Cervelo began life way back in 1995, co-founded by Gerard Vroomen and Phil White. It didn’t take long before their school basement project expanded significantly, quickly establishing a reputation for cutting edge bike designs. Ultimately, Cervelo bikes would take athletes to victory at the Tour de France, Olympic Games and Ironman Triathlon. This isn’t an in-depth history lesson, but sometime in 2011, Cervelo saw a change of ownership. One thing remains the same, Cervelo’s road and time trial / triathlon bikes remain a force in aerodynamic efficiency and high performance and have a huge and loyal following the world over.
Cervelo is bringing their concept of speed to gravel cycling – “A new breed of rider is emerging – one who loves the freedom and exploration that gravel culture was founded upon but who has a hunger to ride wild, to go full bore, and to explore not just geography but personal limits. This frontier requires a new kind of gravel machine, one engineered not to roam the trails, but to slay them.” – Cervelo
Cervelo Áspero Gravel Bike
Key features include:
- Speed – Stripped down racing frame outperforms traditionally over-built hauling frames.
- Handling – With our 2-position adjustable front dropout, called the TrailMixer, Áspero adapts to ensure that various wheel and tire combinations work in harmony with the design geometry for optimum handling.
- Versatility – Fits a wide range of tire sizes both 700+650.
- Tire Clearance – 3 most common tire sizes: 700×33, 700×40, 650×47
- Bento mount, 3rd bottle, Downtube protector
- Dropper compatibility
- Removable front derailleur mount
- Threaded axles
- Single bend cable routing
- Internal cable routing
- Dropped seat stays
- “TrailMixer” offering two positions on the fork dropout
- Downtube cable guide
- Dropped chainstays to keep the wheelbase short
Áspero Tyre Clearance
We engineered the bike to fit most 700×42 or 650bx49 tire/wheel combos, comfortably. Of course, there are variables – rim width, tire casing / tread depth – which will affect final clearance. IMPORTANT NOTE – We always recommend there to be 4mm of clearance around whichever tire/wheel combo is installed on the bike.
- 700c allows for a wheel/tire combo that measures up to 44mm (=52-8) at the widest point
- 650b allows for a wheel/tire combo that measures up to 49mm (=57-8) at the widest point
Áspero Trail 101
Education Point #1
- You can get the same optimized trail with two different sized tires on 700C
- Basic Rule (For 700 only): Small(Low Volume) tires=rearward, Big (High Volume) tires=forward
- Forward position=decreased trail=faster handling
- Rearward position=increased trail=slower handling
Áspero Trail 102
Education Point #2
The 650B wheel was historically designed to mimic the outside diameter of a 700 wheel with a low volume tire, to give big tire benefits without affecting the handling.
Knowing this, when deciding on forward or rearward positioning for a high volume tire on a 650B wheel can be compared closely to a low volume tire on a 700 wheel.
Simple Example: A 33mm tire on a 700 wheel and a 51mm tire on a 650B wheel both have an outside diameter of 677+/-2 mm. So the in effect, both of these setups could be run in the rearward position to get you an optimal trail of 62mm.
