PRO’s all-new Compact Carbon Clip-On places a brand new form on the smallest of miniature clip-on aero bar extensions, with built-in pc & accent mounts. As a long-time bar of alt bars – and of merely stretching out over my bars to provide my fingers a break on long-distance rides – I’m at all times recreation to check out a brand new bar. And whereas a full-size set of clip-on aero bars really feel a bit misplaced on something however a time trial rig, these mini Compact Clip-Ons ship lots of the similar aero & consolation advantages in one thing that’s not a lot larger than some out-front GPS mounts….
Assessment: PRO Compact Clip-On mini aero bar
The primary query you must ask your self if you end up about to bolt an aero bar onto a gravel bike is why? As a result of your using buddies are going to ask you too, so that you would possibly as nicely be ready with a great reply to stave off any ridicule. Let’s be sincere, aero bars are humorous on any bike that’s not a time trial or triathlon bike.
However with the rise of ultra-endurance all-road races, ultra-distance gravel bike races, and even simply multi-day bikepacking rides – a clip on aero bar does double obligation. One, it helps you get right into a extra aero using place for lengthy, straight stretches into the winds. And two, it offers your fingers a much-needed break from having to assist your higher physique weight for lengthy sustained intervals.
Into the main points
PRO Bike Parts simply debuted their all-new PRO Compact Carbon Clip-On mini aerobar extension final Friday, alongside their lightest ever Vibe SL highway bar.
It’s an extremely easy product. A pair of 2-piece 31.8mm alloy clamps on both aspect of your stem, safe a ~10cm lengthy carbon loop in entrance of your bar providing you with a extra slim and extra ahead place to relaxation your fingers with out sacrificing steering management.
It doesn’t lengthen additional as PRO wished to make sure this may very well be utilized in mass-start evens that prohibit any protrusion past the entrance of your common brake/shift hoods/levers.
The entire thing weighs simply 135g (claimed), together with a built-in GPS biking pc mount on prime, and a 2-bolt accent mount beneath that may assist a GoPro, gentle, or an additional out-front GPS mount should you desire. The UD T700 carbon loop sells for $180 / 160€, and is appropriate with most (however not all) spherical prime highway & gravel dropbars.
How does it work? And what’s so particular?
Bear in mind, it’s a easy, small setup – and an additional refinement of a product we seen round since 2018. In truth, it is extremely much like the Farr Carbon Aero Bolt-On that we reviewed final autumn. From the entrance, it’s slightly unobtrusive.
What actually units it aside from Farr’s unique Aero Bolt-On is the PRO’s extra angular form and built-in accent mounts.
Moreover, the PRO Compact Carbon Clip-On has a brief flat part proper on the bar, then ramps up with a extra outstanding ~4cm of rise. That greater angle makes more room in your fingers and reduces the necessity to over-rotate your wrists to take care of a great grip on the entrance loop. In truth, Farr already reshaped their latest, longer Carbon Aero Bolt-On Massive with related ramping.
That upward angled form means you don’t get fairly as low, however it’s ergonomically extra comfy, so I used to be in a position to preserve this tucked place longer and over extra diversified highway surfaces.
Improved aero hand positions
The graceful, large hexagonal form created contained in the PRO Compact Carbon Clip-On extension loop provided a surprisingly versatile spot to position my fingers. Subtly grippy printed-on texture let me maintain my fingers comfortably both all the best way ahead with my thumbs pressed up towards the entrance of the loop (above) or slid again with my final fingers hooked over the widest a part of the mini aero bar (beneath).
At nearly 10cm center-center in entrance of the primary handlebar although, I actually wasn’t in a position to get tremendous low or tremendous aero. In truth, my wrist primarily ended up sitting on the tops of the bar, and I couldn’t tuck my elbows in, lest I scorching them with my knees whereas pedaling.
That is primarily the identical limitation I had final yr testing the unique Farr carbon loop. And whereas the match of my fingers inside this PRO clip-on is far more comfy – this nonetheless isn’t a real alternative for correct aerobar extensions.
I did actually just like the neat built-in pc mounting – which even labored nicely with my massive Wahoo Roam GPS with out it getting in the best way of my fingers. And for long-distance gravel adventures, I’m assured that I may mount a small bar bag below the loop and nonetheless use an out-front mount from the underside bolts to mount a headlight in entrance of the bag. That’s a surprisingly frequent dilemma to resolve (bikepacking bar bag + bike-mounted headlight), so it’s good to see a couple of accent mount right here.
The opposite factor is that, despite the fact that the PRO Compact Carbon Clip-On isn’t long-enough for a full aero tuck, I’m already used to simply resting my forearms on the tops of my padded bars with nothing to carry onto. (Clearly, that’s not tremendous secure, and is why the UCI has banned the imaginary aerobar tuck).
However now I can do my imaginary tuck and truly have one thing to lean and leverage towards for improved security & a modicum of management (see my full imaginary aerobar tuck within the picture at the highest of this evaluate).
However does it make you quicker?
In fact, it makes me sooner. See that smaller frontal space and deeper aero tuck after I’m sprinting head-to-head towards my gravel buddies (above)!
OK, possibly the Compact Carbon Clip-On doesn’t make me magically, quantifiably sooner. However I actually admire the additional hand positions, particularly after I’m grinding out a couple of days of mixed-surface using in a row. Plus, the load penalty is fairly minor, and the 2 built-in accent mounts are a giant plus. Would I desire it to be about 5cm longer… sure.
However there are actually deserves to this compact measurement, as nicely.
