I mounted the Panaracer RiBMo  26″X 1.50″ on a set of Ryno Lite rims with Deore hubs. I got the folding version and didn’t require a set of tire irons to get them on the rims. Sweet. I had so many flats with the previous set of rubber that it was time for a change.

First things first. RiBMo stands for “ride bicycle more” as clearly stated on the sidewall. It’s not some Japanese technical acronym to describe the technology invested in the tire as you would have thought. From a marketing stand point, it’s just weird.

The first thing that strikes out at you is the shape of the contact patch. The center, or the rib? Is literally two CM wide. This creates much less rolling resistance compared to a comparable slick.

The RiBMo’s unique shape is nearly a complete slick with mild siping similar to that of motorcycle slicks. The rest of the tread doesn’t even make contact with the road surface until the tire has to absorb a bump, or your carving in to a turn. The RiBMo’s are nearly silent for such a wide tire.

Not to jinx myself but I have never had a flat. It must be Panaracer’s new “protex” lining. According to their website here , the Protex is 3x time stronger that existing Kevlar technologies. I have about 3500-4000 km on these tire now, they show very little wear.

Considering that I have taken these tires off roading on too many occasions, driven through glass littered construction sites, broken concrete, curbs, drops you name it. They have taken a beating. I’m a heavier rider at 200 pounds, and usually commute with another 20 or so pounds in the pannier.I run them at 80psi, which is the max rating according to the sidewall. I can really tell the difference if they are running low, even at 70 PSI you don’t get the full feeling of acceleration they are capable of, but the ride softens up considerably.

How to describe the feel of the tire. It pretty subjective, but all I can say is it feel almost like riding on a very stiff foam. Panaracer calls this the “mile cruncher compound”. They claim it is more durable than their competitors hard casing tire without the harsh ride. It’s hard to tell if i’ve worn any flat spots in them from emergency braking.

My only concern is how long the center rib will stay pronounced. After so many kilometers the rear tire only appears slightly more worn that the front.

In Canada these tires retail for well over 60$ a piece. Pricey considering the dollar has been nearly at par for a couple of years now. US pricing varies from  33$ at Jenson USA, to 42$ and up at REI and other cycling specialty shops.

All in all I can with certainty that I love these tire. The puncture resistance and low rolling resistance has me sold. They weigh in at a modest 440 grams even less in the skinnier version which makes them easy to spin up.  At 4000km they show no signs of throwing in the towel and I anticipate getting at least two full seasons of use out of the pair.
