Here is the bike in question ^^^
The drivetrain is completely stock at the moment.
Do you think there is any way I could have a LBS put a triple chain ring with a low gear of 30-ish on? I would really like some super easy climbing gears for a couple 'fondo' rides this year and even
50/34, 11-32 is a bit much for me right now. I would like to be able to spin 90+ even at very low speeds.
Any help appreciated,
Thanks!
A 30 tooth triple is only 12% lower than a 34 chainring. That's less than two cog shifts.
One of the local riders has a mountain bike rear derailleur and what I think is a 34 or 36 big cog. It's probably 10-speed, not 11. It works great for her.
That really wide range cassette would be really annoying to me on less extreme grades. I don't like big jumps between shifts, because I like to keep my cadence between 90 and 100. I have an 11-28 11-speed and even that jumps from 97-99 down to 86-87 on certain shifts--too much.
But on a big ride with extreme grades, I'd swap it in.

I'm thinking about a second bike with Campagnolo 30-39-52 and either 12-25 or 12-29 11-speed. It's 30-29 is a couple of shifts lower than a 34-28. The main advantage is very close gears in the middle chainring in the whole range of 10-22 mph. And a good set of climbing gears in the small chainring for anything except the most extreme grades.
And 11-speed Campagnolo can use Shimano 11 speed wheels with the Shimano or Sram cassettes, since the cog spacing is very similar.
