Can't you just use bar-end friction shifters to fulfill your flat bar needs?

Yeah, though it might be more instructive to call them thumb shifters? Specifically if particular models can't swap mounting formats.

Maybe he just likes them more, maybe he just wants to do some bespoke poo poo instead of solving his problem with a spreadsheet :shrug:
Part of the reason to use a spreadsheet, or perhaps put less dismissively, to fully think through all the complications of the upgrade, is that there's real compatibility issues at play, as you just worked through with Tobin.
This is still my go to reference for ratio / cable pull numbers for various drivetrains:
http://blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/
It captures in precise numbers why some hacks work (like pairing SRAM 10spd MTB RDs with big capacity to SRAM 11spd road shifters).

As you can see, the 11spd stuff is not exactly the same cog pitch from brand to brand or MTB vs road, but it works ok in practice (I never got Campy 11 cassette to work right with Shimano shifting).
12 spd isn't even on there cuz the article is dead. I'm emailing Sunrace support right now to double check that their 12spd RD is in fact Shimano compatible, which means I'm out of luck with my Sunrace 12spd shifter, which is SRAM compatible.

quote:

I don't see how buying an entire bike is cheaper than a pair of levers, a pair of MTB shifters and some cable stuff.
Let's say the current bike is 11-spd. You'll need a $50 shifter. $40 for a ratio changer to go from MTB to road cable pull.
Maybe another $30 if you want to keep front shifting. $20 of housing, and cables if the shifters don't come with.
$25-100 for however nice you want your brake levers to be.
$60 for a flat bar and stem to get the geometry to match. $20 for decent grips.
And then, what, maybe $150 for a shop to do the swap for you if you don't know what you're doing?
Maybe around $400 total? With $50-100 from resale of the swapped parts to sell on eBay over a few months (or never, in my case).

It's not necessarily an apples to apples purchase.
You can still find totally decent flat bar bikes in the high hundreds. They're probably gonna be a step back from 11spd, but they might be hydro, which would be a real step up in some ways.
Sell your road bike and you'll probably be at or below the total outlay of the swap.

Who said anything about a chain ring...? What?

I wouldn't refer to cassettes as "1x" . You doing so was confusing. You can run Shimano MTB cassettes and such as 2x (even 12 speed).

I'd refer to the chainring up front as 1x or 2x because that makes a lot more sense.

Ok but what if he really likes his current bike, or is just stubborn, or whatever? When I say doing things by a spreadsheet I'm referring to boiling everything down into cost/benefit as opposed to just doing dumb stuff cause you want to.

I will admit the idea of paying people to work on a bicycle never occurred to me though.

If they can afford it, it’s no problem. But expense came up. Woe be if they come up short halfway and need to spend justs much to fix issues, leaving them without a bike for that much longer.

Paid for a Retul fit with a top rated fitter here. 1.5-2 hours of fitting and :homebrew: boiled down to:

1. Raising my seat by 5mm.
2. Tilting my seat back by 1 degree
3. Putting a shim in my right shoe.

Can't wait to ride a pass tomorrow!

Running without brakes on streets is dumb as hell. They aren't on fixed gear track bikes presumably because that's a good way to start a pileup in a velodrome. It doesn't make it some necessary part of riding without gears.

It’s hard for me to be overly critical of brakeless fixed gear riders when we just went through an episode where someone completely ignored all advice on how to actually stop on a bicycle with brakes, then forced a bike shop to swap the brakes around for a really dumb loving reason.

The term unsafe at any speed comes to mind. Or maybe unsafe at any acceleration.

Thanks for the suggestion! The way up involved only one group of assholes (with Illinois plates) yelling, but was otherwise smooth sailing. I thought I'd be fine in a short sleeve jersey since it was supposed to be 60 in Denver, but ended up being a bit chilly on the descent. :v:

The rear disc on my friends tandem was in bad shape. We bought a whopping 220mm disc. I placed it on the back wheel, the hope adaptor rubbed the disc, I ground it down untill it cleared, the caliper fouled the adaptor one way round or it was impossible to put the mounting bolts through the other way round. So I put the old front disc on the rear and put the new disc on the front with the adaptor positioned so the brake pads were over the disc the brake caliper fouled the adaptor. I turned up a couple of spacers on my lathe and three hours later I was ready to adjust the brakes.

I took my bike to the shop after I halfassedly put it back together out of the box (I had it shipped back to me from a vacation) to have them do it properly and found out I need a new headset and the mechanic loudly made fun of me in front of the whole store.

I recommend it. Great support, fun atmosphere and a decent route. Only downside, a bit of the route is paths and frontage roads along 70. Not super exciting.
