Computer Fluid Dynamics Simulation:

The Venn 507 rims were made to perform especially well in aerodynamics with 25mm wide tyres, yet without the need to have a deeper profile.

As a result of extensive CFD (Computational Fluid Dynamics) work, you will notice that the Venn 507 were not designed with the currently popular “U” shape. The current popular “U” shape rims are not very favourable in aerodynamics performance with tyres that inflate beyond 24mm.

With the 25mm wide tyres being the preference for most riders now, a “U” shape profile rims has to be deeper than 50mm to remain competitive in aerodynamics performance. Thus with such an increase in depth and width, the rim weight will go up significantly.


All our wheels are hand built in-house and tailor to your individual needs. Should you not see something you want here, that's because we can't possibly list everything. Drop us a message at Facebook or email us at , we will be glad to build a pair just for you.
