Giant 2018 Road Bikes – Range Preview

Giant has given us a sneak preview of what's coming from the world's biggest bicycle manufacturer in 2018. We attended the Australian Dealer launch and were provided with 'early release' model details, specifications and prices.

Here is a preview of the 2018 Road Performance range featuring a number of improvements across the board including more disc options for the mainstay TCR range, tubeless wheelsets for the majority of the range, tweaks to the ever popular Defy range and a new gravel grinder/adventure bike in the form of the ToughRoad GX.

TCR Disc Range

The TCR Disc range first introduced in 2017 has expanded for 2018 with disc options doubling to six offerings. It's perfect timing given Cycling Australia's announcement last week that allows the use of disc brakes at club, state, and non-UCI championship level. The TCR Disc range is available across three series: TCR Advanced SL Disc, TCR Advanced Pro Disc and TCR Advanced Disc.

The redesigned fork introduced last season carries over and features the same thru-axle design which when combined with Giant's OverDrive 2 steerer tube (1 1/4in instead of the industry standard 1 1/8in tube diameter) and MegaDrive downtube is claimed to sharpen up handling and improve cornering ability.

The TCR Advanced SL Disc and TCR Advanced Pro Disc models also come equipped with Giant’s updated carbon SLR Disc WheelSystem and score Gavia Race tubeless rubber throughout the range, boosting efficiency, comfort, and control.

The range includes:

TCR Advanced SL 0 Disc – $10,200
