Universal standards we are grateful for in cycling.
Rim diameter* – because that led to standard sized forks and frames that all put the axles in the same place, leading to wheels being interchangeable on frames, and same for tyres on wheels.
* slightly less so now 700c and 650b have joyfully arrived in MTB land.Posted 4 years ago
Only 3 different hub-cassette formats worth worrying about, plus a general requirement to match rear mech and its shifter, and the right chain for the number of sprockets on the back.Posted 4 years ago
edit: and matching rear mech with cassette size (more of an issue with road bikes), and total teeth capacity (more of an issue with MTBs).maximusmountainMember
We all know that headsets, bottom bracket standards, hub spacing, propriety parts and the like are the bane of our (well at least my) lives.
So lets list some things we are grateful are all the same on all bikes.
Pedal thread sizes.
left hand and right hand threads in the pedals.
mech bolt thread sizes (onto the hanger).
What other things have become a standard that we are thankful for?Posted 4 years ago

So not true.
Realise it’s not true in all cases, but I can buy a SRAM 9sp cassette, a KMC chain, and a Shimano derailleur and they’ll all play together just fine.
I think I’ve done better tan the madman above talking about interchangeable wheels in a world of 26″/27/5″/29″/700c/120mm/130mm/135mm/142mm/150mm/157mm/QR/9mm/10mm/12mm/X12Posted 4 years ago

I always feel a bit disappointed that pneumatic tyres are universal.
I’d love to see solid tyre nichemongers talking about how they make the trails come alive.
Always wondered if you could do some sort of reverse d30 thing for tyres – something that’s generally firm, but goes soft when there’s an impact.Posted 4 years agoDeveron53Member
There are very few ‘standards’ in cycling.
These are the only ones I can think of:
Bottle cage bolts
The distance between the holes in the frame that said bottle cage bolts go into
(although there is a bit of ‘play’ in most cages!)
The diameter of the water bottle itself
The diameter of the handlebar’s grip and lever attachment area
Chain pitch for derailleur systems
I reckon these ‘standards’ are the most widespread and longest lasting. No-one has successfully tinkered with them in almost 100 years.Posted 4 years ago
I think bottle cage mounts might be the winner?
What about modern sized shock springs (i.e. excluding old narrower ones)?
I thought I’d seen some “woman specific” small diameter bars.
And road bikes are different anyway.
Maybe wrong, but I think bar end plugs are universal* though?
chainring bolt diameter?
Spiderless cranks? And cheep ones are riveted.
Chain pitch for derailleur systems
There’s a very dead 1″ (or is it 2″, for 2 links?) standard. And belt drive?

Crud catchers? Front ones anyway, the clamps on the rear ones aren’t wide enough for me ISPs
Brake and gear cables are pretty much universal too
Leaving aside hydraulic and electric systems, road and MTB brake cables are different.Posted 4 years ago
Oooh!!! I’ve got it! Inner tube patches!

Racking my brain to think of somethign that’s actually universal – headset bolt?
Nope, my rigid has a special top-cap with an integral nut, which threads onto a screws onto a bolt thats about 15mm across inside the steerer. One of these: http://www.amazon.co.uk/FSA-Compressor-Carbon-steerer-spare/dp/B0038ZTHDAPosted 4 years agobrakesMember
I think we need a standard definition of universal standards.Posted 4 years ago
For me it’s a single standard for all components (e.g. bottle cage bolts), as compared to where you have competing standards (e.g. 44mm and 1 1/8″ head tubes). It’s not about single products or proprietary parts that aren’t standard (e.g. riveted chainrings).
