92 Stumpjumper Comp, one smooth ride

AdventureManCO 

YESSSSSSSSSSSSSS I LOVE the '92 Stumpy in pink! It is on my 'favorites' list and I couldn't turn one down if I saw one (w/ matching fork). KILLER bike, my friend!

There was one at a co-op I frequented several years ago, but alas, it didn't have the matching fork, so I passed it by. You have done that bike justice. Just awesome.

I have yet to do the canti stud move to my Trek 990, but it is going to happen, thank you for the inspiration. Trash bike couldn't have had a better custodian, just fantastic work.

Thanks. Moving the studs was easy. Heat one up till the brazing gets soft, pull it off with a pair of channel locks, decide how far you want to move it up, and use a piece of metal bar like I did using the original stud to hold the repositioned one in place. I didn't even have to order new studs- just cleaned and used originals. Once brazed, switch sides and use the newly repositioned stud as the holder to align the second stud. I feel a little silly, since I abandoned it and went disc, but, if there's one lesson from it, I wish I had of repositioned those canti studs years ago.
Go for it!!!!

West va this weekend :

Lovely. And thank you!

finally got around to swapping forks. the Soma I was using had really long a to c ie 425mm and my Serotta was built for a rs mag21 that was like 405 a to c but when I went rigid I could not find a fork with anything close and finally came across a vintage fork with 405 a to c. feels much better and even tho it is chrome does not look as goofy.

What a great looking bike!

I like chrome forks.

I once had a Serotta Atlanta road bike.
They made high quality frames for sure.

Enjoy.

It's that time of the year with Halloween decorations popping up.

This is available locally for under $100. Thinking about making it a single speed winter commuter with swept back bars. Joining the club.

I'm not sure I'd really call this a "conversion" as this is pretty much what a 1988 Schwinn Woodlands looked like right out of the catalog, just with a slighly different color to the paint and some decals (this bike was starting to rust pretty badly, I stepped in just in the nick of time).



Handlebar is a new Wald replacement in similar style to the stock one, may be a little higher than factory. Brakes are obviously newer, the rest is pretty much straight as it was, just cleaned up nicely. Tires are an urban somewhat BMX inspired tread, great for city paths and a touch of gravel.

It's a very good rider and extremely simple as it's just a 10 speed.

Hi, everyone, I’m new to this forum. After I get 10 posts, I will share my collection / fleet! Does anyone have certain bars they prefer? I’ve seen a number of VO and Soma bars in here, but there are so many options that it’s difficult to know where to start.

merziac

Unless you get very lucky, you usually have to just bite the bullet and try a couple to see if they work for you and move on from there.

Keep in mind as you probably know with a fleet that bars are not just bars, many factors may or may not make them work but you have to start somewhere.

^ This.

About the best suggestion I can make is: attempt to get an estimate of where you feel hands should sit while riding, in the most-comfortable preferred riding position. Then measure the degree of sweep, the rise and width of bar that might result in that hand position. It'll at least allow you to focus on those bars with roughly similar characteristics, discarding the rest. At which point, it'll be trial-and-error. You might consider an adjustable angle stem, too, at least during the effort to find the right bar. It'll allow a given bar to work in a wider range of positions.


gladhandbart -- Here is a website that has links to a wide range of bar styles. It's a good place to check out the varieties. Lots of different amounts of rise, back sweep (angle), width.

Thanks for the advice and the link! Most of my bikes have quill stems, so I’m not sure how simple it is to swap bars on those… I need to do more research.

it is easy, not like a road bar where you have the tape to deal with.

Not a detailed pic, and not drive side either! But a good representation of what I fixed up our vintage MTBs for.

Bikes are a 1987 Schwinn Cimarron and a 1992 Bridgestone BB-1.
Bridgestone was a recent FB find. It got an overhaul, generic NR bars, upgrades to the seat post and to old DiaCompe brake levers, ergo grips, and the Brooks B67S from my wife’s Bob Jackson mixte. Also some alloy chainrings including a spiffy red 48t. Pedals are Deore M735 (?) a rough looking but smooth spinning bargain from eBay.
I think the BB-1 was 1992-only; I’ve seen it in the Bridgestone catalog, where Grant P stated that it was an upgrade from their previous CB (City Bike). Maybe the latter hadn't sold well; they had three versions which may have been too many for that market segment; Grant called the BB the 'Basic Bridgestone,' so nothing fancy but a solid base to build on. Wife wanted a step-through frame like her mixte, and this fit the bill perfectly, esp since it’s the larger of the step through frames offered at 19-1/2”.
I’ve had the Schwinn for a few years but didn’t do anything with it till just before this trip, and in my haste made some mistakes. It now has the crankset and wheels from a Specialized Stumpjumper Sport, since I didn’t like the original 175mm crank and Biopace rings, but the small chainring turns out not to be usable. I’ll be swapping something else in later; I barely got to this point before leaving on this trip. It’s sporting Suntour Superbe Pro pedals from the parts bin and a Brooks B17 Champion that I’m having trouble getting tensioned—it keeps squeaking.
Both bikes got Maxxis DTH tires; I got both sizes and thought my wife might like the 2.3s on her Bridgestone, but they wouldn’t fit. I like ‘em.

Location is Grand Island in Michigan’s Upper Peninsula, a beautiful area. We did the 20+ mile loop around the island, and that was a bit much for these old bikes (and their even older motors), lots of crushed gravel but also some pretty steep and rutted paths, mud, thick sand, etc. And a few (swarms of) biting flies, even this late in the year, just for motivation when you’re not moving fast enough. All in all though, a great day out.

Thanks for sharing the details of your upgrades and your ride. I’m wondering why you didn’t like the Biopace chainrings. I recently rebuilt a Crosscut that has those rings on it. I kept them because I was curious about them and they were original to the bike. So far I’m neutral on them. They seem to work fine but I can’t detect a difference as I ride. Was it just a baby with the bath water situation for you because you replaced the whole crankset?

Chicago Al 

You’ve got it, Biopace might be fine. I only rode the bike with the original cranks briefly, not enough for a fair test, but I formed the idea that something didn’t feel right, maybe the 175 crank length (I am 5’ 6” with short legs), maybe the Biopace. Or maybe I just wasn’t used to a MTB with 26” wheels and was being unfair.

I decided to do a quick overhaul on the Cimarron for this trip as the other two MTB projects (for me) I have were further from ready. I was maybe going to just go with the original crankset, but when I took the rings off to clean them I neglected to note how they are supposed to line up. So I thought I’d try the 165mm triple off my Univega Alpina project…no go, they’re for a different spindle and the small ring nearly hit the chainstay. Next choice was the 170 cranks off the Stumpjumper Sport, since they were freshly cleaned. Once I had that crankset on I figured the newly trued and cleaned up wheel set from the same bike should go with it. Something is not right though, maybe chain length, resulting in the small ring not being usable; fortunately I can wait till I’m home to figure that out.

I am just easing back into fiddling with bikes, and I am no expert, but I’m remembering how satisfying the whole problem solving process is. And having your wife tell you how much she loves the bike you fixed up for her is even more so.

40 miles today on my 1990 Bridgestone CB0.


Check out this unusual 4 seater now serving as gate art. I saw it on today's ride

After scrolling this entire thread, I am loving these setups! I'm currently building a '93 Trek Antelope 830 and wanted more of a "Cafe Cruiser", "Comfort" or "Dad Bike" instead of the traditional rigid MTB. I decided on a 1x9 drivetrain but still needed the perfect handlebars. Starting with some 620mm wide, 6 degree sweep, 30mm rise bars, they were just to straight and didn't seem right for the bike. Looking through the forum, this post by Smokinapankake really got me interested. The handlebars looked great and I liked that they were Bontrager, associated with Trek. I was surprised that the bars were only $20.99 and could be ordered through my LBS (no shipping!!!).

Yesterday, I got a call that my order had arrived and I was able to install them last night.

Specs are: Bontrager Satellite Trekking handlebars, 610mm wide, 25.4mm clamp, 50mm rise, 35 degree sweep, $20.99. Product link They also come in black.

While the build isn't complete, I'm really happy to see this integral piece installed. I will post the end product when the bike is done.

Original 620mm, 6 degree sweep, 30mm rise bars with 120mm stem


From the top, swapped to a 130mm stem. The bars bend slightly forward and then sweep back. The hand positioning is nearly the same but the sweep has more comfort.


50mm rise


Controls are complete using Bontrager Satellite Trekking handlebars, PNW Components Loam Seafoam Teal grips, Sunrace SLM96 R9 thumb shifter, Dia-Comp Power Control 7 brake levers and a black bell.

That's a really nice build.

I've had 3 different Trek Antelope mtbs I've built up similarly.

They make great cafe cruiser /Urban bike builds.

Enjoy.

The Schwinn Cimarrons are such cool bikes.

I've had a couple of them over the years and really liked them.

Both were 23" frames and were a bit tall for my likes so I moved them on.

Maybe 4 years back I bought a 22" 1988 Cimarron with really rough black paint and stripped the parts off.

It's been setting all this time waiting on me to decide what to do with it.

It is the model year they had the rear brake post braze ons under the chain stays which I don't like.

I was itching for a new bike project and finally got it together last week and and took the frame to a local powder coater.

I decided on a really different color... metallic yellow!
The original fork is all chrome so I'm leaving it chrome.
I love chrome.

I'll post pictures in a couple weeks when I get it built up.

Here's a rebuild from this summer. I wasn't sure if the threadless headset disqualified it from this thread; best I can tell it's a 2002 Marin Madrone Trail, 20" (seems like it was an overseas specific model that made its way back here). The brushed aluminum frame is what caught my attention when it popped up locally. Built as kind of an ATB rather than a super practical bike but I love the ride.
