well, you must be the “less than 1%” from above. 
Glad to know I’m not alone.
Here’s my full review:
ok, so like I said, after finding no reviews I just got them. I ordered from overseas and got a good price. I was looking for a lightweight aerobar extension that would be minimalistic and not bulky….but still worth having. I had purchased a set of the old cinelli spinaci’s a long time ago but I rarely used them as they just weren’t comfortable, so I hoped to avoid that mistake again.
So I’ve got about 1500 miles on the carbon blast now and I definitely have an opinion. I think they are Exactly what I was looking for. For one, I’m a lightweight, so I like to keep the bike light. They are feathery at around 200 grams so it doesn’t add considerable weight to the steering cockpit. I have kept them on all rides including those around 10,000‘of climbing. I didn’t notice it when climbing hills so steep I had to be out of the saddle and swaying back and forth. On more manageable climbs, I could easily stay in the aero position and comfortably use them to help bring power in the seated position.
I mainly ride in various groups, so I wanted something to use while leading up front, dropping back to pace people back up, catching up to a break, giving myself another hand position on long rides, or obviously while riding on my own. I think they’ve worked very well in all those instances. I like that the pads are easy to slide off of and get your hands back on the hoods/brakes. I actually feel pretty comfortable in that position in a small group ride.
I really notice the difference in the aero position when my arms are tucked in. It aligns my arms well my legs. My road bike setup is very aero in the first place, so this really compliments it and brings me the full aero advantage that my bike can offer.
When I first got them I rode them on the trainer. It wasn’t comfortable as I felt like I was putting a lot of weight on my wrists. On my first ride outdoors, that all went away. I realized that on outdoor rides, the bike moves more and my core is well engaged. As such, my core holds me up and the pads are there to keep my arms in. As you can imagine though, after 20 minutes to 30 minutes or so, I do find myself shifting around. I could do shorter time trial efforts on it without issue, but I wouldn’t ride a long ride solely in that position. Again, for the shorter bursts or riding that’s broken up with climbs, they work perfectly. I wouldn’t buy these if I was a heavier guy. It would be too much weight on the wrists. I would go with the profile jammers or something similar. I personally don’t like the upright hand position of the jammers as I think that’s visual clutter. On a long ride that would be more comfortable, yet also less aero I believe. (though obviously if they are more comfortable, you’ll ride in them more and gain more aero advantage…IF you are on your own for long periods. I’m sure someone would feel the need to point that out, so there you go.) I also didn’t want to risk slamming my knees into the pads on the jammers. I’m already near the bar when I’m out of the saddle so I think I’d hit them.
Also while on the trainer, the smooth carbon bars get slick with sweaty. Even wearing gloves, I thought I would have to tape them up. However, on a long and sweaty 130+ mile ride in 95 to 100+ temps, it wasn’t a problem. As long as you have some wind movement, they don’t stay wet. I haven’t given it a second thought since being back outside for rides.
They also leave plenty of space for the hands on the tops of the bars. (not a position I ride often, but its nice that I still have the option)
My only gripe is in the design of the bolts. The bolts screw into little cylinders that slide into the main body. The problem is, you have to align those cylinders just right are you can cross thread them and mess them up. I imagine the design takes some stress off the bolt in having to be perfect, but the danger of cross threading is real. I definitely screwed up one of them trying to get the bolt in. Luckily you can just flip it over and run the screw in that way. Before reinstalling I ran the bolt all the way to the end just to fix those messed up threads. After that one, I was a little more patient and didn’t have another problem. So….just be patient and get them in right the first time! I haven’t made any adjustments since installing back in the spring and haven’t had any slippage. Do use carbon paste since you will likely be pulling up on them and you don’t want them to slip.
Hmm, anything else…???.. I really like them and would definitely endorse them. They are pricey compared to other shorties, but I think they offer a slightly different set of value in the world of form and function. Hopefully this helps others. Overseas, totalcycling.com and xxcyle.com have them around $200 right now. Most other shops are in the $240 to $290 range. Don’t expect to ever see mine in the slowtwitch classifieds. J
