EUC Natural Fit handrims With Super Grip Thumb Strips 25" 6 point tab mount

Description

These shipped with my chair but didn't work for me, so were only on the chair for a few days until different handrims arrived to replace them.  There are a couple of small scratches (see pictures), but otherwise they are like new.
These are the standard size (not the LT), have standard 6-point tab mounts, and are for 25" wheels.  They can be mounted with the thumb strips, or those can be removed and the rims can be mounted closer to the wheels or in their further out position.

Research Evidence of the Benefits of the Natural-Fit Handrim
The research evidence (detailed below) demonstrates that you pay a price with every push on the skinny, round tube standard handrim. The price is less efficiency, more effort, and more fatigue and pain. In contrast, the same research shows that the ergonomic grip of the Natural-Fit improves performance and efficiency with every push:
The Natural-Fit provides a 16% reduction in effort to grip the rim.
You can cover the same ground with less work and less fatigue.
Multiply the effort saved on every push by 2000-3000 - that's the average number of times wheelchair users push on their handrim in a single day.
The Natural-Fit uses the original, larger profile oval. It offers 80% more surface area for gripping than a standard handrim and weighs just 1.5 lbs.
The Natural-Fit LT uses a reduced weight, smaller profile oval. The LT is designed for those looking for a reduction in weight or a smaller gripping surface (for those with smaller hands). The LT is more than 17% lighter than the original Natural-Fit - it weighs just 1.25 lbs (about 5 ounces more than a standard round-tube handrim).
The Natural-Fit is the leading high-performance ergonomic wheelchair handrim on the market. The Natural-Fit enhances performance and efficiency, eliminates pushing on the tire, eases pain in the hands and wrists, and provides greater control when braking.
Ergonomic grip incorporates two components, an oval and a thumb piece that sits between the oval and the wheel rim and reduces effort to grip to the rim. TheNatural-Fit's ergonomic grip makes it possible to cover the same ground with less work and less fatigue.
The oval comes in two sizes: The Natural-Fit and theNatural-Fit LT. The Natural-Fit uses the original, larger profile oval and weighs 19 ounces whereas theNatural-Fit LT uses a reduced weight, smaller profile oval and weighs 15 ounces.
The Super Grip uses an advanced copolymer coating that provides a higher friction surface on the thumb piece (it is similar to a vinyl coating). This creates a grippier propulsion surface.
