With the unveiling of Di2 technology a little over 5yrs ago now, Shimano had made the single biggest advance in bicycle technology for quite some time; offering consistent, blazingly fast and precise shifting at the click of a button.
In the ensuing years it has proven to be as reliable as it is effective – a true game changer, and, as luck would have it, the perfect accompaniment for a flagship Day One and the Alfine internal hub gear. Say goodbye to derailleur/cable adjustments and misaligned gears. Say hello to a sealed, weather- proof drivetrain, smooth and silent gear changes (whether pedalling, coasting or at a complete stop) and seriously low maintenance (a battery recharge once or twice a year for most cyclists and a hub service once every 2yrs/5,000km).
With fully internal Di2 routing and a seatpost-mounted battery to boot (charged through a Mini-USB junction at the handlebars), we think we've created the ultimate urban road bike that could easily be used for anything from year-round commuting, to light touring to Cyclo-cross or casual road riding.
Regarded by many as the best all-round performance tubeset offered by Birmingham-based Reynolds, 853 tubing offers uncompromising performance and superb ride quality alongside an excellent strength-to-weight ratio, thanks largely to its heat-treatment process. The resultant boost in tensile strength (i.e. stronger for the same area of metal) means Reynolds are able to draw thinner walled tubes (down to 0.5mm thick in places), without any loss of structural integrity.
Generous clearances and eyelets for full-length mudguards and front and rear racks mean the Day One morphs quickly and effortlessly into an all-weather load carrier. Tour and expedition ready!
To help maintain the super clean lines of the Day One we've routed all the Di2 wires internally and cleverly secured the battery in the seatpost (charged via a USB access port on the handlebar gear indicator).
We've opted for Shimano's BB86 Press-Fit bottom bracket shell to give the little bit of extra clearance we needed to enable routing of Di2 wires over the bottom bracket. There's also a nice added bonus of having the bearings spaced further apart, helping to spread the load and prolong bearing life.
