Ideal for riders wanting a more upright, adaptable cockpit on a road bike, flat-bar fitness bike, hybrid or older MTB with a standard 1 1/8" threadless front end.
If your current position feels too low, too stretched out, or just not quite right, the XLC Comp A-Head ST-T14 gives you a much easier way to dial it in. This is an adjustable A-head stem for bikes using a 1 1/8" steerer and 31.8 mm handlebar clamp, with a wide 0–60° angle range that lets you lift the bars for a more upright setup or fine-tune reach and hand position around your preferred fit.
For commuting, fitness riding, light road use and general MTB or hybrid setups, an adjustable stem like this can make a noticeable difference to comfort. Raising the bar position can help reduce strain through the neck, shoulders, wrists and lower back, especially if you’re trying to make an older bike fit better without swapping frames or bars. The forged aluminium construction keeps it practical and sturdy, and the tool-free angle adjustment is handy if you’re still working out your ideal position.
We’d choose this stem for riders who value fit flexibility over minimal weight. At 252 g it isn’t a featherweight race part, but that’s not the point here — it’s a straightforward cockpit upgrade that gives you more room to experiment and settle on a position you can actually ride comfortably for longer.
0–60° adjustable angle
Lets you fine-tune handlebar height and reach far more than a fixed-angle stem.
Tool-free angle adjustment
Quick to tweak when you’re experimenting with fit or sharing a bike between riders.
31.8 mm handlebar clamp
Matches the most common modern oversize handlebar centre diameter.
1 1/8" A-head steerer fit
Works with the standard threadless steerer size found on many modern and recent bikes.
110 mm length
Suited to riders who want adjustment without going to an ultra-short cockpit feel.
2D-forged aluminium construction
Keeps the stem strong and practical for everyday use.
Race/MTB use category
Versatile enough for a range of bikes where comfort and position tuning matter more than outright weight.

Features
Great for
Maybe not for
This version is 110 mm long and fits a 1 1/8" threadless steerer with a 31.8 mm handlebar clamp. The listed clamp height is 35 mm, so check available steerer tube above the headset before buying. An adjustable stem is best when you’re using it to refine comfort rather than create an extreme performance position.
vs BBB HighSix 31.8mm adjustable handlebar stem
A close alternative for riders wanting an adjustable 31.8 mm threadless stem with a slightly different angle range and broader current certification details.
vs Ergotec Sepia Ahead XL/31.8
A heavier-duty adjustable Ahead stem aimed more at comfort, trekking and higher-load use.
vs Bontrager Blendr Adjustable Threadless Stem
A more accessory-oriented alternative for riders who want integrated mounting around a modern commuter or fitness setup.
Best used as a fit-fix, not a handling shortcut
This kind of stem is ideal when your bars feel a touch low or your position is too aggressive. It’s much better for comfort tuning than for changing a bike’s character completely.
Check both key interfaces before ordering
You need a 1 1/8" threadless steerer and a 31.8 mm handlebar centre section. If either measurement is different, this stem isn’t the right match.
Mind the steerer length
Because the stem has a 35 mm clamp height, make sure you have enough usable steerer tube above the headset for safe clamping and preload setup.
A good option for older bikes using oversize bars
If you’ve already moved to a 31.8 mm handlebar on an older hardtail, hybrid or flat-bar road bike, this stem gives you a lot more room to refine position than a fixed-angle stem.
