According to popular belief, one is never more than six feet away from a Giant employee in Taiwan. Similarly, a Giant-made bicycle is never too far away, highlighting the vastness of its manufacturing influence. In fact, the bike you're currently riding is most likely influenced by Giant as well. Do you notice the sloping top tube and small main triangle? That's because of the "compact" geometry invented by the late Mike Burrows in the mid-90s, and popularized by the Spanish team ONCE in their iconic bumblebee colors.
The Giant TCR, released in 1997, played a significant role in shaping the sport of cycling. Its innovative Total Compact Racing geometry quickly replaced traditional horizontal top tubes, becoming a popular choice for both manufacturers and riders. With a compact design, fewer frame sizes were needed, making it easier for riders to find the perfect fit. Additionally, its lightweight and stiffer construction offered enhanced performance.
According to Giant the key differences between the Giant TCR Advanced Pro and the Giant Propel involve a 10% weight reduction, increased tire clearance to 33mm, and enhanced compliance. These changes solidify the TCR's position as the lightest and most comfortable race bike option, while also featuring expected internal cable routing.
Materials and construction methods may vary throughout the range, with all bikes featuring neatly hidden cables and hoses. The stem also has a recess to facilitate stem swaps and bike transportation, while all frames maintain the same shape. However, the Advanced SL stands out with its use of the highest-grade carbon composite, unlike the lower two tiers which use three bonded pieces for the front triangle. This one-piece construction results in lower weight, less material, and increased stiffness.
