Taking years of experience designing, building and riding all types of bikes on varied terrain, I created the Scrambler. The Scrambler is a flat-bar-specific Gravel bike. The top tube is longer to match the flat bar and shorter stem. The head angle is reduced from a drop bar Gravel bike to have the right level of stability for this setup. It’s not as “slack” as a mountain bike, so it can retain a favorable weight distribution for solid handling on road descents and be nimble in the tight and twisty low angle terrain. If your routes are a mixed ramble of road and trail, but heavy on the dirt, the Scrambler may be for you. The flat bar is easy on the back and neck, great for hops and drops, and leaves plenty of room for a wide bar bag on your bikepack trips.
Fits up to 700 x 50mm tires. Dropper post routing and a third bottle are available options. Fork has extra cage mounts.
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.
Configure your bike to suit you—your body, your riding, and your style. Every detail is considered to create a bike that is right for you.
From a subtle polished titanium logo to color anodization, graphics, or paint - the choice is yours. Enjoy.

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.
