Two names into one bar.

Legendary motocross component manufacturer Renthal derives its name from a mash-up of the last names of the company's two founders, Andrew Renshaw and Henry Rosenthal. The brand crossed over into the world of mountain biking in 2010, and the Renthal Fatbar Carbon represents a similar sort of hybrid: the absolute toughness of the company's proven alloy Fatbar, with the comfort and low weight afforded by carbon fiber, engineered to be your ultimate DH-ready handlebar.

Entering the world of carbon, Renthal put enormous resources into the research and refinement of the bars to ensure it would get it right the first time. Foremost, the Fatbar strikes that ergonomic sweetspot that so many bars come close to hitting but don't. Coming in at an amazing 225 grams for a 780mm-wide bar, its seven-degree backsweep and five-degree upsweep are just about perfect and take zero time to get used to. The bar is made of a unidirectional carbon fiber, chosen for its integrity and tunability, allowing engineers to dial in the right amount of flex to mitigate vibration and allow greater control, without sacrificing the stiffness or strength that is vital to a DH-worthy handlebar — so worthy, in fact, that the bar handily passes even the most rigorous of impact tests, like the EN BMX drop test, and many others.

The Renthal Fatbar Carbon is 780mm wide and comes in four different levels of rise: 10mm, 20mm, 30mm, and 40mm. It weighs approximately 225 grams, give or take a few, depending on which you choose. The bar has a seven-degree backsweep and a five-degree upsweep, and comes in one finish.

Great bars

  • Familiarity: I've used it once or twice and have initial impressions

I bought these for my fat bike, great choice so far! The bars make the ride a little less harsh and the heat loss is very noticeable.

More control, More comfort, less weight

  • Familiarity: I've put it through the wringer

Beautiful build quality, well designed with numbered hash marks for perfect, centered alignment on your stem (every pair of bars should have this!) and a dramatic increase in stiffness/dampening vs the previous aluminum bars I was using. Quicker handling and more comfort at the bike park or on the single track.

Oh and BTW, no need to upgrade to 35mm, 31.8mm is perfect. All of the various changes in MTB standards over the past 5 years the move from 31.8 to 35mm clamp diameter is one which can be labeled as essentially without any merit.

How can you figure out the amount of "rise" you need?
