The biggest news at the WTB booth was their new i23 KOM rims. Building on the success of their standard i23 rims, that we’ve consistently praised for their outstanding value, the KOM drops a huge amount of weight relative to the standard i23 without sacrificing performance. WTB is claiming that the 26″ version is 408 grams, the 27.5″ is 425 grams, and the 29″ is 448 grams. For comparison, the standard i23 26″ rim is 459 grams, the 27.5 is 495 grams, and the 29″ rim is 530 grams.
KOM i23’s come with the same TCS tubeless bead technology that makes mounting and sealing tubeless tires as painless as possible. They also feature the same 4D spoke drilling to ensure that alloy nipples seat properly in the rim bed and thereby prolonging their lifespan.
Most of the weight savings come from the removal of the internal I-beam structure and the infusion of new alloys to add strength. While WTB is being coy about the alloy they are using, they are claiming scandium-like durability and stiffness. All we know is that enduro riders who have been searching for a tough, light, and wide rim at a price that won’t break the bank have just found what they’re looking for. We expect to get the i23 KOM in during the holidays. MSRP is set for $95.
WTB’s new i25 TCS rims were also on display. Art’s has the new i25 rim in stock now in all three wheel sizes. It offers all the same bang for the buck that the i23 offers but with a bit more width to better support the tire. The weight penalty for this added width is roughly 25-40 grams per rim over the i23. Price on the i25 is $67.95 for all three sizes.
Lastly, WTB has new alloy tubeless valves to shave a bit more rotating weight off of your wheels and add a little anodized bling. Blue, red, and black options will be available soon.
