CLUELESS
Clueless? Not sure where to go next? The clueless will help you get lost!
The Clueless has received more updates than any other frame in our range… not because we didn’t like the last one, we loved it, we just wanted to bring it into it’s own category!
Just like the Purple Haze, we didn’t see the need to change the geometry of this bike (don’t change a winning team!). However, we still wanted to update the tire clearance and all-road-ability. The updated Clueless stands out from the crowd thanks to its newly refined details like dropouts, seatpost clamp, the list is long. It took a lot of work to refine the Clueless to where it is and we hope you love it as much as we do!
YOUR OPTIONS
SPECIFICATION
Handmade Sour Bicycles CrMo frame featuring heat treated, multi-butted tubing that’s ED-Coated for rust-proofing.
Our dropouts are designed in-house, in Dresden and have a replaceable derailleur hanger.
The seat clamp is designed in-house and is integrated into the frame. Should it ever fail, the frame can be professionally modified to use a traditional clamp.
