For your mixed route adventures. Comfortable for long rides and with the right mix of stability and agility for tackling both road and trail. Room for up to 700x50mm tires (with gravel cranks and 1x).
If you are looking for a bit more road oriented bike, I can build you a "Speed Gravel" model with some geometry adjustments for a little more agility.
If you routes are dirty and rougher, I can build you an "Off-Grid Gravel" bike with an Enve Adventure fork or a suspension fork, room for up to 29x2.1" tires and added stability for more trail use.


Caletti bikes are built one at a time by John Caletti in Santa Cruz, California—resulting in uncompromising quality and a truly tailor-made balance of fit, function, and style.

Perhaps you know what frame Reach or top tube length you like and can select from the standard sizes. For a more detailed fit many of our customers will work with a fitter and get on an adjustable sizing bike/machine and/or try various stems to feel out different setups to find their sweet spot. You and your fitter can send this fit data in and John mock up a standard frame design for you, or design a custom geometry for the ultimate in fit and handling.
Titanium frames are made primarily of Grade 9 Titanium, which is 3AL/2.5V, cold worked and stress relieved. Butted Titanium tubing is available as an upgrade option on most bikes. Steel bikes use a variety of high strength and light weight butted and heat treated tubing from various sources. In either case, John selects tubing for the rider based on their height, weight and desired ride feel to provide a responsive and comfortable frame.
Road bikes are the most agile and quick feeling in their steering due to the shorter wheelbase, steeper head angle and shorter chainstays. They are a good selection if your riding stays on the pavement and you enjoy the fast and light handling characteristics they offer. A Gravel bike has greater stability to provide a more well-mannered character through bad pavement or dirt and gravel tracks. The Gravel bike has longer wheelbase, slacker head angle, more fork offset, and longer chainstays. Where the Road bike is limited to smaller tires, the Gravel bike works well with 35-50mm tires. The Adventure Road sits between the Road and Gravel designs, in geometry and handling. The handling is a little more stable than a Road bike, but more agile than the Gravel bike. It excels on bumpy roads, long rides, and when you want to do explore some dirt roads as part of your journey. It works well with tires up to 38mm wide. If you are feeling a bit timid on descents moving to a more stable bike will help you relax. If you like to go really fast, the more stable bike might bring your speed up even higher as it doesn't get pushed around as much by bumps and wind.
Titanium is a bit lighter and smoother riding than steel. With our standard straight-gauge titanium tubing, the added wall thickness is quite dent-resistant. The fatigue life of Titanium is longer than steel. Titanium is highly resistant to corrosion and does not rust - which is of particular benefit to certain heavy sweat-ers who might find sweat to cause rust on their steel bike top tubes. Due to it's corrosion-resistance it does not need to be painted which makes it possible for us to anodize graphics on it and it's lower in cost to refinish down the road when you want to refresh your frame. If your budget allows it, Titanium is a fantastic material. Steel also has a great ride feel and durability, and while it weighs a little more, the cost is lower than Titanium.
