Positive	Very light, damage can be seen immediately,	cheaper than plastic rim, light, true to track, stable under rotational load, easy to mount, sporty look , easy to fill the compressed air from the front	Very stable, easy filling with compressed air from the front	very light	light, stable, good optics, easy filling with compressed air from the front
Negative	expensive, plastic breaks easily, difficult to mount, be careful this rim can break when mounting the tire with a machine , mount tires only by hand! With light shocks while driving the rim quickly begins to egg (unbalance)	Damage to the rim is difficult to detect (hairline cracks), rim edge scratched on curb contact, assembly only possible with small (thin edge) 13 'er nut	relatively heavy, optics, expensive	Warping easily, mounting a new tire is almost impossible as the old tire can rarely be pulled off without destroying the rim (disposable rim), expensive, optics	Mounting only possible with small (thin rim) 13ér nut
Weight:	2.29 KG	2.68 KG	3.12 KG	2.38 KG	2.52 KG
Appearance:	eggging and breaking of the plastic area	Scratching, breaking of the rim inside or warping in case of lateral pressure/pull.	very robust	Wheel warping and egging under lateral pressure	very robust
Important	Danger of fall: rims that egg, show impacts, with hairline cracks and deformations must be replaced immediately, difficult to detect breakage hazard! Especially after accidents and after fast driving over high edges (high curbs, thick roots, etc. ) Here you save in the wrong place! Regularly check the bolting of the rims!
Important	Danger of falling: rims that egg must be replaced, risk of breakage! or risk of loosening the molded components plastic and stamped plate	Danger of falling: rims with blows, hairline cracks and deformations must be replaced immediately, difficult to detect, risk of breakage!	Adapter must be centered and fixed with Loctite, rim runs design not as accurate as, for example, an i2 rim	Rim is more or less a disposable rim and is usually destroyed when mounting a new tire	Rims with hairline cracks must be replaced
