Key Details

Detail Product information and buyer relevance
Brand FIFTY-FIFTY, which helps identify the exact stem.
Product type Mountain bike stem for an MTB setup.
Material 6061T6 aluminum is stated.
Length 35 mm, a short stem length that should be checked against your bike setup.
Handlebar diameter 31.8 mm, which must match the handlebar clamp size.

What to Compare Before Buying

  • Handlebar diameter: This stem is stated for 31.8 mm handlebars. Match that clamp size before choosing it.
  • Steerer tube diameter: The stated 28.6 mm (1-1/8") size needs to match the bike’s steerer tube.
  • Length: The 35 mm length is the main fit and handling-related dimension to compare with your current setup.
  • Rise: The 0-degree rise gives a flat stem profile, so compare that with the riding position you want.
  • Weight: At 132 g, the stem’s weight may matter if you are matching a specific build target.

Compatibility, Size and Fit

This stem is sized around a 31.8 mm handlebar clamp and a 28.6 mm (1-1/8") steerer tube. Those two dimensions are the main compatibility checks. The 35 mm length is also important because it affects how the stem fits into the overall cockpit layout on the bike.

Before You Decide

Confirm the handlebar clamp size, steerer tube size, and stem length before choosing an offer. Also check whether you want a 0-degree rise stem for your current bike setup.

Installation Check

When installing the stem, follow the specified tightening limits for the stem, handlebar, and steerer clamp. Do not guess at a torque value or substitute a generic one.
