YOUR BUILD HIGHLIGHTS
ENDURANCE GEOMETRY
A relaxed riding position, matched with modern features like wide tire clearance allows you to go longer while maintaining the performance edge every Litespeed is known for.
FULLY INTEGRATED
The Arenberg FI also incorporates full housing and wire integration. With a selection of cockpits, fork and bottom bracket options, all cables and housing are neatly tucked within the confines of the bar, fork, and frame, and out of the wind. For those demanding a clean, full aero and fully functional cockpit option, there’s no better value in titanium road.
FULLY CONTROLLED TUBESETS
We maintain the strictest standards to ensure the best ride. That’s why we go to the effort of not only using size-specific tubesets on the Arenberg to ensure a consistent ride experience, every tubeset is tuned and adjusted to meet our strict wall thickness standards. All the performance, with zero excess weight.

|
The height of your bike’s cockpit. Bikes with taller stack height provide a more upright and comfortable riding position. Lower stack height provides a lower and more aggressive riding position.
|
52 | 53.5 | 56.5 | 59 | 62 | 64 |
|
The length of your bike’s cockpit. Bikes with longer reach stretch you forward for a more aggressive riding position. Shorter reach shifts your weight back for a more relaxed riding position.
|
36.5 | 37 | 37.5 | 38 | 38.5 | 39.5 |
|
The distance from the ground to the midpoint of the top tube. It’s good to have adequate clearance between the top tube and the base of your torso to make it easier to ride and come to a stop safely.
|
69.5 | 71.3 | 74.5 | 77.2 | 80.4 | 83.2 |
|
A longer top tube will feel more stretched out. A shorter top tube will feel more compact. Top tube length can help determine fit, but stack and reach are the most reliable measures for modern bikes.
|
50.9 | 52.3 | 54.2 | 55.5 | 57.2 | 59.1 |
|
A steeper (closer to 90°) seat tube angle moves the saddle forward to promote a more aggressive riding position. A slacker angle moves it backward for a more relaxed position. The seat angle of each bike is optimized for its intended riding style.
|
74.5° | 74.0° | 73.5° | 73.5° | 73.25° | 73.0° |
|
Seat tube length is measured from the center of the BB to the top of the seat tube. Seat tube length can help determine bike fit, but it is most useful for determining how long your seatpost needs to be.
|
43 | 45 | 48 | 51 | 54 | 57 |
|
A steeper (closer to 90°) head tube angle provides quick, responsive steering but less stability at high speeds. A slacker angle increases stability but can feel unresponsive at slow speeds. The head angle of each bike is optimized for its intended riding style.
|
70.0° | 70.5° | 72.0° | 72.5° | 72.5° | 72.5° |
|
The length of the head tube will raise and lower a rider’s position on the bike, but stack height is a better measure for this. Head tube length is useful for determining how long your fork steerer needs to be.
|
10.6 | 12 | 14.8 | 17.2 | 20.6 | 22.8 |
|
Increased BB drop lowers your center-of-gravity to improve stability for cornering and rough terrain. Reduced BB drop improves agility and clearance to avoid pedal strikes. The BB drop of each bike is optimized for its intended riding style.
|
7.8 | 7.8 | 7.6 | 7.6 | 7.4 | 7.2 |
|
Measured from the center of BB to the center of the front axle. Lengthening the front center increases stability and can reduce toe overlap. Shortening the front center increases agility and can increase toe overlap.
|
58.1 | 58.7 | 58.8 | 59.6 | 61.1 | 62.7 |
|
Shorter chainstays increase agility and allow riders to be more dynamic with their weight in corners. Longer chainstays increase stability at speed and over rough terrain. The chainstay lengths of each bike are optimized for its intended riding style.
|
42 | 42 | 42 | 42 | 42 | 42 |
|
A shorter wheelbase increases agility and provides quicker handling. A longer wheelbase increases stability at high speeds and over rough terrain. The wheelbase of each bike is optimized for its intended riding style.
|
98.9 | 99.5 | 99.6 | 100.4 | 102 | 103.7 |
|
Fork offset, or fork rake, affects trail. Less fork rake increases trail for slower handling but greater stability. More fork rake decreases trail for faster handling. The fork offset of each bike is optimized for its intended riding style.
|
4.7 | 4.7 | 4.7 | 4.7 | 4.7 | 4.7 |
|
High Trail provides more stability at speed. Low trail provides faster, more agile steering. We optimize Trail for each bike by tuning our fork rakes and head angles to match the bike’s intended riding style.
