ISC RacersTape – Bike Protection Tape

Pro Reviews

Reviewed by Brian Mullin aka Gram and Pastajet

Does your mountain bike get scratched or dinged up from rocks and dirt or do cables rub on the frame causing wear spots? “It’s such a fine line between stupid, and clever.”

I stumbled upon this product to protect my Ibis Mojo which is a gorgeous clear coated carbon fiber frame that is very susceptible to scratches. With the usual rocks, trees, bushes, gravel, sand, dirt and cable rubbing, we all deal with on our everyday rides it is easy for any bike frame to get scratched and dinged up.I have had many bikes that look like a bead blaster has been used on the rear triangle right in front of the rear tire. Junk gets flung up from the tire and removes paint and pretty much makes small ding marks anywhere the debris tends to get deposited.Places on the frame such as the bottom of the downtube, the outside edges of the rear triangle and the forks all take a good beating. In addition, anywhere that cables will rub can wreck havoc overtime, since they just keep rubbing in the same spot again and again. “Do you ever have deja vu Mrs. Lancaster? I don’t think so, but I could check with the kitchen.”

    As the owner of a Titus Carbon Racer X, I have the exact same concerns.

    The combination of my tire setup, a Kenda 2.35 Blue Groove DTC and a Nevegal 2.1 DTC and the decomposed granite on the trails that I ride equate to sandblasting my frame every ride.

    My initial use of frame tape proved inadequate to the task, however.

    While I DO have frame tape on the back of the seattube, the BB shell and the bottom of the downtube, my primary protection consists of the following:

    An SKS Shockboard front fender and a Planet Bike mud guard downtube fender(reverse oriented w/cutout for chainrings) to protect the downtube and BB area.
    Protecting the seattube was much more problematic, as there are no aftermarket fenders that specifically address this concern — yet.

    So, I constructed my own. I cut off the rear portion of the front fender, cut notches in the side to fit between the seat stays and glued/duct taped on an extension.
    Small weight penalty with HUGE protection. No more chips and dings — ANYwhere.

    As for cable rub locations, I also found frame tape to be woefully lacking as well.
    I am using carbon cloth chainstay protector, from Lizardskins, cut to size. While nothing lasts forever, due to it’s thickness it will be MUCH easier to check wear and relace BEFORE it is worn through. I tried doubling the frametape in these locations and found that it was a negligible improvement and it was still VERY difficult to determine if it had worn through…..

    I think that for a lot of folks, frame tape is adequate, especially for roadbikes.
    In highly abrasive conditions and in cable rub locations it is not up to the task, I’m afraid. Unless you want to totaly replace it every 200 miles or so, I’d recommend some fenders.

    Happy Trails,

    With regards to crankskins:
    Not sure about being cheaper, since I can cover around 2 bikes and have some left over for around the same money. Crankskins do come in colors and patterns and this stuff is clear, and I am not sure I want any patterns or colors, I want it to be invisible and let the frame shine through. I can’t say if the quality is better or worse, since I have not done a comparison, but this tape is pretty bomber, and I have never had any issues with it. If a helicopter rotor and a race car going to 200mph use it without any issue is pretty decent in my opinion. I also couldn’t tell what thickness the crankskins were, their site doesn’t mention it. Is it 8mil? Fishboy (a forum person over on the Mojo forum) makes a great tape kit made specific to the Mojo for around $70, not sure, but I would imagine a crankskins entire generic kit would be close to that price?

    With regards to tape issues:
    Sorry to hear you have found the inadequacy of the tape, I have used it for 2.5 years and have had no real issues, my cable housing are Alligator i-Links which are aluminum, so I have metal rubbing on my carbon bike and in the current 11 months and countless miles it doesn’t show any major wear. I did have it doubled up. I have used the lizardskins patches and they are great and can recommend them also. Like I said in the previous answer it takes 200mph race car abuse.

    Some protection is better than no protection, and my Frameskin kits have been protecting bikes for a couple of years now. Custom kits are available for a select range of bikes at present – Mojo, Mojo SL, Anthem X, Trance X, Cannondale Rush and Rize, Pivot Mach 4 and cost about $35 each – This model list grows when I have spare time. Frameskin offers excellent protection… and I expect the generic versions I do may be a good option if other products aren’t living up to your expectations. Preparation is the key to good adhesion, and best results. I’ve done a lot of trialling of various tapes to get one of the best wearing tapes out there. I am yet to wear through it with cable rub.

    Whatever happened to the good ole days where we had steel bikes with quality paint and didn’t need to worry about frame protection. All this fancy CF stuff seems to be just for show.

  • pastajet says:

    Not sure if you noticed, but the main bike in the picture is Titanium. And I have had steel bikes with paint and after a period of time the rear triangle gets chewed up. The tape is just to take care of any bike, whether it’s steel, Ti, Al or CF.


  • Cantitoe Road says:

    Looks like I’m a few years late to this conversation, but we have a product called Shelter. Shelter is an impact absorption medium, which contains 50 layers of a visco-elastomeric material-like a memory foam that absorbs energy before it gets through to the frame. It’s also clear so it doesn’t hide your bike.

    This is a video we shot showing how Shelter works, by using it to protect a fluorescent bulb from hammer impacts:
