Interesting. I did not think the quill could take a 55. But even that is a far cry from my 2.6” tires.Regarding the dynamo - I got a nice deal on the wheels & envisioned some possible nighttime adventures in addition to standard MTB duties. So far it’s been exclusively MTB - nothing at night.Sent f

that dynamo is about 170g heavier on average, if I'm remembering

To pile onto the bolt-gram-counting-train, Paragon Machine Works is having
a holiday sale and you can get some nice M5 and M6 Ti bolts for about $1-2
each. That falls under Bill's $1/g (approximate) limit. Bonus for being
local!
I picked up a few for fender mounting and to save some weight on t
In my original post I said: "The bolts gives (sic) the opportunity to do

up on my CHG build.

El Cerrito,
I almost forgot. The wheelset I kind of fell into (Cliffhanger’s) came with a Son dynamo hub. I still do not own a dynamo powered light two years on. I think it’s a relative boat anchor? So yeah, an alternate wheelset might make a difference I would notice. Lastly there is the Silver double crank v

Fair points. FYI, the Susie is (I think?) 8 ounces lighter. If I was truly concerned I could shed the B17 & steel Albacore handlebar for instant weight loss, but I love both.Sent from my iPhoneOn Dec 3, 2024, at 12:29 PM, Bill Lindsay wrote:A gram-shaving Gus build sounds to me like a Susie build

when the tires get that wide, that's where we switch over to disc brakes,

Sure, feels a bit snappier off the line and surprisingly fast for an
upright bike (nice tires with light wheels mostly help here). If you get
really active with the bike, go for a spirited sprint, or chuck it in some
turns at an aggressive speed, the weight shift does feel more noticeable.

518g = 1,188g Now it makes sense. Did you double-count the front wheel

I don't follow the math. The rear wheel math makes sense to me:
Heavy old rear wheel weight - Lighter new rear wheel weight = rear wheel
weight savings
2252g - 1582g =670g = 23.634 oz (checks out)
Heavy old front wheel weight - Lighter new front wheel weight = front wheel

Rounding out the build plans there are sections 4 and 5. Components and

I don't think so. In some sense it's purely a physical exercise, removing

Thanks for taking the time to lay all this out, Bill. I have last year's

Hi Joyce
There's an immense backstory at every single piece on this build, and I was
going to meter it out one section at a time for that reason. One of the
fun backstories is that my old college roommate has asked me to set aside
2+ weeks in the Summer of 2027 to do a Loire Valley cycle-tour.
Bill,
This series of build descriptions is of great interest to me and so timely
since my Charlie Gallup has been shipped. I appreciate your strategy
explanation and it's helping me think about my own new bike. I'll have my
