Bike from a listing

Buying this bike second-hand? Enter the size, stem and spacers actually on the bike to see whether it fits you.

Selling it? Fill in the details and paste the link into your listing. Buyers will see where the bars end up, based on what you enter.

How do I measure it?

Cover + spacers: measure from the top of the head tube to the underside of the stem. That’s the headset cover plus any spacers. Length and angle are usually printed on the stem (−6° is typical, with the stem pointing down). Bar reach is on the bar manufacturer’s website. If you can’t find it, leave it at 75 mm. Spacers above the stem show how much higher the stem could still go. Leave that blank and I’ll assume it can’t go any higher.

Is it an integrated cockpit, a one-piece bar and stem? Then the stem may not be swappable. Check with the seller.
