PAP Wonders...To Buy or To Build?

When it comes to getting a new bike, there are two options you buy a built bike or spec & build one yourself. Almost all cyclists start with a built bike because it is always available. Why not? Go to the bike shop, look for one you like and go home with your new bike.

A "Spec & Build" Bike.

Built bikes. Built bikes are normally built up in such a way to accommodate majority of riders. For road bikes, this would mean compact cranks and an 11-28 cassette. For mountain bikes, cranks would either be triple or double, and paired with a wide range 11-34 cassette. Although, nowadays, mountain bikes spec'ed with single chainrings (or 1x - "one-by") are becoming more popular.

• Drivetrain. These rarely have "straight" groupsets (except for the higher end models). There are always parts from another groupset of the same manufacturer or from a different brand. For example, when manufacturers quoted a bike as having a "Shimano 105", what I got were Shimano 105 shifters, front derailleur and rear derailleur. The crankset is a non-series model from Shimano and the cassette is Shimano Tiagra (one level lower than 105). Because these are not as complex as the shifting mechanisms, these substitutions have hardly any recognizable effect (see our article about mixed groupsets). The brakes are unbranded.
• Wheels and Cockpit. These components are usually supplied in-house - by the frame brand itself. Another possible supplier would be a subsidiary or sister company of the frame manufacturer. For example, when I got my Giant Defy, the wheels and tires are from Giant. The whole cockpit - stem, handlebar, bar tape, seatpost and sadde - are also wholly provided by Giant. Essentially, the whole bike except the drivetrain are produced by Giant.

PAP Wonders...P-E-D-A-L-S!

It's been a while since the last article but I hope this new article will be helpful for those who want to change their current pedals or try new pedals. The pedals are part of the "cockpit" of the bike - the components which connect you to the bike. This category includes the handlebars, saddle, stem and seatpost. Here is a link for an introduction to the cockpit. The pedals' purpose is to let you transfer your power to the crankset, then to the chain, then to the cogs, then to the wheel, and finally, to the ground.

What types of pedals are out there? Pedals fall into two basic categories: Flat pedals and Clipless pedals. Flat pedals are what most people (even non-bikers) know. They are everyone's first pedal and there are several advantages in using them. First, they are the easiest to use and the most confidence-inspiring. Just put your foot on it and pedal. If you lose your balance, you can easily put your foot down on the ground. Second, flat pedals are offered at a wide spectrum of price points from the most affordable to the most expensive. With flat pedals, the cyclist can use any shoe he already has - sneakers, skateboard shoes and others. Clipless pedals, on the other hand, need cycling shoes.

Example of a flat pedal. This particular example has metal studs to improve the shoes grip on the pedal.
