In the back of my mind I’m wondering if a tiny chainring and subsequently spending more time in smaller cogs might result in efficiency losses greater than the sum of the weight savings.

I would assume yes seeing the difference between losing 10lbs vs gaining 10w

And weight loss only helps you on climbs and accelerating whereas power helps you everywhere

Just curious when people point out the quietness of different trainers, what fans are you all using? My fans are the loudest thing in the room, way louder than any trainer I've used, so I don't really get who cares how loud the trainer is when I can't hear anything over the fans anyway.

I’m using blower fans they’re nice and quiet

I put together the SB20 - this thing is rad, however I'm trying to figure out ERG mode. I have never used a trainer so I don't know what I'm doing outside of the sim mode.

For ERG, are you supposed to maintain cadence and the trainer will adjust resistance to the target wattage, or is it more complex than that? I had a hell of time landing on some wattages without oscillating over/under.

ERG is probably the weakest aspect of the SB20. It's not responsive enough and it has a very high wattage floor. I expect it to get better with firmware updates...maybe.

Saris H3.

The trainer itself is ultra quiet except for the freewheel (can be quietened with more grease apparently). Drivetrain of the attached bike is louder than the trainer in actual use, so not much noise at all.

And yes, the fans are far louder.

It's the original Tacx Neo from 2015, but it's not like turbo technology has moved on hugely. One caveat emptor thing here is that Garmin does not like people repairing its products, so if it's duff and given you don't have warranty you've just bought a big paperweight.

Can anyone provide comments on using a Peloton versus the alternative options for training?

I currently have a Wahoo Kickr. I’ve used both Zwift and Traineroad with decent outcomes. It’s served me well but the Mrs is now expressing interest in indoor training. I’m considering a Peloton.

My priorities are more towards training for gravel events, being able to drop friends on group rides etc. Nothing crazy serious. She’s more interested in general fitness.

Can anyone provide a view here? Can you get similar outcomes on a peloton versus the highly structured programs on Trainerroad?

Two issues with Peloton.

1) Where do they go from here?
2) If you buy the hardware, it’s a spin bike that doesn’t coast. The resistance is still crudely controlled even with the new Peloton+ bike.

Your SO probably won’t like any other option as much though. You could get the sub and see how she gets by using it in conjunction with the KICKR.

One of us. One of us.

I don’t think Peloton is going anywhere but the SB20 is a better choice. My buddy has a Peloton, I have a SB20. It’s a much better bike to simulate road riding.

It’s also cheaper to use Pelotons app with a third party bike. You can’t (easily) use a Peloton bike with Zwift/etc.

Not sure what crank you’re running but I’m planning to run a Wolftooth direct mount chainring for my Force 22 GXP cranks which goes down to a 26t as the smallest. Coupling this with an 11-28 cassette should give me the range I want and a not great but not terrible 3t jump between teeth. This also means I can avoid having to mount a longer cage RD or a road link which is a few extra grams of weight savings.

I’m thinking to have easier than a 1:1 ratio for 700x25 tires in case of terrible wind. According to this site that would put me at a 80rpm cadence if I’m aiming for a 1 hour finish. Probably over ambitious but this is expensive as hell and I don’t want to come back thinking I had some gas left in the tank.

Feel free to msg me if you want to chat, this will be my first time so I’m undoubtedly going to get a ton of poo poo wrong

I did! A buddy of mine got in as well. Think I’m going to make a short trip out of it with my wife and my buddy will join us near the day of the hill climb.

Do you have a ride down from the top? I might be able to squeeze another person in depending on if we drive there or fly and rent a car. I haven’t done much planning yet.

I'm making a gear display for the SB20, but I just learned this thing only accepts 2 BLE connections at once. Do you folks use the Stages link app for any functionality other than gear display?

ANT+ has no limit on connections, but I don't want to learn how to use ANT. Why won't stages just implement the ANT+ gear shift profile so we can use our god drat head units.

I discovered today that you can scrub through trainerroad workouts.

Sadly only after dropping my phone and somehow skipping 1/3 of the workout I was on - but got back to it eventually.

This will make the needlessly long 10 minute recovery intervals go (literally) much faster, though I really just need to increase the intensity I guess.

I had to put 120lbs of sandbags on the legs of my trainer to keep it from walking forward 1-2ft in every sprint.

Not mine, but this guy does similar:

I don't sprint that hard and tilt my bike everywhere. I don't think I've really pushed more than 500 watts for any significant length of time. If you insist on swinging your bike around like that, shouldn't you get one of those tilting platforms?

I can only hit 1000 watts for a few seconds but it was enough to make my bike move across my kitchen floor. Now my bike is in my conservatory and have the front wheel wedged up against a cupboard, problem solved. Though the movement seemed to be more up and down of the front wheel rather than from side to side.

It’s not swinging, it’s hopping. I don’t swing my bike at all because that would be horrific on a trainer without a rocker plate…it’s bad even with one.

It's from both a slight upstroke during sprints and also from natural rebound from trying to kick my legs forward and down?

Body weight is also a factor. I’m 62kg. There’s literally less weight keeping the trainer in place even though I’m still doing 15s@900W or whatever. Or 60s@615W. That’s why I had 2x60lb sandbags on my trainer legs before I got my SB20, which does. not. move.

A power curve is an x-y plot of best power and duration.

It can be for either a specific ride, or for the last year, or all time.

So, at any point x of duration, say, 5 minutes, the corresponding y power is your best average power for 5 minutes for that ride, or for every ride, depending on what the power curve is representing.

When people talk about it, they generally mean either for the last 90 days (if they care about numbers that have any bearing on their current fitness), or all time (if they got fat in the pandemic and don't want to think about how far away from a PR they are).

Many websites will generate a power curve for you. I think Strava does it if you're premium, trainer road does, Xert does, intervals.icu does for freemium, etc.
