Groadinger OMG

custom built | 8-12 week turnaround

Groadinger OMG

from £1995 inc UK Tax

The OMG is our custom 3″ steel MTB

It’s early doors for the OMG but our first fully custom mountain bike offering is coming together.

I know! It’s been a while 😉 regardless! We are still taking a further short pause before the official OMG rollout (gotta love a rollout) to focus on a very special project and some super cool builds on the first frames, so check back here for more pics and info as they emerge.

The plan however, regardless and apart from all of that, is to take orders for the first ‘available to all’ build spots whenever you’re ready, for building around Christmas with delivery in the new year and thereafter on our standard 8 to 12 week waiting. Be warned! This is for bike lovers and holders of the sacred torch of good times. The OMG will be ALL CUSTOM specs. So no plans for stock builds at the moment.

(no-reason food reference rabbit hole starts here) You won’t get an OMG anywhere else! MADE TO ORDER, OFF MENU, DELI-ICIOUSNESS. We will be offering some standard geo and sizing for your delectation, however custom sizing is no extra cost as they will all be made to order, of singular construction and delivered individually with all the love and care that we in the STAYER kitchen can muster. Bring your MTB hopes and dreams to our table and find ambient lighting, sustenance and slightly overwhelming enthusiasm to GO LARGE! from all at STAYERland (run out of food references so end them here).

The idea is that anything you can think to do with 3″ tyre clearance and a no-suss frame can be done with the Groadinger OMG. If you want a big rig for long distance off road touring then we can do that with the OMG. If you want a hardtail with a short wheel base for chopping down the local trail then we can do that with the OMG. So it’s your mountain bike, what are you gonna do? It comes in mullet or 26’er or dropbar with fenders or trail rider, or long distance monster, steel fork feels or carbon for the win, whippy and bouncy, sturdy and looooong with racks, bags and buckets and places to keep your boat or board and so on, and so on.

It doesn’t have to be OTT. It’s just got big tyres. Everything else is TBD.

Let's build your OMG !
