For reasons that escape me now I have a threaded fork in the shed. Again, It took me 5 minutes of riding bicycles for leisure to realise that “standards” is a meaningless word in a hobby that is driven by marketing and discretionary spending. What’s taking you so long?
The questions really are:
Why am I mean to like it?
What other pastime should I and legometeorology since the message seems pretty clearly to sod off if we don't like it?
And its not only pastimes... I don't like needless waste or built in obsolescence in anything.
Ok, cant wait…..why is it always the free members..
I can answer for me because I do not do subscriptions.
It's a life rule like I don't gamble
Peak torque makes some valid points
MapDec made some counter-points.
I think it’s time to maybe re think having mechs dangling down, I recall seeing a configuration with a rear mech sort of between the stays out of harm’s way.
I don't really kill rear mechs but I do like the idea of maybe a Classified 2-speed rear hub combined with a smaller cassette and short cage rear mech.

Like the Nicolai Nucleon 16 with Supre-drive. Same issues as gearbox bikes, in that the frame has to be designed around a single, specific drivetrain. These drivetrains will always be a niche option for that reason - the rear derailleur, with a choice of 10's of models ranging from £10 to £500 will fit any bike made in the last 25 years. Ok, this one, less so - but you watch just how quickly the UDH becomes the norm for all bikes going forward.
That Nucleon is also available without the Supre drive.....
I'm hoping for a UDH drpout for the G1
Most of the rear end is completely different on the UDH version though. It's basically a different bike from the BB backwards.
I'd love for gearboxes etc to become mainstream (I own one!) but it's just not going to happen anytime soon.
As someone who has to tweak the mech hangers on various bikes seemingly more frequently since going 12sp, this seems like a great idea to me.
No, I can't afford it, but I'm a total corporate pawn because I get the concept of trickle down from halo stuff, so I look forward to hopefully cheaper prices in future when it may be more attainable. I'm not sold on electric drivetrains but I've only ever tried early di2, so I'm open minded.
One of the reasons I've stuck with Shimano is the option of shifting under power, which this looks to take an interesting approach to.
Progress: I'm down with you.
Aside: I genuinely wonder of some of the posters who regularly string out threads like this realise how much they put others off posting on them as, well, they don't see the point, and can't be arsed with the hassle?
They now have tapered headsets, boost and metric shocks so my wheels and shock don’t fit.
A straight steerer fork can be run in a tapered frame. It’s possible to replace tapered steerer tubes with straight ones. I’d go so far as to say it’s possible to run pretty much any fork in any frame.
Non boost wheels can be run in boost frames, non boost hubs are definitely available across all budgets. If new is out of budget, there’s loads on the s/h market.
Pretty sure a lot of metric shocks can be converted with a spacer.
Non issue really
Steve look away, this one might give you a heart attack on the needless integration and resultant wasteful obsolescence
TBH the fact that UDH had to be implemented in order to make SRAM's direct mount mechs viable does at least mean there is now a standardized option for mech hangers with UDH.
As for their direct mount mech? I'm not a fan of creating an extra rigid interface where we have historically had a 'mechanical fuse' given the choice (which of course you do have) I'd still choose a conventional mount mech and a replaceable UDH hanger on any new frame.
The potential to do more damage to a frame by imparting impact loads directly into the dropout is what puts me off direct mount.
Now the UDH standard exists the real problem of finding the specific hanger to suit whichever old frame you happen to have is finally addressed, that's the real silver lining for us peasants who can't afford the posh kit...
Re gearboxes/hub gears, I wish they were good. Maybe they will be some day. But that fact that e-bikes have come along and added motors, but still mostly use rear mechs tells you how well they do the job. There's no conspiracy, mechs are a basic tech that works really well and have been polished and evolved for decades, gearboxes just don't compete. Every bike company would love to launch a brilliant gearbox bike, some of them have been trying forever, and failed without needing the mech mafia.

Free MemberSure, I appreciate technological progress, but our global ecological situation really needs us to prioritise maximising the useful life of products and ensuring things don’t go obsolete. It doesn’t do that
In this case, it's a step forward. UDH itself means less pointless duplication- we have to make an incredible shit-ton of mech hangers in order to have stock of all 1000 different variants even at a distributor level, never mind retail, it breeds waste. My scrap metal box has at least 5 hangers for bikes I don't have any more in it and there's as many spares in teh tool box because every bike I have uses a different one. (though, in fairness, that's old man reasoning- modern hangers are so tough, I probably don't need spares like that any more- a nice sign of progress.
When was the last time y'all broke a mech hanger, folks? Mine was on my Hemlock so that's 8 years! I probably broke 1 or 2 a year before that. Good progress. Some bikes end up in the bin because the manufacturer used some insane hanger that you can't find any more. And backwards compatible, properly 100% perfectly backwards compatible with mechs pretty much as far back as I've been alive. I want to fit an exage to a udh
(PS- yes I am aware that in some ways, this is just yet another item to stock.But we can see already that UDH is gaining a foothold, it'll have a net reduction of stock and excess over time.)
And we have mechs with replacable parts. Hallelujah. The most obvious thing in the world, something we've gone backwards on for years. Sure, mechs are also tougher than they were despite being more sticky-outey, but you generally can't get the bits and then they say "they're not designed for user repair" like that's a defence rather than an admission. It sucks.

Full MemberThe potential to do more damage to a frame by imparting impact loads directly into the dropout is what puts me off direct mount.
I'm not sure it exists. Sure, in an individual crash, you might have a situation where it causes damage, but overall- average it over 10000 crashes- and I'd be pretty amazed if the maths doesn't work out in the direct mount's favour. The strength in that part of the frame is massive now, with the rear axles being structural and the whole thing being basically triangulated, the force needed to distort the frame is huge. That's not new, basically as soon as we started getting really integrated hangers and axles and frames it was the case, it took a little while to really get the benefits of bolted in axles but they arrived a good long time ago. Trek's ABP hangers are not so different to UDH, frinstance.
UDH still has the "fuse" but at this point it's a 13A fuse where it used to be a 3A, the hanger part is stronger than they once were. Again not new, like I say, when was the last time you broke a hanger?
And the counterweight is that breaking/bending a hanger could make damage worse rather than prevent it. Twisting hangers can damage frames themselves, I remember doing some scary grinding on a frame to save it after having that happen and my Inspired can't take its original hanger at all any more, I had to grind the frame and also edit down another hanger and then bend it to counter the frame twist... but mechs in the wheel was always the worst case scenario and could damage everything since they got wrapped up, jammed,and generally took teh whole force of the wheel and applied it to places it was never supposed to. The fuse itself could burn your house down.
So over enough time, I bet 10p that it's a net benefit. It'll not feel that way, if you're the poor sod that has it happen. But you'll never even know, when you're the lucky sod that didn't have it damaged by the other ways. That's the danger for SRAM, the perception of "damage we invisibly prevented" is so low but the perception of one person or one tester with a busted frame is massive.
