Slip Grip bike mount

Well my new bike mount for my iPhone came in last night and I couldn’t be happier with it. This mount is specifically designed to hold the iPhone 4 in an Otterbox Defender series case. This eliminates having to take the phone out of the case when I ride and putting it back when I’m done. In addition, I feel a lot better knowing that if I wipe out, my phone stands a good chance of not being damaged.

Out of the box, it comes with no instructions but non is really needed as it is a simple hinge, shaped to fit the handlebar, with a nut at the other end. I disassembled it and took a picture of the parts. Assembly was just as easy, open hinge, find a spot on your handlebar to mount it, use rubber shims and tighten. It does come with two rubber shims and I used one for my T-Bar. About the only problem I had installing the mount was getting it to clamp enough around the T-Bar, so I can thread the nut at the bottom. I ended up cutting the rubber shim about a centimeter so that it would fit on one half of the clamp. After doing that, it had enough clearance to clamp it and tighten it with the bottom nut. After testing to see if I can move the mount, I found that it has a tight grip on the bar and will not budge.

It does a swivel to adjust the angle any way you see fit and you can lock it in that position. That along with the camera hole, on the mount, allows you to use it to take pictures or videos as you ride. That’s a nice feature that didn’t cross my mind until now. You also have full access to the iPhone volume, headphone and data port all while it is securely held in place. Mounting the iPhone with the Otterbox Defender series case is as simple as snapping it on. It is held in place with a large tension lever.

The Slip Grip, made in the U.S.A. and they do make them for other phones and cases such as the iPhone 3GS and the Otterbox Defender for that phone. I bought this unit on eBay for $35.95 plus $4.95 for shipping. I searched Amazon but they only had the 3GS version, so I went with eBay. Would I recommend this to my friends? Yes I would. The iPhone 4 is expensive and I want to take good care of it. Using this bike mount that allows me to keep my protective case on while cycling is important to me. Combine that with easy installation and a secure non slipping mount make this a good buy.

Just a quick note to let the readers know that I still use the Slip Grip and love it. On a group ride, one time, someone with a Samsung Android phone was able to secure their phone on the same mount. Not a perfect fit, but it snapped into place and was secure in the mount. So, for those cyclists with Android phones this is a good alternative to securely mount your phone and use it as bike computer. Just an idea …

Anyone else use the Slip Grip? Post your comments and experience with it.

Update: 08/20/2011

After six months of use, the bike mount broke, sort of. I noticed that the phone was starting to turn sideways, so I figured I would tighten the knob at the joint. Doing so, I stripped the screw to the point where it would tighten only to a certain point then would loosen its grip again. I took the whole thing off the bike so I could take a closer look at it and see if I could fix it. I could not figure out how to take apart the ball joint, but I did come up with an idea. Insert some shims between the ball and the cup, so I found the double sided tape that is used to mount a third eye mirror to the helmet and decided to use that. It was no longer sticky with glue, so I didn’t have to worry about gumming up the joint. Cutting it half and inserting it between the ball and joint seemed to be the right thickness as I was able to tighten up the joint, but being careful not to over tighten it.

I went out for a 14 mile ride to test out the repairs. For the most part it seemed to work. About the half way mark the unit did start to droop down. I nudged it back into place and kept on riding. Going over some bumps and jarring the bike produced the droop back again. This time I adjusted the unit more perpendicular to the stem and that seemed to do the trick. The rest of the ride was uneventful as the unit stayed in place.

Not satisfied with the results, I was thinking of a better shim to use and the thought came to me as I was riding home. Use the rubber of an old tube! That should provide the needed friction to hold it in place. Once I got back home, I dug up my heavily patched spare tube and started cutting. I cut out several strips about an inch long and 1/2 inch wide. Loosening the elbow screw the max, I inserted the shims on either side of the ball joint. I folded one shim and left the other straight. Initially, tried to fold both shims but could not insert both of them, but you may be able to yourself. Aligning the bracket to where I wanted it, I then tighten the elbow screw being careful not to over tighten it. At this point the cup/ball joint looked to be solid.

I went ahead and mounted the unit back on my bike and took it out for a 14 mile spin and found that it was a much better solution for the problem. Now, I just need to ride and see how long this works. It would be nice if they made one without the ball joint and used a clip on bracket like what is used for the bike lights.

Drop me a comment if you had problems with this mount and what you did to fix it.

  1. Slip Grip Bike Holder clamp was hard to tighten securely, bottom clamp has started to crack and only lasted 7 months. Swivel clamp loosens with vibration and changes angle going over bumps. When I contacted Slip Grip, they want me to pay $15.00 plus shipping to replace it the bottom bracket, almost the cost of buying a new one. 🙁

    • Hi Allen,

      Thanks for the feedback. So far for me it has been working pretty good. Occationally, the swivel will loosens, as you mentioned, but I just retighten it again. I do that about once a month.

      For the crack on the handlebar clamp that’s a bummer. Initially, I had a hard time clamping the unit on my T-bar using the provided shim, but I cut the shim to fit on only one side of the clamp and that worked perfectly for me. I do a lot of road riding with the occational rail road track or the intersection bumps and it seems pretty solid for me. I don’t know why they won’t send you the bottom part of the bracket since it’s hinged. How did you get hold of them? I never found an official webpage for them.

  2. Hi Allen,

    Had it. Liked it. Would get another one but the handlebar mount needs to be more ‘ruggedized’ for mountain biking. Or to be more specific, better to handle the rough spots while mountain biking. ie crashing 😉 It was good, but it took one crash to render the handlebar, screw-mount cracked. If they could beef up the plastic there or even make it metal so that the upper portion breaks-away on impact, sort of like a ski-boot, it would be much more attractive to purchase again.
    Since then, i’ve found nothing more suitable.

  3. Also having durability issues, now I have a broken iPhone 4S, broken Otterbox Case and broken Slip Grip Mount. This is a good mount for light use and smooth sailing. If you live anywhere in America then your roads are probably bumpy with potholes and cracks and this mount is not secure enough for daily use. A few times the phone has been ejected from holder going over bumps in the road. Luckily the Otterbox case did it’s job and protected the phone.

    Today I got into a minor crash (I rear ended someone who stopped short 100 yrs from a red light) and the actual mount broke at the swivel. Unfortunately I didn’t notice at first and when I went back the phone had been run over. The holder, still-attached to the OB case, created a lump in the center of the phone which made the run over damage way worse. My iphone is curved like a Banana now.

    I have two other accessories attached to my handle bars, a bell and a bike light. Both of them have stayed rock solid for years and in total both were cheaper than just the Slip Grip mount. For mounting the most expensive item on my bars I want a mount that is the most solid. I have contacted Slip Grip in the past with comments and suggestions about making the mount better but they have never responded.
