14-XX 8spd casette doesn’t exist…
I’ll need a shimano 9spd 14-25 casette then scrap the biggest gear and swap the spacer between each cog for the one on my older 8spd casette. YEA!!!
I vote for Ben’s suggestion. 50 x 14? You’re fucking shitting me.
50 x 12 would have made some sense, that’s a typical compact crank and cassette combination. But no, lets not bother looking at company product lines when making stupid rules.
There is no 2013 Campy 11 speed Cassette with 14t minimum. There is only a Chorus 10spd option.
There is only a Tiagra 2013 14t minimum from Shim. There is evidently no 14t minimum shimano 11spd option either.
If you’re a senior 3 with campy 11 speed… And shimano at the very least used to make it in ultegra, if you shop soon enough, stores might still have them in stock. Wiggles still has some. La Cordée did not so long ago at least.
As Eric mentionned above, you can also just use your limit screw. If you take the two lower gears out from a 12-xx, you end up with a 14-xx with two gears less.
Do you seriously think the sort of people who inspect bikes at races are going to watch you shift up/down to prove you’ve over-set your limit screw and can’t go past 14 t? Most of them probably don’t even know what a limit-screw is or does.
They are really going to measure the distance travelled on a roll test to nearest cm too I bet (as specified by the regs) accounting for the deadzone in the pawls of a rear hub (which can lead to appreciable error if your precision is specified to the nearest 5 mm).
Why would an Sr3 not have Campy 11spd? Athena is fairly cheap, most of the high end bike gear is bought by non-racers anyway. Lots of people with $$$ bikes in the young/rich 27-30 year old crowd.
When someone writes a rule requiring equipment that is highly non-standard, using a measurement precision impractical in the setting it’s meant for, it’s generally fairly obvious to me it was written by someone who didn’t actually think very much.
Actually, the limit screw technique will work and is used commonly for jr and cadet racers. They’ll simply have you down shift all the way, and roll the bike. If it stays on the 14, you’re fine.
I doubt that. They simply have 2 chalk lines, “align” the cranks and move the bike until the cranks are “aligned” again. I have no idea how much leeway they give it, I’ve just seen them do it, without paying too much attention.
Maybe this is a dumb question, but what is the intention of gearing restrictions? Is it to reduce the speed of the peloton on flats? Do senior 3 pelotons EVER go 54kph even before the gearing restrictions?
From startbikeracing.com, These restrictions reduce the likelihood that races be dominated by the early bloomers , who are physiologically years older than other kids. They won’t be able to pull off monster breakaways in a huge gear that less well-developed kids can’t push. Last, it helps keep junior packs together, allowing the riders to learn and refine their pack riding skills and strategies.
So I guess restrictions kind of make sense for younger riders (under 18?), but for someone just under 30 who has been riding for over a decade, I don’t get it.
