I got back on the bike yesterday. My legs actually felt very good. While on the bike, my shoulder did not hurt me at all. Only when I lift my arm up to my head do I feel a tinge of soreness. Sorest were my middle and ring fingers on my right hand. At first I couldn’t figure out why, then it hit me… the iBike.
When I fell on Saturday, I had my right hand turned with my index finger on the left side of the Garmin Edge 500 with my thumb on the right side. The abrupt fall caused my right hand to “punch” the iBike computer with my hand. It would appear that it was the aforementioned fingers that took the brunt of the punch.
Still, it was the iBike that got the worse of it. The small hard plastic strap that screws into the wireless mount base broke in two. This didn’t surprise me at all. This wasn’t the first time I’ve had this mount break. At least it was the strap only this time and not the base itself as I have had happen before.
It got me to thinking of an alternative to the mount. I really like the new Garmin mount. It uses large rubber O-rings to mount the base to the bike. This makes is much more versatile and less likely to break. I wondered if I might be able to take a similar approach with the iBike.
The iBike mount has two “knobs” that stick out on either side of the base. These contain the threads into which the strap (seen above in the first picture) is attached with screws. I’ve had one of these knobs break off before.
So, I decided to see if I could loop one of my extra Garmin O-rings around one of the knobs, run it under the stem, and then around the second knob. I also placed some two-sided tape on the bottom of the mount to help keep it in place. Right off the bat, I saw some potential.
I still didn’t feel overly confident with the setup. The potential that the O-ring could pop off of the rounded edges of the knobs was real. If I could just find a way to hold the rubber in place, I couldn’t see any reason why this wouldn’t work.
A second O-ring solved my problem. It worked by running a second O-ring over the first one around one knob, routing it over the stem, and then over the bottom O-ring and around the second knob. You can see the demonstration in the photo above.
Now, I realize that one reason iBike has such a rigid mounting system is because the consistency of its placement is important to the proper function of the unit. While it is possible that this method for mounting the computer might not work, I am willing to give it a try. My first experience was positive.
During my ride, I made sure I went over some rough sections of road. I tested various efforts. In every case the unit stayed in place and the wattage registered was consistent with my expectations. The only thing I had to be careful about was putting the unit on and taking it off.
It takes a bit of torque to snap the computer to the mount. It could be possible that I could twist the mount a bit in the process. That would weaken the tape as the O-rings flex. This is easily countered by holding the base with my left hand while I attach/detach the computer with my right.
So, why did I do this instead of ordering a new base strap? I will order a replacement, but I needed it last night. Plus, I’ve never been a fan of that system. It is awkward and prone to breaking because of the stresses caused by the rigidity. IF this method works, I may not replace it.
I’m open to reasons why this isn’t a good idea. I will keep testing the concept to see if I experience any long-term issues. I’ll let you know!
