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.

Frame geometry affects bicycle handling and therefore can be quite different between two bicycles of the same fit/size.

So,
if the numbers on the Sizing table are a little confusing and do not compare to your current frame then please fill in the form below (as best you can) and we will get back to you with a custom fit drawing and frame size suggestion in 1-2 working days.

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.

These start at £2500 for a frame set. We only do a couple of these a year, so if you’re patient

and have an exciting idea just get in touch on the contact form below.

The OG PLUS is available in 27.5 and 29er versions – same but different riffs on the idea of a short chainstay drop bar party of a bike that will mean different things for different folks.

So! there are many articles and bits of info to internet search for here – it’s a very deep rabbit hole of a subject and one that we are happy to talk about if you want to ask.

Wheel size is what it’s all about, we aren’t here to tell you what you want, we’ve got options and we’ve got information AND! We also have a telephone so if you feel you want to ask about any of the pros and cons of wheel sizes – or indeed anything STAYER related at all – then we are here for you. Drop us an email or pick up the phone and we will do what we can to help.

Brief pros and cons of 27.5 and 29er wheels

27.5” wheels are smaller in diameter – with equivalent tyre widths – and are therefore a bit more manoeuvrable and get up to speed quicker. 29er wheels are larger in diameter and therefore roll over things with more ease and go further for less effort. The larger 29er also needs more frame to fit in which makes the frame more flexible and therefore slightly less easy for the rider to handle or move around obstacles.

27.5″ wheels are smaller and therefore lighter overall, whereas 29er wheels have a larger area of the tyre in contact with the floor at any one time so give more grip or traction.

In the world of relative size of things a 29er wheel will feel different on an Extra Small bike to how it feels to ride on an Extra Large. There is no rule here, or anywhere tbh, and much of the above pros and cons are so close in comparison that you may not notice the difference. Our advice is that it is worth considering what your use will be, how you want the bike to ride, what size your bike is going to be and then if possible take a test ride – please ask about this if you are on the fence about what to go for.

CNC and design wizard @Hulsroy designed a sick yoke for comfortable clearance for 2.3” rubber and we updated our geo’s with dropper posts and shorter stems in mind.

Available in either 27.5” or 29er wheels sizes and for MTB and wide road drive chains up to 40t up front.

You might be aware that we also hand-build some sweet wheels, in house.

For the Groadinger OG PLUS we recommend either the Gravel / MTB Wide wheelset (COMING SOON!) or the
Gravel Adventure wheelset as carbon options.

Or the GRAVALLOYS
GRAVALLOY WIDES for aluminium
