he V-shape design is coming directly from the initial founder of outward-bound and massively enhanced rim flanges on mountain bike wheels. The shape has been tested and approved in uncounted series of experience and now features grip grooves to generate ultimate tire interlinking. It is 25 % stiffer and boasts with the performance of of a rim that actually is 2 mm wider looking at the tire width and the adhesion 

A light hub with a heavy rim? No thanks!

The overall weight of a wheelsets tells you no more than one half of the story; the MOI is a lot more telling.

This is because it reflects how far the weight of the overall design is placed away from the hub and thus how much it slows you down.

Comparison with an the ­identical overall weight:

  1. Low inertia – the weight is ­close to the hub and does not constantly have to be accelerated.
  2. High inertia – the weight is ­closer to the rim and thus leads to a higher effort.

Real Weight Indication

That is because the value stated refers to the actual weight of the wheelset, as it is mounted. Further washers are not necessary.

Sealing milk advice:

Using sealing milk that contains ammonia causes corrosion damage to your spoke nipples and rims. Make sure to use only ammonia-free sealing milk like e*thirteen Tire Plasma or Continental RevoSealant with your Syntace products.
