Tui ER1 Road Bike- 105 2x12 - Lightweight Titanium road bike

Finally a great road bike designed for the smaller half of the population. Available in sizes from XXS to Large the Tui ER1 Road bike is fully designed for to be proportional for riders down to 4'8" We customize the crank length, frame size, and stem/handlebar combo to make the perfect fit for each rider.

Tui Titanium Bikes was born from our goal to make sure that everyone can get a great bike that truly fits their unique body and riding style. At Zinn Cycles, we have been building custom bikes for short people including small women and men for over 40 years. We understand that a custom bike is not something that everyone can afford, so we have founded a new brand of non-custom titanium bikes for short people.

Major bike brands tend to focus their efforts to make bikes for the average sized person, since that demographic is going to offer the largest number of potential customers. That range is from about 5’7″ to 6’2″. The further you are outside of that range, the fewer options there are for you. That is where small companies like us can develop great bikes and components to help fit riders who can’t simply walk into a bike shop and find a perfect fitting bike.

When a small rider gets on a Tui titanium road bike, hardtail mountain bike or e-bike sized to them, they immediately express amazement at how comfortable and natural their body feels pedaling it and how effortlessly and intuitively it handles, giving them a feeling of great confidence when cornering. This is no accident; it is the result of my careful and studied understanding of what the human body in general and a small body in particular requires to be properly supported on a bike for optimal pedaling efficiency, comfort, and control. All of my years of experience help me to truly understand what it takes to build bikes for short people.

In an effort to offer a quality lightweight titanium bike for everyone, we offer the Tui Road bikes in sizes XXS, XS, S, M, and L. The S to L sizes are made to order and we try to keep the XXS and XS sizes in stock as much as possible since those are the sizes that are more difficult to find elsewhere. 

Semi-Custom for a perfect fit

Clydesdale bikes use set frame sizes, with fit adjustments tailored to the rider. Rather than building a custom frame, we work from your fit requirements and select from the components we keep in stock.

• Fit adjustments: We customize crank length, stem length and angle, spacer stack, saddle width, and handlebar selection based on your fit.
• Accent colors: You can choose colors for the headset, spacers, and seat binder, plus handlebar tape on builds that use it.
• Wheels and tires: We select a wheelset and tires suited to your type of riding. We offer several tire options; contact us for the current selection.
• Frame Color: Frames come in bare titanium with anodized graphics. You can pay extra to have the bike painted any color you want. Please ask us for pricing on a custom paint job. 

Frame size is the starting point. These adjustments let us tailor the bike’s contact points to you. After you place your order, we’ll send instructions for submitting your measurements or arranging an in-person bike fit.
