Fillet Brazing vs. TIG Welding Frame

Posted on by

Brazing, a lower temperature process than welding, uses a bronze rod to create a fillet–a French word for ribbon–pronounced FILL-it (not fill-LAY). It was previously thought higher welding temperatures would ruin good tubing. We now know because welding is faster, the damaging effect of higher temperature is mitigated by shorter heat duration. While disagreements about the relative merits of lower temperature vs. shorter duration continue, a properly fillet-brazed joint will certainly have greater accident “survivability.” For example, if you run into a tree or parked car, a fillet-brazed joint is less likely to fail. Either joint will withstand decades of normal use.

 

Because the bronze fillet is softer than the steel tubing it joins, a skilled craftsman can sculpt a brazed joint without cutting into the tube. Please note that the quality of this sculpting (or craftsmanship) is highly variable–look for large smooth fillets with compound radii and long feathered edges. Beware of “overbite.” Overbite, a result of hurried or sloppy work, is where part of the steel tube has been carelessly filed away at the edge of the fillet. This creates a stress riser that can lead to frame failure. Unfortunately, overbite is a common flaw found on many fillet brazed frames.

Unavoidable downside of fillet brazing #1: Price.

 

Because fillet brazed construction requires much more time and skill, the price of a properly fillet brazed tandem frame will be $300-$500 higher. If the price differential is lower, inspect the joints carefully before taking delivery. Because of the price, most bicycle customers choose a TIG welded frame.

 

Unavoidable downside of fillet brazing #2: Weight.

 

A filleted joint, like a lugged joint, is slightly heavier than a TIG-welded joint (4oz penalty on a single bike, 12oz penalty on a tandem).

 

Because a properly fillet brazed frame is the ultimate hallmark of a skilled frame builder, the best reason to buy a fillet-brazed frame is because you value the artistry and can appreciate the builder’s skill.

How to Choose a Wonderful Racing Bike

Posted on by

The racing bike is one of the best options to improve physical fitness by long-distance riding and high-speed movement on lines with a smooth finish. Regular driving on a highway or model contributes to the harmonious development of all muscle groups. That is why experienced cyclists are increasingly choosing it. So, how to choose a wonderful racing bike?

 

Above all, let’s consider briefly the differences between road racing models and other types of two-wheelers, including:

 

  • Lightweight frame, wheels, and components
  • Narrow tires
  • The front fork is often made of carbon fiber
  • Without back or front suspension

 

Frames

 

When buying such a bike, future owners have to choose between the frames, made of carbon fiber and aluminum. Most of the aluminum frames excel at driving on a flat surface. However, this option is much cheaper as compared with carbon. Racing bike frame made of carbon fiber exhibit improved resistance to stress and maximum effective cushioning during the transport.

 

Wheels

 

As already mentioned above, the racing bikes are often equipped with narrow high-pressure tires. The surface of the latter contains a minimum quantity of protectors. Wheels that are tailored to these features would provide a low-level friction from the road surface, which contributes to the development of a high speed.

 

Pedals

 

Most of such bikes have no pedals as standard. This is due to the need of suiting the characteristics of riders’ shoes. Competent approach to the choice of the pedals is largely reflected in the comfort of driving and achieving the desired results.

 

Recommendation

 

If you are in need of a racing bike, I would recommend the 700C racing bike. This bike comes with the ultra-light aluminum alloy frame, which is anti-static coated. Thus, it looks nice and is durable for use. And the three aluminum alloy spokes provide high strength and speed improvement. What’s more, the racing 46T crankset with exquisite workmanship keeps fast riding.

 

Summary

 

When choosing the first racing bike, special attention should be paid to the racing bike frames, wheels, and pedals, as all this would affect the future riding experience. And I think the 700C racing bike will be a good option for ordinary sports fans and those who are planning to improve physical fitness and develop all muscle groups by long-distance riding and high-speed movement.

Cyclocross Bike Frame and Its Related Simple Introduction

Posted on by

What is cyclocross?

 

Cyclocross is a discipline that combines both off-road and on-road cycling. Typical cyclocross terrain includes grass, woodland trails, pavement, mud and even sand!

 

Rapidly growing in popularity, cyclocross racing is primarily an autumn/winter sport – with tens of thousands of fans attending races in Northern Europe. The attraction of cyclocross racing is the fast and frantic pace, around a lapped circuit of 2-3km in length.

 

The good news is, you can do cyclocross all year round! A cyclocross bike is incredibly versatile, and can make the perfect commuter, touring bike or do-everything ride.

 

What is unique about a cyclocross bike?

 

At first glance, a cyclocross bike can appear to look like a road bike; however there are many features that make them uniquely different and more suited to the specific purpose of multiple terrains riding.

 

These differences include the tires, frame design, brakes, gears and pedals. Below we only introduce the cyclocross bike frame designs.

 

Cyclocross bike frame design

 

The frame of a cyclocross bike has been adapted from a standard road bike frame, in a number of ways:

 

  • Increased tire clearances on the frame and fork – A cyclocross bike frame have increased clearance for tires on the front and rear of the frameset. This is so that you can use larger volume tires, for increased grip and traction; as well as allowing the wheels to keep turning, even when they are carrying significant quantities of mud or trail debris in the tire tread.

 

  • Frame geometry – Cyclocross bikes often have more relaxed geometry angles, to give them a more upright riding position than a road racing bike. This position helps with shock absorption off-road, but it also allows you to utilize the bike across multi-disciplines, such as touring and commuting.

 

  • Frame material – Many modern high-end road bikes are now made of carbon fiber, due to its light weight and vibration absorbing characteristics. Cyclocross bikes have followed this trend too, with many high end models made of carbon. However, aluminum and steel frames are also still popular; because they provide a lower cost option, and provide a more durable frame if the rider wants to use the bike for touring or commuting.

 

Frame sizing on cyclocross bikes

 

As with all bikes, the sizing of cyclocross bikes is vital to maximizing comfort and performance when you are riding. This is especially important if you are going to be using the bike for long distance touring or winter training as well.

 

 

What else can I use a cyclocross bike for?

 

Cyclocross bikes are not just reserved for use off-road. The relaxed geometry, strong frame, powerful braking and good tire clearance, mean a cyclo-cross bike is highly versatile machine. ‘Cross bikes can easily be used for other disciplines within the sport; such as commuting, winter training, cycle touring and off-road adventures.

 

When you are considering our range of cyclocross bikes, you may want to consider what other uses you may have for the bike; some bikes have mounts for pannier racks and mudguards, as well as more powerful disk brakes that are ideal for touring with heavy loads.
