Interesting thread. I own a 57 Sam set up with drop bars / 42mm gravel kings. I had the opportunity to build a lugged 54 roadini, I’m luckily on the cusp of both sizes. What persuaded me to follow through despite the quite obvious similarities, was the ability to size down. Looking forward to a more road build. Will report back once I have some riding done, super stoked.

I have more or less the same questions as Mike in BK. I ride a 2017 58cm Sam, and the equivalent sized Roadini (a 57cm as it happens) has almost identical numbers. The number I'm most interested in would be the front center. But they don't list those stats anymore in the geo charts? From email exchange with Will, the two frames will ride very similarly. I wouldn't be surprised if the tubing is indeed slightly different - or not - but I'm not sure if I'd notice it. What I would notice, however, is the front center measurement; Ideally I would want more than I currently get with my Sam (61.8cm, according to Bike Insights).

Hi Brenton,

If you have a 57 Roadini and a 57 Sam from a recent MIT generation, their geos looks very similar (like, very). With the Sam being more stout and a little longer, how would you compare the rides? Interested in the feel on the road and capabilities on non-paved roads (which you've already described a bit here).

Thanks!
Mike

I ride my Roadini all over. I'm on a 57 as well. 6'1" and 185lbs. I have 32H dyad hoops. Only used Ultradynamico Cava 42s on it so far.

I have thrown the rear wheel out of true after getting "air" off some roots on familiar trails. That's about as crazy as I get, and I've learned not to beat on it the way I can do with my Sam. Sam has 36 hole Atlas wheels.

Looking forward to answers to this. I have a Hilsen set up for road riding, with slicks and a dark-boston-winter-inspired dynamo, and I love it -- it's fast and so comfortable -- and have no plans to make any big changes.
(Except maybe to Paul brakes -- big for the wallet.) 
Thinking of getting a Roadini or an Atlantis next, for trail riding but also, sometimes, commuting. On first glance, it seems like the Atlantis would be the smart choice, but I like the geo of the roadini better, like that it's a little lighter, like that the lugged version seems more rack friendly, and I'm just not convinced that a somewhat experienced (def not expert) rider needs anything bigger than a 43/45 tired unless he/she is hitting mountain trails. (For which a mountain bike will always be better.) I have a crust bombora, which I would gift to my son, and on all kinds of trails I've never felt any ride-feel difference between a 42 tire and a 50. So curious about others' experiences.
Jay, thanks for asking this questions, and as far as tire advice, I really love the soma cazaderos for what you're describing.
Cheers!

I have the 2023 Roadini, size 57.  I LOVE the bike and how it feels, every time I get on it after a long break (riding another bike on snowy/salty roads) I'm reminded of just how good it fits, handles, and feels.

I'm thinking of adding a third wheel set, for mainly unpaved riding (more below).  I'm curious as to your experience with this bike on gravel roads, trails, etc.  I realize bike configs will differ, as to the specific riding conditions, but to me this is not a road bike like the ones I've had previously, so I want to push the envelope and see what terrain I can ride, somewhat comfortably.

Recap: Bought it a year ago and had two wheel sets from the start, one with Dura-Ace wheels I already had, and 30mm tires for road rides with a friend, who is faster than me (me and the bike can keep up! so it has replaced my road bike); the other with new 105 hubs and H plus son archetype rims with 43mm GKSS tires for every other ride, which includes rail trails, short sections of gravel paths connecting roads, and 100% paved rides when on my own (I like the added comfort and versatility over the 30mm tires).  Swapping wheels is so easy, pop the quick release on the TRP levers and on the other one on the brake callipers, swap wheels, barrel adjuster on the calliper to adjust pads to rim, done.  I'm always playing records when messing around with the bike, and this is a "one song" adjustment lol

If I was to add a third wheel set, I think I would want go tubeless, with supple 43-45mm tires with an aggressive tread.  I want to maximize comfort and also have a tire that can corner on loose gravel, and ride comfortably over choppy gravel roads (on longer mixed surface rides).  The 43mm GKSS tires are great, and I run that at 30psi if mixed surface, but they lack comfort on chunky terrain and don't handle my twisty gravel trails very well (where as my Salsa Fargo with 2.2" tubeless tires, smooth centre / knobby corners, is great).

Looking for your input about this bike's capability unpaved/off-road, our experience, and recommendations for TLR rims, and tires as described above.  Thanks!
