The Mad Fiber carbon clinchers were a great choice for the bike course.  While not the most aerodynamic wheelset available, at 1285 grams for the pair, it was a perfect balance between great aerodynamics and weight… just what I was looking for.

Out of transition, I set the bike up on the big ring and 17th tooth as the first riser was at least .5 mile into the ride.  PSI was set at around 90 (front) and 100 (rear) as it was rainy and quite wet out on the course.


Though I didn’t mind the rain, the bike showed just how muddy it got out on the course.  The tape near the seatpost is electrical tape where two gels were mounted onto the top-tube.  The rear saddle bag carried two spare tubes with valve extenders as well as two CO2’s and a tire lever.


I will be making a video that shows how my water bottle cage was mounted.  I used a combination of the X-Lab BTA mount (aluminum) as well as the integrated Cervelo/3T Aduro holes.  The shiny inserts are shims to prevent the aerobar from rotating as it doesn’t seem tolerances were quite right.

The Garmin mount is set on top of a 5mm steerer spacer and secured by a countersunk 4mm bolt.  While it doesn’t “lock”, it’s perfectly placed BTA and is easily read while in the aero position.


The helmet of choice was the Kask Bambino (no shield).  Even though I brought a ventilated option (Casco SpeedAiro), the Kask is one of the better aerodynamic helmets, especially for riders such as myself that tend to move their head around quite a bit.  Without the high temperatures on race day, I opted for ‘aero’ instead of ‘vented’.

Overall, there wasn’t anything I’d go back and change as I was happy with my equipment choices.  I did receive a Cobb Gen2 saddle two days before the race, but opted not to mount it as it was too close to race day.  If you’ve got any questions, feel free to leave a comment below, or drop me a line.

  • Also, it appears you are running the x-lo bar. Can you discuss this choice a bit opposed to maybe removing some spacers and just using the regular low bar? -TG

      Good question and observation. The bar however is the standard set-up, not the x-lo. I went the spacer route instead of the High-V because the races and riding in general around here tend to be a bit hillier than AZ. I prefer climbing on the bull-horns once it gets to 3-4% and higher, so the higher base-bar position for me feels better.

    Andres I see some good stats here, but what about your height and weight? Would also take inseam if you had it. -TG

    • andres says:


      I’m 6’2″ and was between 180-185 on race-day. My inseam is probably in the mid 35″, so I’m one of those long-leg, short-torso riders.
