SERGEANT V4 Aluminum
As is the all-too common scenario industry-wide lately, we have received unfavorable updates from suppliers regarding some key components on our bikes, which have been delayed in manufacturing. Despite recent snafus, our frames are essentially on schedule, aside from possible shipping delays. We have taken all of the necessary steps to minimize these delays, but as we’ve just learned with the Mayor v5 and MiddleChild shipments, we are at the mercy of global forces and circumstances beyond anyone's control. See new date above
Due to the extensive lead times being offered by certain components manufacturers, the original specifications/build kits for this bike have been changed. So that we may be able to deliver complete bikes as scheduled, per our shipping updates, certain parts have been swapped out for those with shorter lead times. In each case, we have attempted to make substitutions that do not compromise the integrity of each build. Pricing has changed accordingly.
.
Important: Notwithstanding any change of specifications, pricing on all bikes will have to be adjusted to reflect the increases in the cost of manufacturing and shipping. This is unfortunate, but no manufacturer - large or small - will be unaffected by the strain on the global supply chain. We are doing our absolute best to keep our costs and timelines as close to original estimates as possible.
.
The price changes are effective immediately, and have been applied to all affected bikes, including those on pre-order.
Estimated Delivery – April 30th, 2021 – NEW – Frames are on time. Complete bikes delayed to July 2021 (See latest update above)
Shorter Chainstays, Same Tire Clearance and Slacker HTA
