Reynolds 853

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.

Rack & Mudguard Ready

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!

Seatpost Battery

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).

Shimano BB86 Press-Fit

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.
