The new Stayer Cycles Groadinger UG (Ultra Grav) builds on the Original Groadinger design, but offers a less race-focused riding position and is better suited to extra long days in the saddle. The TIG welded, Columbus Zona T45 mix steel frame is compatible with both 1x and 2x drivetrains, unlike the original Goradinger with was 1x-specific. The frame also features flat mount brakes, and since they’re handmade in London, Stayer can customize the frame to your liking with other features and standards. It’s designed around 142x12mm stainless thru-axle dropouts and a T47 bottom bracket, and when paired with the Ritchey Adventure Fork, can easily clear 650b x 2.1″ tires. There are two bottle cage mounts in the main triangle, as well as a third under the downtube, with the option for additional fender mounts and even rack mounts.
Stayer worked with Tim from Soigneur Bike Fitting to hone in on the Groadinger UG’s geometry to prioritize all-day comfort and different frame sizes to cover most people. It’s available in five different sizes, but if the numbers don’t work for you, Stayer suggests reaching out to work on something custom. A quick look at the geometry chart puts the Groadinger UG in a similar category as the All City Gorilla Monsoon, with a slightly shorter wheelbase, quick handling front end, and short chain stays. Overall, it looks like it would be a fun bike to zip around gravel roads on and totally capable for bikepacking as well. Find geometry and sizing details below.
Right now, Stayer is offering two purchasing options for the Groadinger UG: as a frame and fork or a rolling chassis. Both options include your choice of finish and painted decals, a Whiskey RD+ or Ritchey Adventure Fork, Hope headset, Wheels Manufacturing bottom bracket, Hope seatpost collar, and your choice of rear derailleur hanger. The rolling chassis option gets all of the above, plus a 650b Stayer gravel wheelset on your choice of DT 350 or Hope hubs for centrelock or 6-bolt disc with tubeless tape and valves installed. The frame and fork option costs £1,650 (~$2,050 USD) and the rolling chassis costs £2,550 (~$3,165 USD). Since the Groadinger frames are made in small batches, the best way to ensure you get one is by making a pre-order, which has an expected delivery date of sometime in September. Otherwise, if Stayer Cycles has what you want in stock they’ll paint it for you and ship it your way as soon as possible.
