American carbon fibre component manufacturer is updating its rim range. A new rim will show up very soon, and a rim is slightly upgraded.
The current range is composed of 8 different rims, from 4 different depth.
The 1.24, 24mm shallow is an extremely light tubular rim. Its weight is sub 220g.
The 1.38, 2.38, 38C are 41mm deep, and weight between 275g and 410g depending on their version: light tubular or clincher.
The deepest versatile rims are the 1.68, 2.68, 68C, 66mm deep. They weight from 350g to 475g, here again, depending on their version.
Finally, the 112mm deep rim is made for very special events.
Then, a 45mm deep rim is hitting the range. The 1.45 will weight between 300 and 310g, and will come in a convex shape (slightly toroïdal) in order to offer first class aerodynamic properties. This shape is close to the one of the 1.68, and is completely different from we are used to see on the 1.38 which is concave (curved). This new rim should be the most versatile of the range. The 1.38 will still be made, and will be perfect for mountain, for riders who can't afford using the very shallow 1.25 rim.
Some new wheels are to be expected from the japanese manufacturer. Beside the 24mm, the 50mm deep wheels, two other wheels are already UCI approved while they are even not in the Shimano catalog! So a 35mm deep rim with 16 spokes, and a 75mm deep rim with 12 spokes should be tested by pro riders very soon...
