Random questions

1. Are there any old 4130 or better roadie's that came with disc brakes? Is the introduction of disc post introduction of aluminum frames.

2. What is the highest sprocket count for rear cassettes on steel road bikes of the 80s and 90s? Highest I've seen was 7 for a 14 speed bike.

3. Are there any 4130 or better road bikes of the 80s and 90s that came with vertical dropouts?

#3 - Yes there were many. Take a look at the Specialized Allez as an example.

Disc brakes (current appearance) started with off-road bikes with suspension. Let’s call it 1990’s.

8 cogs in back began in the 1980’s. Really required a freehub to avoid bent axles.

Campagnolo 9-speed was introduced in 1997, 10-speed in 2000.

Discs + road didn’t really come till deep into the 2000s.

Discs + Decent-Steel Road has been a thing since about 2010. A lot of brands had at least one, often times it’d be made of Reynolds 853 with a carbon fork, some brands like All-City were pretty much just “Decent Steel and Disc Brakes” as their niche for a few years.

Surly Disc Truckers are 4130, I think.

2) the 80s OEM maxed at 8 speed, 90s was 9 speed mostly then 10 toward the end. Any 130mm rear end can take an 11 speed cassette.

3) seems like most okay-to-great frames were vertical by 1991.

Nice.


Another random question. Did Schwinn make any split tube cruiser or single tube klunker in a quality tubing? Or were those bikes like the VW bug of the early bike area. If not what company of bike series would you consider to that.

After recently learning more specifically about tubing and different joining methods and frame charactistcs in general. I'm looking at my dads Chicago Schwinn like 🥴

I mean, there were quite a few ‘83-90 MTBs from different companies made of Reynolds, Tange, True Temper, and Ishiwata tubing, some were lugged, all can be equipped to fit your vision of what a Level Top Tube Klunker would look like.

The only one that I think Chicago Schwinn did was the Paramountain Ned Overend.

for curvy tubes but good riding, the first thought is Ingliss/Retrotec. A few hours/days surfing cycleexif and radavist might turn up some others.

I think it’d be cool to throw $1500-2500 in parts at a Walmart Beach Cruiser to make it both trail worthy and look like a 70s downhill racer.

I mean, yeah, but I see a lot of Wal-Mart beach cruisers at the co-op. The joints of a Walmart beach cruiser from the past 10 years or so are not likely to hold up under the stress of bolting new pieces on, much less going downhill fast. I guess you could buy 100 Wal-Mart cruisers and test to find the one that was made right. As Yogi Berra said, in theory there is no difference between theory and practice - but in practice there is.
