Here’s how to mount a VeloView Prism using either a Narrow Acrylic plate and a pair of GUB G-23 water bottle mounts; or a ‘T’ Shaped Acrylic plate and one GUB G-88 cell phone mount. Additionally, the plates give you a platform for mounting a phone or GPS unit.
Comments & Testimonials
I like this prism because
it gives me a constant view of what’s ahead of me when using aerobars on my road bike without straining my neck. The field of view is somewhat limited due to the nature of prisms but it is adequate for my needs.

In addition to the huge benefit in neck comfort,
Sam NavonMD, PhD, FACS, Chief, Cornea and Refractive Surgery, Cleveland Clinic Abu Dhabi
I bike on heavily traveled roads
and I am constantly aware of my surroundings which means I keep my eyes moving from my rear view mirror to my prism and checking for other traffic which includes side streets and turning traffic.

I Ride Faster with VeloView Prism
I have been riding with the VeloView Prism for over a year. It has dramatically improved my speed when I am pulling. I cannot imagine riding without my VeloView Prism.
I have also watched other riders lose focus on the road and almost hit objects in the road. This not only creates a risk for them but also creates risk for those following.

Prior to having a prism
I had a close encounter with a large truck parked in my bike lane. Fortunately I was able to stop in time but that one experience was enough motivation for me to seek out this prism and it serves its purpose.

Comme un avantage sur la sécurité.
J’ai décidé d’essayer “VeloView” qui est un prisme attaché au guidon, ce qui nous permet de voir ce qui se trouve devant soi lorsque nous sommes en position aérodynamique la tête baissée. C’est un outil secondaire puisque nous devons toujours avoir conscience de ce qui nous entoure, mais la sécurité accrue est un facteur important. Merci.

I have been using the VeloView for about 6 months
and have enjoyed it very much. I particularly like it when I am on long straightaways or riding into the wind.

Is it big enough to give a useful field of view?
Is it hard to get used to?
Just like using a rear view mirror, there is a learning curve. You first learn to trust it, then you learn to not depend on it.
Does it block your field of view?
And yes, that’s where I mount my water bottle!

VeloView Prism Keeps Your Eyes On the Road
While Your Head Is Down! February 9, 2017 By
Cyclists that use Aerobars for a more comfortable and aerodynamic riding position, that would like to keep their head down for longer periods of time without the need to check the road ahead. Are sure to be interested in a new product which has been created by Carl Panek and Larry Leventhal.
The VeloView Prism has been designed specifically for bicycle Aerobars and allows you to keep your head down while still being able to view the road ahead, giving you an aerodynamic advantage over your competitors who still have to raise their heads to check the road ahead.
Shermer's Neck? What the Heck?
Danhaus was about 1,000 miles into the 2009 race, rolling through the plains of Kansas, when he suddenly felt something weird.
“I just remember I was just having trouble keeping my head up,” Danhaus said. “I was thinking ‘Geez, I must be tired.’ And then it dawned on me.”
He may have been tired, but that wasn’t why his head wasn’t staying up. Instead, Danhaus was suffering from Shermer’s Neck, a fascinating ailment that affects cyclists who ride unusually long distances.
To sum it up cleanly, Shermer’s Neck is a condition where the neck muscles fail from fatigue and can no longer support the head. It is not a gradual ailment, either: after first feeling the symptoms, the neck will usually give out within two hours.
Danhaus had about an hour’s notice before his neck stopped working. He still had about 2,000 miles left in the race.
One of those competitors was Michael Shermer. He finished the race in 1982 (though he didn’t win) and tried it again in 1983. About 2,000 miles into the ’83 race, Shermer suddenly was unable to hold his head up, and he was forced to prop his chin up with the palm of his hand to keep going.
A new medical condition—called “Shermer’s Neck”—was named, and all it took was a 3,000-mile nonstop bike ride across the vast United States to discover it.
It is a rare ailment for endurance athletes simply because most will never be on a bike for the 500-plus mile minimum it takes for Shermer’s Neck to pop up. Even then, Shermer’s Neck doesn’t happen to most ultra-distance competitors. But it does frequently pop up among participants in both the Race Across America and Paris-Brest-Paris, a famous 1,200K brevet (745 miles) in France.
Though what exactly causes it isn’t fully known, theories like posture on the bike have been discussed.
But just knowing the possibility of Shermer’s Neck exists forces most ultra-distance cyclists to have a solution in place to deal with it.
“I had planned in case it would happen,” Danhaus said, “but I sure did not think I would be affected with it. I never had any of those kinds of problems at all.”
“I’ve read accounts of people that quit because of the pain,” Danhaus said. “I tend to be pretty good at blocking pain out. At RAAM, I was so hyped up that nothing would stop me from finishing.”
For Danhaus, it was simply a case of the neck refusing to hold the head up any longer. In most cases during ultra-distance bike races, Shermer’s Neck does not go away for the remainder of the ride.
But most of the time, cyclists continue on despite the muscle failure. In that regard, Danhaus says that Shermer’s Neck is more of a bizarre ailment rather than a crippling one. To him, compared to major saddle sores or hip problems or knee problems, Shermer’s Neck is no big deal.
That is, if you’re prepared for it.
Solutions on the Bike
A member of Danhaus’ crew tried this, but the crosswinds of the Great Plains made it ineffective, because Danhaus’ head kept rocking from side to side. So he dismounted and the crew huddled up.
“I said, ‘Well, take my aero bars and rotate them up,'” Danhaus said.
The crew shifted his aero bars so they were straight above the handlebars, then wrapped the top of them with toilet paper and covered the toilet paper in duct tape to keep it in place. Danhaus then put his chin on top of the contraption and kept riding.
A simple Google image search of Shermer’s Neck shows other creative ways to work around the ailment, including one that combines the Danhaus crew’s two ideas and sends a metal pole up the back, then has an elastic band wrapping around each side of the cyclist’s head that form a chin strap to rest the head on.
Another example was discussed in the New York Times involving female competitor Leah Goldstein. When her neck failed, her crew braided tape into her hair and tied it to her heart-rate montior or bra to prop her head up.
By that point, his body was used to the sleep deprivation. He fell asleep after the race finished but only got two hours in before waking up. And his neck still wasn’t working.
“On the drive home, I stopped at a drug store and got one of those neck collars for whiplash to help keep my head up,” Danhaus said.
He returned to his full-time job as a veterinarian surgeon, but still had problems doing his work because his neck was not back to full strength. He frequently visited the chiropractor to try and speed up the recovery.
“It took three or four weeks before I could really keep my head up,” Danhaus said. “But even then, if I went out for six- or seven-hour bike ride, it would still be weak. It gradually returned, but it took weeks.
“I never felt pain. It was just total muscle fatigue.”
Danhaus has competed in 500-mile events since the 2009 RAAM, and has not had any problems with his neck in those rides. He’s hoping to compete in the RAAM again in the future, knowing that Shermer’s Neck might pop up once again.
For the extreme ultra-distance cyclists, it’s always a possibility.
“I’ve done many races in the 500- to 600-mile range and never had a problem. But in RAAM, it struck me at around 1,000 miles,” Danhaus said. “Until you get 1,000 miles under your belt, you don’t know what your body is going to do.”
