Eroica CA gravel ride - 650b or 700c?

Hey gang,

I'm riding the Nova Eroica California short route in a few weeks... https://eroica.cc/en/nova-california...ca-short-route

It's mix of pavement and gravel for 72 miles (56 miles are gravel). All things being equal, would you ride your 650b x 2.1" wheels/tires or your 700c x 40 wheels/tires? I'm thinking I'll take the 700c wheelset since there doesn't seem to be anything too gnarly. But those 2.1 inch tires would sure feel nice and plush for 72 miles... What does the collective wisdom of BF think? Thanks in advance...

650b really wasnt a common/popular thing back in the day. Nor were 700x40 tires. I would be surprised to see either be Eroica gear. Have you read the rules/suggestions/guidelines of Eroica?

Are you sure it’s 56 miles of gravel?

Appears to be correct... I did the vintage bike version of the same ride a few years ago and it was mostly gravel (some private roads too)...

This is NOVA EROICA, not Eroica... I've ridden Eroica events for years so, yes, I have read the rules. This is for modern bikes, not vintage. I don't have the reading issue.

Woah, coming off the top ropes there.

Ok then.

Well, you questioned whether I had read the rules... Just making it clear that I have. Wrestling analogies are fun, though.

Cool. The page you linked to was confusing, first saying 56 miles of pavement in the text and showing a mostly paved route on the Komoot route profile (including “lastricato,” which I thought was equivalent to cobblestone, but I didn’t know that kind of road existed in California!) and the switching it around to 56 miles gravel in the route summary section. I looked at RWGPS, too, and thought it was 56 miles paved roads, but maybe I looked at the wrong year, wrong ride, or just simply misread.

Anyway, I was thinking that in a situation where you might get up in a fast gruppetto, 700c might feel more natural, but I guess since the route isn’t gnarly whatever the surface mix, choosing to go the comfort route with wider 650b isn’t a bad way to call it.

Yeah, 56 miles of gravel caught my eye... According to the website:

"The Santa Lucia route combines 56 miles of pavement and approximately 16 miles of gravel for a total of 72-miles in the saddle."

Really depends on the type of gravel. I'm gonna venture a guess here that it'll be more like unpaved roads and less like proper trails, in which case the 700x40 would be my weapon of choice, with the expectation that there will be a good chance I'd be underbiked.

650b x2.1 is fun, a lot of fun….on single track and muddy gravel in February. It is a hell of a lot of work, and heavy, and slow if you’re course doesn't have much of those things in it, however. 700x40 is a a nice split between x38 and x42…if you’re going to for time, ride the 700s. IMO, the only way 700x40 is underbiked is if the route is laden with big chunky rocks (that wish they were boulders) and rooty single track. Enjoy!

Thanks... yeah, I'm leaning toward using the 700x40 too. I've done parts of the course before and it's mostly tame gravel with some areas of sand. There is no single-track or anything super chunky. The 650b x 2.1 would be super comfortable but is probably overkill. Also, I did the vintage ride on the same gravel before, using a 1984 Bianchi with 700x28 tires. Now, that was hairy but fun...

NOVA Eroica is mostly paved.

I'm a local and ride the roads around the Eroica course quite a bit. I can confirm that the full course (factoring in the coastal run from Cambria to Cayucos, is mostly paved. The only "gravel" are the dirt roads (no single track or chunky gravel) of Santa Rita and Cypress Mountain. Otherwise, it's all paved. The run in to Cypress can be very potholed, but that portion is paved as well.

Thanks... So I guess I'll go with the 700c wheel set... The 650b x 2.1" seems to be overkill then.

Yes, I think so. I 'm riding with 700C 38mm Vittoria Terreno Dry tires. They have a good non-knobbed center section for the paved sections.

Update

The 700x40 wheelset was the right choice for this ride... Nothing too chunky... These Zipp G40 tires are amazing too...
