Anybody have a recommendation for tires for this? I'm running 48mm Compass tires on my rando bike, so considering RTPs here, but not sure yet. I will not be running fenders, and I measure 2.75'' in the rear for clearance.

Clearly, this calls for Nitto Moustache bars!

Can anyone tell me what the correct seat post diameter is for the 1986 model? I've struck out on 3 so far. 268 mm?

Classtime 

my 85 is 26.6

I just measured mine, a 1986 model, the other day at 26.6mm. I'm using the original Suntour Superbe seatpost, and it's also stamped 26.6mm. I plan to replace it, however, because it's too short for my needs. PM me if you're interested in buying, and I'll send photos.

Can any comment on geometry changes through the model years? Early more relaxed, upright?

Classtime 

Well, I need to share my mods. I think that straight bars are not for me on a bike that may not be ridden hard for most of its miles with most of the weight on the pedals. My Cimarron is my trailer-puller, grocery-getter, coffee-shopper. And every trip would make my wrists ache. So I worked out a trial with some Soma Oxford bars and I think it is an improvement. Because the XT 7 speed shifters were already on the bars with the stem, I put on a 7 speed FW and a late model Deore rear derailleur. During a 17 mile cruise:


One day it will have nice tires.

Your Soma Oxford bars look very similar to the Nitto Albatross I have on mine, and, though it took some getting used to, I now love it! I'm glad for the slightly more forward round part in the front as an option for more power. I was surprised by how much power I lost with a nearly upright position....

Very much like the Nitto bars with all the hand positions. I had these on a road bike with bar end shifters and much smaller Tektro brake levers. Then the bars were completely wrapped with Newbaums and my hands could grab anywhere. As cool as the original bars look and also work if I'm seriously pedaling, too often, this bike will rarely be seriously pedaled. But when the local single track opens up again, I will have to try this new set up on it.

I have RTB tires on mine. Second set actually as this bike was posted in this thread a while back. Great tire for this bike.

I wonder why Schwinn used decal colors that were nearly invisible against the background color of the bike. I have a red Cimarron with gold decals that one can barely see.

More details on the build process here, but I finally have my Cimarron up and running, thanks in no small part to some help from a fellow Bike Forum member.

Anyone know standover height or sizing on these? I'm 5'11" 32.5" book-measured inseam and thinking 20"?

countalmaviva 

I'm 5'10", my Cimarron measures 21" from center of crank to top of top tube, and it's a fine fit for me. My inseam, measuring with the book-in-the-crotch method, is 33.5". The standover on my bike with 2.2" tires is 31.5". Top tube is 23", center of seat tube to center of head tube.

It had been a while since I had ridden a mountain bike, vintage or otherwise. I'm used to road geometry, so there was some adjusting necessary, both mechanically and in terms of my expectations. The Cimarron is longer than I ride on a road frame, but that's OK since I'm not riding drop bars. Another factor, which I haven't solved yet, is that, because the bottom bracket is higher than on a road bike, getting my saddle high enough means that I have more difficulty getting my feet on the ground. I'm not doing any true off-road riding with my bike, so I prefer a saddle height more akin to what I'd ride on the road -- for efficiency purposes. Right now, I'm still using the lovely Suntour Superbe seatpost that was spec'd on this bike, but it's so short that I have it at maximum height, and it's still below my preferred position.

I would imagine the 21" Cimarron would be just right for you.

thumpism 

I'd say a 21" Cimarron. I have a 23" and its standover is comparable to a 25" road bike.

This is my third Cimarron, but my first time posting about these beauties. I have an 86, in green. and I had another in blue that was too large for me. I just bought his for two bills. I am stoked, because the black is legit. Not super happy about the underneath brake in the rear, but for the look I will take it. I am going to make this a drop bar conversion. sun tour bar ends, and long black stem. Anyway... isn't she pretty? Everything is original down to the tires. Bought it from a nice wealthy couple in rancho sante fe. was a wall hanger. rims have no signs of use, but there are plenty of scratches and blemishes. I love it. The seat tube busted. The top came apart from the tube. Just happened, so I am searching for a period correct 26.6 seat post. the original on this one is about 16 inches... not kidding.

Classtime 

Nice. A black Deore XT post comes in 26.6. I think boulder bicycles has some.

Thank you, I went through my parts bin and found one. A little crusty, but after some sanding and some mothers it will look good.

countalmaviva 

Niiiice! Curious about the make/brand on your busted seat post. My 86 has a 26.6mm Suntour Superbe that is too short.

Also, if those thumbies are 8s, I may have interest to buy or trade...

I'll just throw this out there: I'd be VERY interested in a good condition Cimarron in GREEN, smaller frame. Working this weekend on the red one i got from wrk101, with a taller stem and 165mm crank, and will see how that works out for my wife, or myself as we're close enough to the same size. If it's as nice as I expect then a matching one would be pretty cool!

Hey Al,
I just got a small frame red Cimarron. I think it’s 17.5” center to center seatpost. I’m not sure how Schwinn sized these. I live in Edgewater, Chicago, near lake and Loyola’s campus. Let me know if you’re interested. The frame looks worn but not worn out. It’s too small for my needs but would hold for kids if you’re not interested. Thanks,
leif

Hey JT! I might be. I'll message you.

1988 Schwinn Cimarron with drop bars and Suntour Command shifters.

Anyone have any real world weights on Schwinn Cimarron frames? 6lbs? 7lbs?
