In an email last week, Monet Berger received some upsetting news. “I nearly cried when I read it,” Ms. Berger said. “My heart sank.”

The local press reaction was dramatic, as well. “Total Tribeca Meltdown Alert,” the Tribeca Citizen warned. Racked.com prevailed upon its readership to maintain calm: “SoulCycle Tribeca Closes for Renovations — Nobody Panic!”

Yes, the spinnerati of downtown Manhattan has had to face its greatest fear: The TriBeCa flagship studio of SoulCycle, the chain of indoor cycling studios that is a haven to celebrities and everyday-workout-obsessives alike, closed last Monday for renovations, for three weeks. The construction, which began in February and was to have been finished by Labor Day, will double the location’s showers, bathrooms and locker space.

The company, whose clientele pays up to $70 (for priority booking) for a 45- or 60-minute class, anticipated the concern of its devotees. In announcing the closure, it tried to strike a reassuring tone, promising to schedule additional classes at nearby studios. “We understand that SOUL is an important part of your day,” said the email alert to SoulCycle disciples.
