Its beautifully finished NITTO construction and distinctive integrated stem design give it the unmistakable silhouette of a classic bullmoose bar.

While the styling is decidedly retro, its compatibility with modern 1-1/8-inch threadless steerers makes it easy to use with contemporary chromoly bikes, touring bikes, and gravel bikes.

Whether you are converting a road bike to a flat-bar setup, restoring an old mountain bike, or building a practical bike for everyday riding, there are plenty of ways to make it work.

Beautiful Integrated Chromoly Construction by NITTO

The Distinctive Silhouette of a Bullmoose Bar

The first thing that stands out about this handlebar is the beauty of its design.

Two tubes extend from the steerer clamp and flow naturally into the handlebar, creating the characteristic shape of a bullmoose bar. It has a nostalgic yet striking presence that is difficult to achieve with a conventional stem and flat-bar combination.

Carefully Finished by NITTO

The bar is manufactured by NITTO, a Japanese company trusted by cyclists around the world. From the clean lines of the chromoly tubing to the neatly finished joints, the attention to detail is unmistakably NITTO.

The integrated construction also gives the cockpit a particularly clean and uncluttered appearance. It may not be a flashy component, but installing it can completely transform the character of a bike.

Old-School MTB Style with Modern Compatibility

More Than a Nostalgic Reproduction

The b903 Bullmoose Bar captures the atmosphere of an old-school mountain bike, but it is much more than a retro-inspired reproduction.

Its compatibility with 1-1/8-inch threadless steerers allows it to work naturally with modern chromoly frames, touring bikes, and gravel-oriented builds.

A Clean, Flat Riding Position

The riding position is comparable to combining a 90mm NITTO UI-2 stem with a flat bar featuring 15 degrees of backsweep. With almost no rise, it creates a clean, level appearance that pairs especially well with semi-sloping and horizontal top-tube frames.

It delivers the character of a classic mountain bike without looking out of place on a modern frame. That balance between old and new is something FAIRWEATHER does particularly well.

A Versatile Choice for Road, MTB, and Touring Builds

A Natural Match for Touring and Gravel Bikes

The term bullmoose bar may bring to mind a component made exclusively for mountain bikes, but this model works surprisingly well with a wide variety of bicycles.

Install it on a touring or gravel bike such as a KONA ROVE or SURLY CROSS-CHECK, and it creates a relaxed, city-friendly riding position with a completely different character from a drop-bar setup.

It is, of course, an excellent match for fully rigid mountain bikes and vintage MTBs. It is also a great option when rebuilding an older mountain bike into a practical machine for modern everyday riding.

It can also be used for a flat-bar conversion on a road bike. A bike that has become uncomfortable because of an overly aggressive riding position can be transformed into something easier to enjoy in everyday clothing.

It is an especially appealing choice for riders who want a custom build that feels distinctive and stylish without looking overly serious or performance-focused.

Practical and Easy to Use Beyond Its Good Looks

A Comfortable and Versatile 710mm Width

The b903 Bullmoose Bar makes a strong visual impression, but spend some time riding it and you will find that its practical details are just as thoughtfully considered.

The bar measures 710mm wide, giving it a stable and relaxed feel that works well for trail riding and comfortable cruising. It can also be trimmed to your preferred width when necessary.

A Natural 15-Degree Backsweep

The 15-degree backsweep places the wrists at a natural and comfortable angle. It is relaxed enough for easygoing rides without being excessive, while still providing a solid position for putting power through the bars when riding out of the saddle.

Plenty of Space for Bags and Lights

Another less obvious advantage is the generous amount of usable space around the center of the handlebar, making it easier to mount lights and handlebar bags. For commuting, city riding, and touring, this added versatility makes a real difference.

For riders who appreciate classic styling but still care about everyday practicality, this is an exceptionally well-balanced handlebar.
