Issue Mid-Ride

Post by ohwhen » February 2nd, 2025, 7:48 pm

I'm writing hoping to get some advice on an issue I've experienced mid-ride on my BikeErg.

For context: I (almost always) ride on a constant damper setting (around 5) for an hour or so at a time, twice daily. The issue is, that at approximately 30-40 minutes into the ride, I experience the feeling of increased resistance despite not changing any settings or altering the ride.

In real-world cycling terms, it's as though I turn a corner and am met with a headwind, or an incline, paired with a grittier road surface to contend with (the bike losing a lot of 'smoothness').

This becomes a struggle and normally does not go away until 50 minutes or an hour into the ride when it tends to normalise.

I've already contacted Concept2 and their solution was to send me a replacement, which has not fixed the issue.

I''m hoping to find folks with similar issues or some help as my patience is starting to wear thin.

has not fixed the issue.
Which suggests it's not a machine problem, unless it's the air flow that's changed somehow. Have you tried readjusting drag? It's possible that this can change with time and maybe temperature.

hey thanks for responding and for your suggestion

it's reassuring to know you think it's likely not a machine fault, but the issue persists

it could be noteworthy to mention that i use a vacmaster cardio54 at approximately 2 o'clock, quite close to the erg/myself as to not obstruct the airflow from the fan.

as per your suggestion, i've adjusted the drag settings, but to no avail. full recalibration does not help, either.

i'm at a loss for ideas; it is a real struggle when the issue 'kicks in' and still happens every single ride.

I experience the feeling of increased resistance
The Rowerg, using Ergdata, shows us both peak and average forces, in Newtons. Can you see these forces and any changes on the Bikeerg too?

Can you be sure the energy paths in use are the same for the entire WO? If not it's possible the the sensations they create may vary.

Do you monitor HR/Watts/O2 etc for the entire WO, in order to identify drift?
