless headsets are 1 1/8″. So it physically won’t fit. The best you could do is run a converter like this to run a threadless stem, but that’s not going to do much for you.

How are threadless stems measured?

Know the length by measuring from the middle bolt of the bike’s headset top to the center of the handlebar. Ensure that you measured the length in centimeters or millimeters. A bike stem length usually runs in 10 mm increments and starts from 70 mm to 140 mm.

Are quill stems as strong as the real thing?

However, a standard quill stem or threadless adapter has exactly 0mm thickness there, making the innicycle design infinitely stronger 😉 If you take some calipers to an aluminum bike frame (seat tubes are easy to check because you know the ID from the seat post diameter) you’ll find that they aren’t exactly beefy either.

Can you cut a thread off a quill stem?

No thread cuts except in built-up areas for 5mm bolts. A regular quill stem, and by extension a good forged quill adapter, may flex a bit from the coupling but it won’t fail by cracking or shearing off. Thanks for putting some good thought into your critique!

What is the thinnest part of a quill stem?

Thinnest section is faceplate at > 2 mm, but elsewhere > 2.5 mm. No thread cuts except in built-up areas for 5mm bolts. A regular quill stem, and by extension a good forged quill adapter, may flex a bit from the coupling but it won’t fail by cracking or shearing off.

Can you get quill stems with clamp bars?

While there is a decent selection of bars and quill stems for the average male rider, it is pretty much impossible to get quill stems and matching 25.4/26.0 clamp bars for shorter riders who need shorter stems and narrower or more compact bars. I thought the same thing, but I think it’s about practicality of adjusting the fit.
