Profile Designs Aerobar Bracket Riser Kit Black

The 70mm aluminum risers raise the aerobars roughly 2 1/4 inches. Though not intended, these risers work with my 2014 Felt B14 handlebars.These risers made a world of difference for several reasons. Stock on my B14, the elbow pads sat flush on the handlebars, making it difficult to grab the inner potion of the handlebars. The risers create space between the aerobars and handlebars, allowing full grip of the handlebar. By using these risers, I was able to remove some spacers from the stem. This lowered the handlebars but raised the elbow pads and aerobars, greatly increasing the usability of the cockpit.Also, raising the elbow pads / aerobars added quite a bit of comfort. I'm able to crush longer rides without strain or pain. By removing the spacers at the stem, I'm still getting significant aero gains–however, if I want to get an even more aggressive position in the future, I may purchase the 40mm or 50mm set. Totally worth the money for these risers–one of the best upgrades I've done.

I'm glad I ordered this 70mm height, it's just what I needed. I do endurance rides of 60 to 100 miles and I was getting wrist pain on my Giant TCR. So I threw on my aerobars so that I could put my upper body weight on my elbows rather than my hands during the flat straight sections of the ride. But without spacers, it was a position too aggressive for me to maintain. When using my aerobars with these 70mm risers, I get a position that has me bent over an equivalent amount to my hands being in the drops of the handlebars. This is a position that I can hold for a while and my hands and wrists are already feeling much better.

Profile redesigned the elbow rests for the T3+ aerobars and made a right mess of it. The aerobars now cover far too much of the handlebars and you can no longer rotate the elbow pads up away from the bars. If you want to ride with your hands on the flats you have to buy these risers that lift the entire aerobar up.It took so long for them to ship, I 3D printed my own 30mm risers with carbon fiber PETG (100% infill) and paid $5 for eight 45mm M6 bolts (I made some for my daughter too). Mine were probably not as strong as these but I used them for 100 miles without any problems. Mine cost about $10 for two pairs - these cost over $50.They are really difficult to install. If you have handlebar shims, like me, you have to hold 6 things in place with one hand while tightening the bolt with the other. A bit of electrical tape to hold the shims in place makes things a lot easier.Considering these are just a fix for a bad design, they cost too much and took too long to ship.

Takes about 1/2 hour to install - requires holding a few components together with one hand and using an Allen wrench to fasten them together. A third hand might be helpful.Not much to the item (as shown) but it's extremely solid. Good solution for indoor riding but it should be great for outdoor as well.FYI: the first time my purchase was delivered, the package did not include all the parts, nor was the cardboard items for holding the components together in the (opened and unsealed) bag included. I don't know what they're thinking sending this crap out. They replaced it right away but you have to get the original item back to UPS to complete the replacement.

I bought these from amazon, to go with my first set of aerobars, without being able to try in person first. I purchased the 40mm size hoping these would raise the aerobars enough so that I could continue to use the flat part of my road bike handlebars as I normally do without aerobars installed. These definitely accomplished that. Using these 40mm risers, there is plenty of room for my hands underneath the forearm rests of the aerobars. If I could do it again, I would order the 30mm size instead without hesitation (possible even the 20mm) so the aerobars would be lower and still fit my hands underneath. The bolts that it came with worked fine. It's currently winter, so I have not ridden my bike with these yet, but I suspect will work fine.

I bought the 70mm riser to mount the Profile Design Jammer GT on my Trek 520. The risers are top notch. Fit perfectly and the bolts came pre-treated with blue locktite but came with no washers (to save 2 cents?) and that's why I took off 1 star.

Yes, these do fit on the Profile Design Air Stryke II aero bars.My new bike has the seat raised 2" so I got the 50mm size to bring up the elbow pads. I just transferred the washers from the original bolts to the new ones, they stick right through the risers into the bracket for the elbow pads.I have yet to take them for a ride, so we'll see how it goes. I'll update if needed.

I have these aerobars setup on a mountain bike for bikepacking. I couldn't get comfortable in them, because a MTB geometry isn't the same as a road bike when you lean over. With putting these risers on, it fixed the comfort problem, and allowed me to stay in the aero position longer during my 300 mile bikepacking trip. Definitely recommend for anyone looking for a little more comfort on their ride.

Well made, but not much for the money. Although it didn't claim to be any more.Using mine for a competitor's tri bar and it will need modifying. So best avoided if it is not for a Profile bar.

Very good

Great product

Bought these for my Profile Legacy aerobars. Most reviews mentioned that they were not compatible with these bars. I took a chance and I can understand why they're not intended for the Legacy I. The risers end up mounting the bars on a cool looking 45° forward angle that doesn't alter my riding position too much. A side bonus is that there is more room for my phone mount (which locks onto the headset screw).All in all, they work great for my aerobars.

Funktioniert bestens, aber der Preis ist für so ein simples Stück Metall schon dreist. Besonders, wenn man verschiedene Höhen probiert um die richtige zu finden.
