Slingshot Stem on an 89 Stumpy Comp
Been fiddling with different stem/bar combos for this new to me 1989 Stumpjumper Comp & I really like the way this slingshot stem looks on the bike. The Stumpy came to me almost 100% stock, missing only the original turbo saddle, & will need a complete tear down & refurb. But I'm excited to get started.

New Build Thread: `84 High Sierra "Beer-Truck Bike"
This one definitely fits here. It's far enough along now that I can post a pic on this thread:

The build thread is here: $20 "Clang-Find", 1984 Schwinn High Sierra - Bike Forums
The pressure is on to finish this one before the snow flies. Ideally, I would like to shoot some pics with it loaded up, in a backdrop of peak fall colors.

Yeah, me too. I'm just not a fan of the Unicrown. Even though I know it is superior structurally to many of the lugged/brazed options, it still just looks like a bent piece of pipe to me. That said, I do have one on my winter bike, but then, that's just a beater anyway.

'91 Bridgestone MB-1
Picked up this MB-1 about two years ago. I tried it in its original configuration, but was never really comfortable on it. I thought about a drop bar conversion, but decided to go with an upright set-up. Glad I did! The Bosco HB's really bring out the best in this frame.

The Schwinn High Sierra turned out great!
You will be able to carry a bunch of stuff in style.
I enjoyed seeing the pics from your Tweed ride on the Where did you ride today thread.

I double checked the tubing sticker on my late 80's Miele Aries 650 mt bike set up as grocery getter.
Original Mountain LX derailers from were from around 1988 as I recall.
Decal does show CroMo tapered double butted Tange Infinity MTB tubing as does Smokeinapankake's Panasonic MC 4500 mtb.https://www.bikeforums.net/22514043-post913.html
No current picture but I switched basket to the front and have child seat in rear now for my granddaughter.
This bike does have pretty relaxed head and seat tube angles and rides great unloaded.
When I load up that front basket the steering gets twitchy.

Tire availability is always changing with new models coming out and hopefully new technology that improves overall ride quality, rolling resistance, flat resistance, etc.
I'm wondering what 26" tires folks are liking these days on these types of mostly street/urban riding conversions like in this thread?
I do like my Rene Herse Rat Trap tires but do not want to invest in another pair at this time.
I also like my Maxxis DTH's and am leaning toward another set of them.
My Tioga Powerblock's and Continental Contact Speed are pretty comparable in my view but I'd like a tan sidewall.
I generally go with a 26x2 or 26x2.1 or 26x2.15
or in that general width.
Most of the tires I mention weigh in the range of 550 grams give or take with the Rat Traps a bit lighter.
In the past I've tried some heavier tires in the 800 to 900 gram range and I can tell a difference.
I did not care for them and avoid the heavier tires.
Thanks to all.

91 Diamondback Axis



Current build in progress but rideable just not safely 😅. My first time with the Billy Bonkers and i can tell you this is a quick bike that pedals effortlessly. Not to mention the comfiest one in the stable.

I think I finally have my
Gary Fisher Hoo Koo E Koo dialed in.
It's comfortable, fits well and fun to ride.
I was able to get in 36 miles on it yesterday for a good test.
I really enjoyed the ride on it.

A number of years ago I bought a pair of Vittoria Voyager tires in 26x1.75, wire bead with a low thread count (not the Hyper that they advertised, but I understood that). $23/each. I put them on my Ross, which I was (and still do) keep at my family's house here in the USA when I was living abroad, and later a long drive away. They're great, and certainly for the price I still like them.
Looks like they're no longer available, like the Voyager Hypers on my touring bike. I'm on my last set of those, purchased cheap from an English website. I guess I'll have to figure out what's next...

My wife and I both got rigid mountain bikes back in the '90s and rode them as MTBs for years. When we finally upgraded to 'real' FS mountain bikes (and bought 'real' road bikes as well) 5-10 years ago I put 38mm road tires on our old MTBs and they became gravel/grocery bikes. Then a few years later I developed old-man disc issues, needed an upright riding position, and cobbled together the bastardized cockpit shown. The bike is actually in better shape than it may appear. After a drivetrain refresh last year (new chain and cassette) it runs silent and shifts smoothly - maybe now it'll last another 30 years (though I suspect I won't).
