Whenever a new groupset is released by any of the major groupset manufacturers the first thing that comes to a tinkerer's mind is groupset compatibility. Now that both Shimano and Sram are producing 12 speed groupsets, we had to know if they were cross compatible. We had a feeling there were gear ratio's that were more optimal than each brands stand alone systems.
What if you could take Open's UP frameset and pair it with both Shimano and Sram components to deliver the perfect gear rations for both road and gravel riding. We wanted to keep the top speed of a road race bike and still have enough low end to get over any gravel climb.
This is a very special bike crafted with care back in Oct 2017. With a final weight of 7.91 lbs. (3.584kg), this unique hill-climb machine features at its core an AX-lightness Alpha frame paired with THM Scapula Fork.
