Double skinned in Big Apple 2.35 29

Double skinned these liners inside a 29 Big Apple 2.35 rear due to thorns. Stuck them together with thin double sided adhesive tape to hold them in together evenly during installation. Running BigBen 2on front with GreenGuard. The Apple needed more protection being on a norco vlt r2 ebike rear. Changing the rear is not quickeasy.
High speed no problem. Top speed of 57.7 kph downhill into a bend stable.
Make sure you cut overlap for better balancestability at speed. You can keep the excess in your spares kit as a worse case emergency sleeve. Installed just one initially leaving overlap and bike stability was impacted negatively above 40kph. Hence cut them
Apart from that initial learning curve they've proven to be bullet proof onoff road.

I use these in mountain bike tires, both knobbies and smoother trail tires, the inconvenience of flats is greatly reduced and on a plus or fat bike the added weight is negligible.

No more flats...yet

Western was easy to order from, and Mr. Tuffy has proven its worth. I installed them myself inside Kenda tires on my RAD City Power Bike. I watched a video first, and because the Kenda tire was bigger than that shown in the video, the install was easier than I expected - smooth and complete. Up until Mr. Tuffy, I'd experienced a front flat and two rear flats since purchasing the RAD in late August 2018. Mr. Tuffy does seem to have slowed down the speed a tad, but there have been no more flats, the ride feels more secure, and that's riding on gritty, winter crud in the bike lanes where the flats occurred. Western shipped Mr. Tuffy sooner than I anticipated. I bought a set for my wife's RAD City too, but because she hasn't had a flat yet, she didn't want me to install them. One more thing. I'm 74 years-young, and if I can install Mr. Tuffy...well, maybe you can too.
