Profile Design Aerobar Bracket Riser Kit Black

clip on bars are always too close the handlebars. Take a look at actual tri/tt setups. They are much higher.Adding the risers was very easy. They look like a dedicated part of the bars.The risers made it much easier to align the bars to the right position during my last bike fit. I'm much more aero and produce more power from a more comfortable position.

Just what I needed.

I have installed these risers on both my bike (Pro Design T3+ aero bars) and my wife's bike (Oval 350 aero bars) with excellent results. They dramatically improved the comfort of riding in the aero position. On my 30 minute loop, I went from being able to maintain an aero position for 5-10 minutes to being able to maintain 25+ minutes on the bars without discomfort. This is a huge improvement.A couple of things to note about using these Pro Design risers with other brand bars. Using the Oval 350 bars as an example, you must check the size of the handlebar tubes and the aero bar bolts.These risers are designed for round handlebar tubes where the stem mount clamps them. There are two pretty standard size handle bar tube sizes (smaller and larger). These risers fit the larger. If you have the smaller, your existing shims should fit nicely.The second issue is the bolts. These risers come with M6 bolts to fit. Some existing aero bars are clamped on using M5 or other sized bolts. I don't know if you can find the 70mm long M6 bolts at the hardware store, so you should be careful to check your "bolt size" before buying.I used my M6 tapping bits to enlarge the existing M5 threaded holes on the Oval 350 aero bars. This worked nicely. I did have to use a larger bit to bore out a recess for the M6 bolt head. This worked very nicely, but it does require some tapping bits and a little DIY modification. If you screw it up, you cannot go back to the smaller holes.THINKWORK Combination Drill Tap & Tap Bit Set, 3-in-1 Titanium Coated Screw Tapping Bit.Overall, both my wife and I found the 70mm rise made a huge comfort improvement.

This was a perfect addition to my Redshift Aero Bars to get them to a comfortable height for a multi-day endurance ride. Great quality and packaging and very easy to install

These things do what they say. They are also ridiculously over-engineered. There is no reason for the 50mm riser to weigh 150g for a set. There is no reason for these to be made of aluminum with such thick walls. They could be nylon or GFRP and weigh less than half. I drilled some lightening holes in them, and it saved just 15g total.

Excelente, 70 Mm, mejora la posición, la comodidad, la aerodinámica, acoplan de manera perfecta, no necesita herramientas ni conocimiento especializado, se recomienda realizar bikefiting después de instalados

The riser kit is the perfect addition for bring the aero bars up to a comfortable height. They aren't exactly light, but they are most effective when those Profile bars need to be higher.

You never know if what you’re buying on Amazon is going to be high quality material, or seem so and then break a year later. These spacers are phenomenally built and I couldn’t recommend them more to those in need. Be specific about your height!
