    No idea clearly if the case is has merit though IrCOd assume they have had legal advice.

    DoesnrCOt seem logically to have much merit the limit on gearing, and seems rather arbitrary see also bar width.

    This is a preposterous claim from SRAM. Since with the present regulations we have beoken a mile a minute record there seems little need for higher gearing and ANY fear can be spun out on decents. So since while the peleton is riding all day at the preposterous speeds of 33 mph that is well below the speed possible with present gearing. Rather than improve safety, higher gearing would simply put the peleton as a whole in more danger as they attempted to keep up with the few riders that can develop the power to sustain higher gearing.
    Would you like to see every race instead of a race, turned into nothing more than a time trial?

    Pros are using big chainrings for efficiency, and note the average speeds particularly flatter one day classics can be high, but even so folks using
    big chainrings arenrCOt likely to be using the last few cogs much.

    This much like some of their disk brake rotors are sharp etc stuff seems
    knee jerk and data less reaction.

    Ie I donrCOt recall any data being released or suggested to back up their reasoning.

    Would you like to see every race instead of a race, turned into nothing
    more than a time trial?

    In the early days of mountain bike races, the rule book had
    two entries.

    1. We all start on the same line together.
    2. First rider across the finish line wins.

    I think that covers all the important details. Anything more

    You and I agree 90% of the time and we agree that regulating bicycle races is pretty silly. But PERHAPS in the interests of safety weight linits are not such a bad idea. At the speeds that pros are now riding, I don't think that helmets are of much help. But they DO keep a riders head from direct contact with the ground. And riders tending to be young and overly masculine, setting rules to keep from being able to publish pretty disgusting pictures of crashes in races is probably a good idea.
    I do not like the lengths to which the UCI has gone but some regulation of the sport is probably justified.

    I think that SRAM has some sort of argument because they want to use 1 x's I think in order to climb in the big ring they are using 49's instead of 54's. So they want to put 9 tooth cogs on the cassettes. While I am dead slow, I am passed once in awhile by young men who believe they are fast.
    A 28 mm tire is 88" in circumferance. Or 7.4 feet. Or .0014 miles.
    A 54-11 is about 5 rev0olutions of the wheels per revolution of the crank.
    That is .007 miles pedr turn of the crank.
    Pros have a cadence of 75 or .525 per minute or 31 mph in high gear but break aways are doing this ALL DAY, day after day in grand tours.
    So while the break aways are in high gear, they are only gaining about 2 seconds per mile on the peleton.
    This tells me that until they have a certain lead, the peleton in only riding a slightly lower cadence.
    Now, in TT's they are riding a 56-11 or 10. Let's assume a 10 SRAM. This means a distance of 0.0126 per revolution of the pedals. Gall in the final TT did 60 mph or a cadence of 79 rpm.
    By looking at these numbers, you can see the the main peleton is in high gear ALL of the time in a race. I really don't think that they can gain anything by raising the top gear ratios. Efficiency isn't all that high at 75 rpm cadence and 60 mph is insane and ONLY achieveable because of the shortening of the TT to 13-18 minutes.
    Can you gain anything by raising the gears? The Aerodynamics of the bike can't be increased by more than 1 or 2% at this point. And you could only get that much by going back to rim brakes.
    Riders already are about as aero as they can go. Because the absolute speed are relatively low, changes in helmet shape would add so little that it would be indetectable. The same with wheel shape after 80 mm depth. I would say that there can be NO changes that would detectably increase the speeds of the peleton though the Tour de France next yoear could always being some surprises but that would most likely be in the form of drugs that increase the capacity of muscles to process food into energy.

    There's a lot more wrong in tommys post than just that.

    No one is riding at at 60 mph, or at a cadence of 75. Cadences the pro
    peloton is typically in the 90's when not flat out racing, and typically
    ~100 when in a breakaway, trying to close a gap, or setting up a hard
    tempo to discourage attacks.You will see cadences as low as 80 in ITTs,
    but not often, usually closer to 90 for a 40K effort, higher for shorter events. It's easy enough to check, just watch a video and count the
    pedal strokes.

    I'd suggest tommy made a simple typo when he wrote 60 mph and meant to
    write kph, but he did it more than once.

    And I'm not sure why he would use Felix Gall as an example - he isn't
    exactly known for his time trialing prowess. Let's look to Filippo Ganna
    for that. He's the current world hour record holder, twice world TT
    champion, and won the shortened (and dead flat) ITT in this years Vuelta
    with an average speed of 56.244 KPH. Video highlights are available on
    the web, he's pedaling at just over 100 for the duration, keeping over
    60 KPH for extended periods.

    For even more detail we can look to Gannas would hour effort.

    https://www.cyclingnews.com/news/euro75k-per-hour-filippo-gannas-full-gear-and-kit-list-for-his-hour-record-attempt/

    "Ganna was running....a 64-tooth chainring. This was be paired with a
    14-tooth rear cog"

    "Hitting his mark of 56.792km, Ganna would have had to average over 98RPM."

    As for the SRAM vs UCI issue, there's no data to support the UCIs
    position. From a practical perspective, a gear restriction wont do
    anything to enhance safety. If anything, it has the potential to make
    this less safe, since this will force the sprinters to work at higher
    cadences which are inherently less stable.

    The UCI seems to have been sucked in by some zealot within SafeR - the
    same morons who pushed the new narrow handlebar ban.
