Oh God, I just found a thread with people fitting clutch derailleurs to 1x TT bikes. I feel dumber just reading it.

Someone said about this they really like the paint scheme... WTF?!?!?! That's not a paint scheme, it's *&£$%^£ black.

I've been dehydrated, gotten serious bonks, nausea, exhausted, seen people vomit, even crash from exhaustion. I have had my legs run into full lactate overload and burn, and ridden to total glycogen depletion to where I lost my ability to really accelerate and had to slow. But cramp to the point of stopping and getting off the bike, like the way a track sprinter has to stop when cramping? Not once. And yet, the announcers talked like it was almost normal.
Well, you're older than me, so I'll have to defer to your 40+ years of riding and sage wisdom on this one.Merckx index said:It’s happened to me several times, a couple of times on very long rides, where I had to stop for a while.Alpe d'Huez said:In my 30+ years of cycling...
I think you're discounting the impact of the swim leg. I have seen swimmers cramp up a couple of times, to the point where lifeguards go get them. I've heard from runners about bailing from races because of cramping as well. I'm no expert, but it looks to me like cramping up to the point of stopping in triathlons is much more common than in cycling (where cramping does happen as well, though seemingly usually in the debilitating but not paralyzing sort).Alpe d'Huez said:In my 30+ years of cycling.

Boeing said:New thred topic idea? Should triathletes be allowed to post here?
I haven't read the thread but there are things that running single chainring enables which can result in quite a few watts saving for those interesting in TT riding. The gains are more to do with being able to narrow Q-factor than the actual removal of a ring from an existing set up, the latter having a very limited benefit - I guess it might cough up a watt or two. Ruin aero? No. Potential tiny gain, yes. Narrowing Q factor though can be somewhat more worthwhile for aero gains.King Boonen said:Is your second chainring ruining your aerodynamics..?

"Also, it should be noted a rider would likely influence these numbers as the movement of legs, crank, shoes, pedals, etc. would all alter the airflow through the drivetrain area. Still, the results are worthy of further discussion and testing. "
Probably find it to be even more aero without the rider then...![]()

Really? Why? My Monstercross has no chainguide and a 4 year old, normal, non-single ring specific chainring and a non-clutch, Deore mech on it and I hardly ever drop my chain when riding MTB trails. What are people doing on a TT that's causing them to drop their chain?
Ask David Millar. He ran a naked single ring in 2003 TdF prologue and dropped the chain with 500m to go. Lost by 0.1 sec to Brad McGee:King Boonen said:Alex Simmons/RST said:I'd still run a chain guide for the front though if not riding a fixed gear.

So one data point 13 years ago? Doesn't seem very relevant.

For a race that significant, I think it is. And if, as people here are so keen to point out, having such a device present no performance disadvantage but may indeed save a race, then why not?
