Those are Maxxis Hormworms 20"× 1.95" and I run them at 80-90psi and they kick ass! They are however kinda heavy 720g each but they make my bike turn like it is on rails.

I got the cranks off amazon on an overnight price drop for $116 they are sweet.

Chaadster,

I did the 11-32 /56t and gained 11 gear inches. (84.1 to 95.1) It mattered a lot. With a 60t you will be at 101.9.

That will be badass.

Good luck with the knee

Thanks for the well-wishes and the link. I'm familiar with the calculator, though still not that sharp with it; I get GI, but prefer the 'speed at rpm' output. Gain ratios make sense in theory, but I'm too daft to put them to practice!


I wound up getting a pretty 'corn cobb-ish' 11-23 (8sp 11,13,14,15,17,19,21,23) Origin8 Pro Pulsion cassette because it was cheap and shiny. I don't know if I'll miss the 12t cog or not, but usually when I'm on that one I'm going for the get-away speed anyway (as opposed to just cruisin'), so it'll probably work.


I haven't ordered a 60t chainring yet; finding affordable black ones was difficult, but there are some Driveline brand ones on ebay right now that I will probably order soon. They've got polished highlights, too, so should look good.

Chaadster,

Speed with RPM makes more practical sense that is easier to relate to. Considering that's why I messed with the gears, I could never keep up with the "big tire" bikes and was pedaling like crazy when the others were not. Thanks.

I think I got a big chainring from www.hostelshoppe.com and might be a Vuelta, (I've upgraded the gearing on a Downtube FS9 a few years ago).

Just as an informational follow-up, I think the Origin8 Pro Pulsion cassette is crap. I installed it yesterday, and after futzing with the derailleur to no end, I just can't get the second smallest cog to pick up the chain consistently, and when it does have it, to stop grinding noisily away at it.

I don't know if it is a spacing problem or a tooth profile problem, but I even took it over to my guy at the shop (big up to Casey over at Tree Fort!) after failing to getting it running right, and he couldn't get it to work either. After discussing pulleys, chains, checking hanger alignment, double checking cable housing and lubing everything up, we concluded it was the cassette; everything was running fine before I swapped that one in.

I'm going to try to frankenstein the fix by mixing the the older and new cassettes to see if there's a combo that shifts well but still allows me to run the 11.

I'll keep y'all posted.

Woah! That's a fantastic build on the Bully. Well done! :thumb:

Of course, it's begging for a set of Shimano hydraulic brakes...

Thanks.

at some point I will probably go for hydraulic brakes but I was thinking of Magura brakes in part due to the limited real estate on the narrow bars and their levers I think would fit a little nicer that or I have to try and fit a banjo fitting to a shimano lever

So, that Origin8 Pro Pulsion cassette is a piece of crap. I didn't try a different chain-- and I acknowledge that the stock Sunrace is itself a POS-- but I did try swapping in the stock 13t cog without much improvement, and settled on, ultimately, just using the Origin8 small 11t cog and lockring on the stock cassette in place of the stock 12t and lockring. It restored shifting performance (well, not the lockring), so I'm happy about that.

I remember the improvement in shifting when I went from freewheels to my first Hyperglide cassette, but haven't thought about cassette performance in the intervening 25 years. Lesson learned, I guess.

By the way, has anyone run a 9spd chain on their Nano or other 8spd cassette equipped bike? I'm wondering if the narrower width will help mitigate the awful chain line when crossed over...and the KMC in gold would be pretty jazzy!

Very nicely done.

Tuff!

The blackout treatment looks great, and I bet those wheels were a real improvement over stock. I'll probably do wheels on mine over the winter; those are Velocity A23 MSWs?

thanks, its a velocity aeroheat. couldnt be happier with this build.

Did you ever get an answer on the chain?

Me? About the 9spd chain on the 8spd cassette? No, not here, and I haven't talked to my mechanic yet about it, but as winter arrives, I'll start getting into some bike projects, so we'll see.

I love the bike ....AND.... I love that Bertoia chair!!! The modern magazine rack is nice too. Also, I have that same dark brown Expedit bookcase, except mine is full of records, not books.
(OK, I'm done stalking your photo now.) :thumb:

I think everyone on earth has one of those Expedit bookshelves, good eye on the Bertoia I just wish I had the original cushion for it the only really nice modern furniture I have is that chair and a small Saarinen tulip table.

Funny enough this bike also has velocity Aeroheat rims but in non-MSW because of the disc brakes(it actually cost me more)

Well, I did a 36 mile ride with the bike club a couple weeks ago. My neck hurt for a week. So, I decided to put on some handlebars that were sitting around. I'm 6' 240, so I was always a little cramped with the drop down.

I took the old bars off intact in case I wanted to switch back. But after I tested it on the BaltimoreBikeParty last week ain't no way I'm switching back.

If there was supposed to be a picture there, I don't see it.

^^^Needs metal-flake paint and a banana seat.

I'm curious what your reasons were for going with the Origin 8 cassette (over Shiman, SRAM, Campy, usual suspects, etc.)?

Is the Origin 8 cassette very light, or was it price?

As I said above, I went with it because it was cheap and shiny, but I think I was having a hard time finding any 11-23 8speed cassettes.

I've got the 60t chainring on the way, so I'll see how that does me.

Nice! I agree that you need a banana seat. :)

You guys reminded me. I have a banana seat up in the rafters of my garage. Once had it on a huge Schwinn varsity (along with hi-raise handlebars). Hmmm.

So, I got the Driveline 60t chainring on the bike, and coupled with the 11-25 cog set, I think I can now roll at the speeds I want! I've yet to take it anywhere beyond around the block, so nothing definitive yet, but initial impressions suggest I've got a good working range off the big ring now. The 44t inner is still in place, just in case I meet a mountain. :)

A word on the Driveline: it's not a performance item. It's a hefty chunk of alu, nicely detailed with the machined/polished cutouts, but it's not pinned or ramped, so shifting is old school style; gotta slow cadence and ease up to get the chain up on and on. The old 54t Origin8 was very sweet shifting, so this is a step backwards in that regard, but the fact is I'm almost always on the big ring, so front shifting quality is not so important to me. Still, it would have been nice to get a quality 60t that looked right and didn't cost more than a third the price of the bike!

Hopefully I'll be able to put it through it's paces this weekend. Here's a pic:
