TECHNOLOGY

SDM RIM TECH
To make strong, durable rims, we add extra layers of carbon to some of the most important parts of your wheelset.

SDM BRAKE TECH

SDM HUB TECH
We’ve built an over-class hubset into our SDM designs. The BladeX SDM hubset is designed to have extra-strong wheel geometry, durability and smoothness…

SDM SPOKE
It might seem like an obvious fact for any road bike, but we’ve seen again and again that thicker spokes make for a stronger and more durable wheel.

Well made, smooth rolling and reasonably light but strong!
I have had only 3 rides on them so far but to this point have noticed they roll well, have no noticeable flex and behave very well in light winds. With only 150km’s on them so far its not a comprehensive test but I am very happy with the product so far. I am 85kg’s and ride undulating terrain. Not a lot of hills right now and never mountains. This is my second pair of BladeX wheels. My first pair , the 2X2, have been reliable, quick and strong. Communication has been very responsive too which is a nice change when dealing with overseas suppliers of components.

Hello, can you build the wheelset with CX-Ray spokes?

Hi Roby,
The default spokes are from Pillar, model 1423 Aero, an very durable and strong choice.
If you prefer lighter spokes like Sapim CX-Ray, you can custom your wheels at: http://i1k.70d.myftpupload.com/custom-your-sdm-handmade-road-bike-wheelset
There are plenty of choices for Spokes, Hubs, and even Rims.

These are not Sapim CX-Ray spokes on these SDM 4×5 wheels correct?

Hi, can you build the wheelset with Chris King hubs?

Sure, Chris King is our builder’s favourite hub, a little pricy but definitely the finest hubset we have built.
