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.

Sicher nicht das billigste Angebot auf dem Markt,dafür sehr gut verarbeitet.Jedes Einzelteil macht einen eertigen Eindruck,alles passt satt zusammen und zusammen mit der Erhöhung ist der Aufsatz auch kein Folterinstrument sondern bequem und auch für lange Strecken geeignet.Mein Fazit : Das Ding ist seinen Preis wert und ich würde mich nochmal dafür entscheiden.
