Good looking bar, coating feels premium and hopefully durable. 40mm rise makes my Whyte far more comfortable on the shoulders. Not ridden with it much yet, but happy so far

As a big guy, my hands start to hurt and go numb from lack of core strength. I tried the pnw bars with 30mm rise first. The 40mm rise bars and 35mm stem completed my search for a comfortable cockpit. I've ridden 30 trail miles with these bars. No discomfort in my hands. I hope these work for you like they did for me. Plus they look so good on my bike.

Excellent bar. Great quality. Light. Strong. Used it for both of my boys bikes. Bought the 30mm rise to help the boys sit a little more upright and have less weight over the bars.
They look the part & match the fork stanchions enhancing the look of the bike. I like the colour and finish. A bit expensive though for a piece of aluminium but my son looks on in envy so worth the money. He's already messaging me with his next upgrade. Ahh the fun of one-upmanship.
These bars have completely changed how my Trek Roscoe 8 performs. I was hoping for just a noticeable difference, but got a big time difference. I always went with Renthal bars on my dirt bikes (back in the day). Im still a newbie to mountain biking and this small upgrade has given me a lot more confidence (which you need when your about to turn 55).
Three years on mine with no crashes warranting replacement for safety concerns. Feels great. Looks like da bomb. Comfy. Highly recommended. Renthal is a brand that I trust. Easier to make narrower with a bargain pipe-cutter.
Buy online without having a third party opinion! I was impressed that they met the delivery date! Now I have my 30 rise renthal fatbar handlebar! Amazed! And I also mention that it was much cheaper! 100% recommendable! Bikeinn a 7!
They simply work as intended. Highly accurate manufacturing along with excellent material specification, if you want aluminium bars as opposed to carbon fibre these should be a reference. Not only look good but their intended flex pattern and characteristics make a very high performance product at a low weight.
The product I wanted was available at a good price at Start Fitness and delivery was very fast. I wanted to increase the rise of my bars from 25mm to 40mm, but these bars also gave me an increase in width from 780mm to 800mm and altered bar geometry (reduced back sweep from 9 to 7 degrees). My initial impressions were that the ride felt really good with the new bars, both uphill and downhill. I felt I had a bit more control and breathing space when climbing, and when descending I found the bars put me naturally in a better position on the bike. Renthal Fatbar seemed to be the go to bar to try, and I haven't been disappointed.

Renthal Fatbar Handlebar - Black 31.8mm 800mm - 40mm
Renthal Fatbar V2 31.8mm The Renthal Fatbar is the ultimate aluminium downhill race handlebar. Renthal designed the Fatbar to be the ultimate combination of lightness, strength and durability. With much lower weight, this all-new Fatbar is now ideally suited for trail bike use, where a super-wide handlebar is required. With much lower weight, this all-new Fatbar is now ideally suited for trail bike use, where a super-wide handlebar is required. Race Weight The all new Fatbar is at a much lower weight of just 315g. This has been achieved with more efficient use of material, removing any excess to reduce weight, whilst retaining the strength, durability and flex characteristics of the original Fatbar. Race Geometry As well as reducing weight, width is also increased up to a full 800mm. The Fatbar features proven 7° back sweep / 5° up sweep combination and is available in 10, 20, 30 and 40mm rise options, to suit any bike and any rider preference. All rise options are also available in both 31.8mm and 35mm diameters. Race Winning The Renthal Fatbar has already gained cult status, as the aluminium handlebar of choice for World Cup downhill. Eight World Championship gold medals have been won using the Fatbar, cementing it as one of the most successful race products of all time. Aluminium Tech The Renthal Fatbar is constructed from exclusive, high strength, 7 series aluminium. The material and specific heat treatment processes have been carefully selected to give the ultimate in strength and durability. Ultra Durable Millions of tiny steel shot are blasted at high velocity at the Fatbar, leaving a textured surface finish. This shot peening process vastly increases the fatigue life and hence durability of the handlebar. Hard Anodised The Fatbar features a hard anodising surface treatment. This finish is far superior in abrasion resistance to standard anodising, to keep your handlebar looking new.
