Seems like the world of Mountain Bikes is finally beyond me.

Not because of illness, a change in life’s circumstances of just loosing interest in pedalling, but this paragraph on the last Cotic thread.

Its a neat idea but I’m interested to know whether it has true, full UDH compatability in the upper/long/29 position – in other words, can you fit a t-type mech and run 29? Does it clear the bottom dropout?

I genuinely have not the first **** clue what this means. And moreover I can’t even muster any enthusiasm to find out what all these new designs are about because it’ll make the square root of **** all difference to my cycling.

Cheerio young people. Old man out.

just ride your bike and have fun is what i say,that is the most important thing (i agree with what you say about the billion different standards nowadays i will add).

UDH is just srams new rear derailier standard, it integrates with their t type mech which are meant to be much tougher

And a bottom dropout is just natural.

Great.

ANOTHER FHECKEN DIFFERENT STANDARD.

Word. 🙂

UDH is universal derailleur hanger. Something we’ve wanted for decades is for different frames from different brands to use the same mech hanger. It caught in and lots of bikes use it now. There’s a greater chance of being able to walk into a shop and walk out £15 later with a mech hanger that works.

If you remove the mech hanger altogether, it just so happens that the remaining frame shape is perfect for mounting SRAM T-Type mechs. They effectively create a clevis around the dropout area of the frame and hold in place with the rear axle.

Or, leave the UDH in place and run any other meh from any manufacturer including SRAM.

It actually seems like a pretty good idea.

I’m with you! Last legitimate MTB ride I went on people were looking at me like I was a different species, no dropper, no motor, front wheel in same postcode as rest of bike lol.

However if the Cotic thread upsets you DO NOT venture into the Italian coffee bean thread, I’m genuinely now questioning whether I actually enjoy my morning cup of aeropress supermarket grind…

Transmission (t-type) is a way of dangling a very expensive bit of consumer electronics off your rear axle… it also has proprietary lock-in as only one brand can sell you the component that interfaces with your bike in this way… despite you owning the bike…  helping keep the prices high and bringing you back to the brand when you need a new one… think of the daft brand specific charging cables that the EU is helping us escape from… it’s a bit like that. All you really need to know, is that you can still use a normal cable pull rear mech from any brand, that mount in the normal way, using a hanger (UDH) you can buy anywhere, so there is a win for more affordable no-nonsense biking.

If your having fun then just go out and enjoy the trails .

For as long as I can remember the hype and trends are there mainly for one thing and that’s to get us to dig deep in our pockets just to be on trend.

Some will benefit from the constant changes. Most won’t notice the difference and for others it will be a placebo effect.

So there are a big group on this thread that think we should be riding 26 inch wheel rigid bikes with rim brakes and quill stems in one inch head tubes

As the owner and occasional rider of Cotic frame #165, I’ve let all this new stuff pass me by.

I don’t know or care about every latest development and I never ride anything until it’s in the 40% discount zone.

I still know that UDH is a great idea that was well overdue. I’ve got 2 bikes with it and I don’t have to stock up on hangers for each bike.

Would that be a metric or imperial sized stake sir?

Oh no, I’m not that much of a Luddite. I’ve got a dropper on my gravel bike! I’d just rather spend my bike time riding it rather than pondering if the value of marginal gains for me, and probably not so marginal gains for component manufacturers.

Given the last few years of wheel size and hub spacing standards changing UDH is comparatively simple, it’s just a universal hanger standard. Long overdue IMO – I’ve got a spares box full of assorted hangers for frames I’ve had over the years.

The ‘Bike Industry’ seemed to work out about a decade and a half ago that it could come up with any number of needless enhancements to force the rider into buying a whole complete new bike, at an ever increasing inflated price. This is not an aspect that all of us enjoy. I had just as much fun years ago riding cobbled together custom built bikes from whatever best frame you could find and a selection of your favourite parts, it was never hard to build something that worked just fine. Nowadays were supposed to buy into some consumerist market driven fantasy, which the buyer knows will probably be made obsolete in a few seasons time anyway.

UDH has been here for ages. My frame came with it unknowingly in 2022. For those moaning about it, it comes with a standard hanger mount which fits your old-fashioned derailleurs. If you want to use T-type (makes a lot of sense, the electronics, less so) then you remove the hanger and fit the derailleur.

@tthew The competition to sell us more and more stuff is not always to improve our experience but to grow market share for the dominant companies. Like you, I despair at the different “standards” and latest inventions – the FGF clutch chainring thing last week was the latest example.  I’ve opted out of the arms race, I had the chance earlier this year to perhaps spend quite a bit of money on a new bike, I couldn’t bring myself to do it! The tuning (tokens, shok wiz etc) the maintenance, all the bearings and my preferred riding which is natural bridleways and countryside appreciation made me think long and hard. I’ve bought a rigid fatbike with only a dropper post as change of spec. I love the simplicity and reliability and I can now scan technical articles that talk about “cockpits”, “mid-stroke” and “poppy” without having to concentrate. It makes my MTB experience a lot more simple, tthew, don’t leave the scene just ignore most of it, treat it as tinnitus!

To be honest with you I’m still not 100% sure what Boost is all about, I thought it was just wider rear axle spacing but then I see stuff about Boost cranks which totally throws me.

My crux has UDH bought a spare hanger when I picked the bike up reasonably priced and not silly money like some brands charge. It doesn’t mean you have to run SRAM mechs, my Crux is currently running 12 speed Shimano GRX

I see stuff about Boost cranks which totally throws me

Wider rear axle/hub means that the chainline is moved outwards. To match this chainsets moved the chainline outwards as well… which made it easier to build more tyre clearance into frames.

The new chainlines are the one bit of the changing to boost drama that I appreciate as useful. Old hubs gathering dust less so.

I thought boost was something to do with the front axle!

Am with the op, even though I quite like researching new gadgets and kit. But find the different “standards” baffling and boring so I’ve checked out of buying any bike stuff other than the consumables.

whoa

I googled the UDH which seemes like a great idea and the second hit I got was this on Aliexpress!!!

Is it wrong to want one?

For those of you that mentioned it, no I’m not stopping cycling, just means that I’ll be spending less on kit in future as I won’t be hankering after new stuff that is incompatible with my bikes.  

Right, I’m off to fit the new single speed drive train that arrived this morning, at less cost than that that Ali Express Ingrid derailleur. 🙂 

I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary. It’ll happen to you!

Well, of all the things to be annoyed about… UDH is an answer to the thing you dislike :0)

Agree with OP. What I like about bikes is their simplicity and efficiency. Something you can fix and fiddle with yourself.
It’s a cheap and affordable way to enjoy the countryside. Good for your physical and mental health.
That’s it.

This may be a stupid question but are UDH hangers universal?
If i buy any manufacturers UDH will it fit.

I don’t change my bikes much,so most of mine are now racing towards obsolete.

I love them to bits and after years of tweaks and upgrades they are (for me) a perfect fit.

It’s also ( I think) quite cool how unique they are and nobody else has bikes like them  🙂

I consider myself a sceptic rather than a luddite, having stepped off the upgrade treadmill many years ago. Although aware of UDHs I’d paid them no attention because they simply don’t apply to my old bikes (and won’t until the latter break).

So it was with a weary heart I decided to have a look on the back of this thread. Actually, sounds like a good idea – and seems like it’ll standardise through axle threads and dimensions.

New ideas, new concepts, new marketing… I love it!

Yes, some of it will fall by the wayside but ongoing tinkering adds up over time to give us real progress. The bikes we ride now are so much better than those of just ten or fifteen years ago. I don’t know many who will think, “Ah a new standard… I must rush out and buy it”. Change happens when we decide to buy a new bike. I’ve been a bit spendy this year (can’t take it with you) and a couple of the new bikes I’ve bought came with the new “Transmission”  mech, cassette and chain. I was already on electronic shifting (ace) but the Transmission stuff has made things even better: virtually no chain noise over the roughest ground and extremely precise shifts… every time. No mech hanger to ever damage, and spares are available to repair a damaged mech. And this step to a “Transmission” set-up has been allowed by the UDH standard. And the UDH standard has to be better even if you choose to run cable operated stuff.

That said, I think I might go out on the steel hardtail later. Cable operated gears and all 🙂

Great.

ANOTHER FHECKEN DIFFERENT STANDARD.

at the stake.

That’s been out at least six months so is hardly new, hopefully you’ve been out riding all that time so missed it because of that, which is what it’s all about, riding first, new kit later

Wow

My pal asked my opinion on what sus fork to buy to replace his knackered one (bike is a few years old), I responded with the following queries about his bike:

• What size of steerer tube?
• What type of brake mount?
• What type and length of front wheel axle?
• What fork offset?
• What travel?
• What size of stanchions would he like?
• What size wheel?
• Air or coil?
• Does he want a remote lockout?
• Budget?
• Colour?

He wasn’t aware there was so many options.

OP, I feel this way whenever anyone talks about suspension tech. Compression rate this, mid stroke that.. I get that it’s important like bike fit and geometry are important but I can’t help it, my eyes glaze over and I realise why all my bikes are rigid. Just CBA with the faff of that stuff any more.

PS UDH, a standard .. haha, we wish. Wait a year or 2.

to be fair only the ones in bold would be things he needs to tell you. Everything else he wants your opinion on what is best.

I genuinely have not the first **** clue what this means.

It’s only important if you’re more interested in shopping than riding. Otherwise it only becomes an issue when the bike you ride ceases to serve a purpose for you.

I don’t need to know what the latest stanards/gismos/angles are becuase I’ve got a bike so I’m not shopping for a bike.

Should it vanish, explode or disintegrate I’ll shop for another, but in all likelihood a whole bunch of other TLAs will have been and gone by then so no need to know anything about this weeks ones
