Additional to yesterday’s publish, after a 20-mile check experience the chainring swap seems to be successful:
Shifts to the so-called “granny” ring now appear to be constant and dependable, and as a bonus upshifts are a little bit smoother too:
Why is it referred to as a “granny,” anyway? Is it as a result of grannies are imagined to be weak? Or is it as a result of they’ve fewer enamel? Both approach, it looks as if grandpas are equally weak and toothless, and I’m tempted to say that going ahead we should always merely name it the “grandparent” ring. Nonetheless, triples are nearly extinct as it’s, so at this level it most likely doesn’t matter.
Anyway, see that bulge alongside the interior plate of the derailleur, adjoining to the chain?
With the smaller ring the chain was beneath that bulge. Subsequently, the derailleur needed to transfer farther inboard as a way to reliably transfer the chain off the ring, on the threat of dropping it. However with the bigger ring, every part appears to line up kind of the best way it ought to, so hopefully we’re all good now and that’s that.
So why use a triple on a street bike in 2025, anyway? Properly, for one factor, I already had all of the elements. (Okay, possibly I had to purchase the chain.) However extra importantly, I needed the Roadini to be the alpha canine in my kennel of street bikes, and due to this fact I needed it to have All The Gears–every part from teeny-tiny ones for scaling steep unpaved grades on summer time trip to big-ass ones for happening the opposite facet, plus all the standard street bike combos in between.
The fashionable method to attaining wide-range gearing on a sporty all-terrain drop bar bike is one thing like SRAM Purple ASSPLR:
In equity to SRAM, I do know you don’t must get Purple if you would like the newest wide-range gearing. However, I’d be remiss if I didn’t level out that their battery-powered distant management derailleur alone prices Seven Hundred American Enjoyable Tickets:
Setting that apart, firing up the Sheldon Brown Gear Calculator, right here’s the drivetrain on the Roadini:
And right here’s SRAM Purple ASSPLR with a 40-tooth chainring, which I consider is fairly typical, and their $600 ASS-tastic 10-46 cassette:
Not solely are the low gears nearly similar, however I’ve received a a lot increased gear too, which suggests I’m 100% assured to win a race towards anybody driving a motorbike geared up with SRAM Purple ASSPLR.
Better of all, I don’t even must plug it in!
Additionally, a friction shifter means that you can use just about any cassette you need whatever the variety of cogs, and in case you haven’t checked these days chances are you’ll be pleasantly stunned to be taught that 8-speed cassettes as of late price little or no. Presumably sufficient persons are shopping for $600 cassettes that the identical firm is ready to promote you this for about what a few interior tubes* prices:
*[An inner tube was sort of a bladder made out of butyl or latex that cyclists once used to keep air inside their tires.]
In any case, with the shifting subject (hopefully) sorted out, I’ll subsequent transfer on to brake curation:
The stopping energy with these rims is superb, however as I discussed, I’m getting a bit of little bit of squealing, and I’ve now tracked down what stands out as the final remaining ceramic-specific street brake pads on planet Earth.
Think about what I might accomplish if I cared about one thing that was truly necessary…
