Bossi Grit SX | Paul's Custom Build
A dual-purpose do-anything bike
The brief
Paul was looking for a titanium bike which could handle his on-road adventures as well as his off-road. The solution? A Bossi Grit with a twist.
The build
The groupset was based on Paul’s preference for Shimano components, and he wanted to stick with a 2x system (which leans us towards Shimano as well).
The choice to meet his needs was the ever-reliable, gravel-specific GRX Di2 as it let us achieve a wide gearing range. (Plus if you get the chance to go Di2, you take it.)
Now what to do about using the bike on two very different types of terrain? You could just have different tyres for each, sure, and spend time faffing about, transferring tubeless sealant back and forth. A far easier -- and better -- solution: one 700c and one 650b wheelset that can easily be swapped out. The differences in tyre profiles also give the greatest performance for each discipline.
For Paul's road wheels, we went with a lovely carbon set of Bossi RD2s in 40mm with DT Swiss 240 hubs. For the gravel wheels, we custom-built a set with DT Swiss rims and 350 hubs. Excellent performance, great durability, and quick interchangeability!
With that part done, we turned to the contact points. Easton EC70 AX bars offer the lightness and vibration absorption of carbon, and with their 16 degrees of sweep, they’re perfect for gravel use without being too flared for road use. We matched them with an Easton EA70 stem to continue the Easton theme up front.
Finally, a trusty SQ-Lab 612 Active saddle plus some sleek and grippy Fizik Terra Bondcush tape provided extra comfort.
The end result -- a sleek, stealthy beast, ready to tackle multiple surfaces.
