Introducing new products to Australia is one of the perks we don't take for granted at Chainsmith. We introduced Favero Power meters to Australia the beginning of 2015, built the first Campagnolo Ekar groupset on a Basso Palta, and launched many boutique products such as the beautiful Alpitude Component carbon bottle cages. And now we get to share with you our experience of the first Shimano Dura-Ace Di2 R9200 built on a special edition Wilier OSLR.

Lets look at a few of the conveniences riders of the Dura-Ace 12 speed will experience.

Firstly, the semi wireless system allows the levers to run without wires making a clean and minimal aesthetic not limited to internal cable bar and stems. On a practical level this means efficient installation and maintenance.

Another positive is that we hear Shimano has increased battery consumption by 75% lasting an approximate 1000km's.

When it comes to ergonomics there's a few changes to the shifters. The brake lever is positioned for better reach with potential to improve braking power for riders who've had issue with reach in the past.

Meanwhile the hoods themselves are angled inward replicating principles of recent gravel bars which improve comfort by allowing a relaxed hand/wrist placement. The shift levers are comparatively placed outward and designed to be longer. Changing gears on the drops becomes easier with better reach.

Speaking of off-road cycling, there's echoed influence from the elite MTB scene when it comes to brakes, more precisely the rotors. The new rotors are lighter with an improved cooling system derived from professional MTB. This means during your long and steep descents the rotors will noticeably disperse heat more efficiently and with less risk of overheating or loss of braking performance.

Still focused on the brakes, the callipers themselves are designed with more allowance between the pads. This means less potential rubbing which eliminates disc noise associated with lesser group sets. Better yet, when you're applying more strength in a sprint your wheel has the freedom to flex without the notable friction or brake rub.

When it comes to shifting, the front Derailleur is re-engineered to improve shifting time between cogs. There's over 50% less lag time though we'd argue the lag was never a point for complaint. Regardless it means even crisper and faster shifting compared to an 11 speed predecessor. 

Last but definitely not least, the obvious point of difference is the 12 speed cassette. You'll experience fluid shifting between each cog making gear changes a pleasure as the shift feels seamless in transition.

We look forward to our Shimano Dura-Ace Di2 R9200 pre orders arriving. But in the meantime you may be lucky to see the 12 speed Dura-Ace passing over roads of Sydney this weekend.
