The Original Gravster PLUS
The OG PLUS is our 2nd gen, mk2, updated super short chain stay, fat tyre drop bar bike.
Our OG gravel bike was always a bit ahead of the curve, before gravel was invented some might say, made for CX style riding on 650b wheel and the fast, rooty single track around our Epping Forest HQ BUT! the times they are a changing and as a result our jazzed stoker, positivity monitor and official voice inside our head shouted Go Large!
So we did.
With more tyre and more MTB, more mullet and more shreds we did a few tweaks and now the OG PLUS is where it’s at – that’s a FACT.
The OG PLUS is a frame to take advantage of the mullet, mix and match, mountain bike drive chain and road bike shifter component options that make a proper monster cross machine possible. It’s a gravalicious shred sled to get you out of bed and a 100% Bona fide rad about responsive dirt drop MTB force of cycling nature.
The selections below allow you to customise your OG PLUS frame / frameset / rolling chassis and some components.

The OG PLUS 27.5” is as a dirt drop trail bike
and/or
the perfect small-frame adventure rig.
The smaller wheel diameter 27.5” option is super short at 405mm and on a large bike and will feel very manoeuvrable. For those looking for a drop bar trail bike with a fun vibe and great handling the OG PLUS 27.5” is the one.
The geo is slack enough, and tyre clearance big enough, to make bike packing a go making this the preferred wheel choice if you are after a smaller wheeled adventure rig that can also handle the gnar on an unloaded rad-about with ease and grace.

The OG PLUS 29er is as a drop bar adventure bike
and
in the larger sizes more like a cyclo-cross bike with a mountain bike tyre.
The 29er version, although still short of wheelbase at 425mm, could be the adventurer of your dreams if you are looking for a multi day bike packer rig for hauling on a more tech terrain
but could also be the short wheelbase 29er dirt drop of your dreams if you so inclined, effectively being a UG with more tyre clearance and dropper post geo and routing as standard.

We have tried to set up the sizes to cover most people,
however! everyone is different.
So if you need custom sizing that can be arranged. We build everything in house after all.
What we’ll be needing from you:
preferably from Bike Fit data (e.g. from a bike fitter like Soigneur)
but we are also happy to use fit information – contact points – from a bicycle you are perfectly comfortable on already.
As always, if you’re unsure about anything say the word and we can help you figure it out.
and have an exciting idea just get in touch on the contact form below.Check out our CUSTOM DEEP DIVE page for full custom inspo.
