RidingAgain

I've got a few kids riding jerseys... Smaller sizes... Maybe for kids 4-8 (I'll have to check the exact size and take photos)... All in excellent condition... USPS and Texas Race Series print. I'm in SW Austin, near where 290/71 and Mopac intersect. Just going through my stash to see what adult jerseys I have to list for sale online and thought pay these forward.

2018 Transition Sentinel... Black... Contact Donovan Miller on Facebook if you see it...

Lots of good info/advice... Thanks, I appreciate it. I'm going to breakdown the North Star today and see what's what. I'll post photos.

Are you going to try and disrupt this thread too, ATXZJ?

I've got a few 26" rims with cassette hubs... And one with a freewheel hub... How difficult is it to change these to a dedicated SS set up? Will it require a new wheel build?

Yes... Pretty sure it is.

mack_turtle... Gotta check cranks... But components are XT/XTR mix. Shifters are not integrated. I'm good with just building something that works. It won't be for me as the frame is too small (actually all the frames I have are too small). Was considering a 27.5 on the front, 26 on rear to slacken the geometry some. Looking at it I'd say that the HT angle is in the 71° range.

I picked this up at Yellowbike... It's just one of the frames I have that I can use. And it's very light. Maybe circa 1992. From what I could find out, it seems that North Star was made by a small company in Colorado, but there's really little info on it.

Another question... Aluminum or steel frame... I rode steel with a cassette for some years and know the feel is completely different to aluminum. Is this difference heightened with a single speed set up?

Thanks... Appreciate it. There are two cogs for sale on craigslist... One is an 18t, the other a 16t... I was thinking the 18t... https://austin.craigslist.org/bop/d/austin-cog-and-lockring-18t/6968197555.html https://austin.craigslist.org/bop/d/austin-cog/6957194347.html

So I've looked at numerous videos and read comments on forums... I'll be using a cassette hub and I'm clear on the spacers/chain line requirement... But have read different thoughts on the chain tensioning. Dedicated chain tensioner... Half links... Old derailleur... Just wondered what SS riders here have to say? The bike will be mtb with a hanger. Thanks.

Thought this series from Seth was interesting and related...

I'm thinking that the G-string rider must have thrown ATXZJ into a tizzy.

And now we know what ATXZJ looks at when participating in group rides.

"...Where's the sweet spot..." according to your riding experience... As related to the big cogs that have now been around (being used) for a couple years now). Which is made clear in my first comment... "Just wondered, now that these big gears have been around for a while, what's the experience feedback on them?" And am I really interested in knowing what type of cassette everybody is riding? No... I'm interested in hearing the riding experience as related to the big cogs... Which is why I specifically asked about the big cogs... 40t, 42t, 46t, and 50t... Which, again, I made clear from my very first comment. Regarding what you ride... So are you saying that riding a bike with a 36t cog or a 50t cog (if your bike came with one) makes no difference to your riding experience? If so, you'd be the first person I've come across with that feedback.

That's kind of obvious from the phrase... "sweet... spot...". But the actually topic is... What's your sweet spot (experience)... Not what is a sweet spot. And for sure... The more cogs (as long as they are closely related size wise), the smoother the transition. But we should know that in the beginning of 40/42/46/50t trend (which is the thread focus) the jump wasn't — and for some still isn't — that smooth. Have you ever found yourself caught, in a manner of speaking, in between gears in a situation, instead of just staying in the gear you're in and using power to do the job? Shoot, that would happen with me when I used a 7-speed drivetrain.

Okay... But how about that chain guide?

Is that a chain guide on Trek's new bike... https://www.singletracks.com/blog/mtb-news/unreleased-trek-full-suspension-mountain-bike-spotted-at-uci-world-champs-this-weekend/?fbclid=IwAR3e0rx-WyHKpec6lhxjCQP6WmnKJbJNh1EyvPXPSRp4eChloqJccBwfxxo

Nice. Reduce. Reuse. Recycle.

For you... And others... But obviously not for those who would go to the length of a DIY 7-speed for their personal use. And therein is the context of personal "...experience...". I used to think that 580mm handlebars worked... Then 620mm... Then 680mm... Then 720mm... And now 760mm. And I just bought an 800mm this weekend. As I think ATXZJ brought up, it's got a whole lot of subjective involved. And I think that as overall bike design evolves, related things can change. Who knows... Some kind of new design chainring/crank combination may make a 7-speed the next best thing.

There was a comment by someone where he says he made a DIY 7-speed cassette (I think it was 7) from a 10-speed (I think it was 10) cassette using the larger cogs... Something like a 12/46 7-speed cassette. He said because of what he rides, he really only used 28-46, or something like that. Perhaps what's next for drivetrain design development are environment specific drivetrains. Then of course will come quick-change drivetrains. Which would go perfectly with quick-change geometry, fork/shock travel, dropper seat posts.

Preferred Ratio Tire Brand Man chimes in.

Saw this in a comment below the following article... Thought it worth its own thread. https://www.pinkbike.com/news/rotor-confirms-full-details-of-1x13-drivetrain.html

Oh, what the hell... Trump.

Maybe it's their preferred ratios.
