Does anyone make a singlespeed-type gravel frame with sliding dropouts? Thinking of building a bike with a Rohloff internal hub. Using such a frame would eliminate the need for a chain tensioner, as would be the case with converting a "normal" frame.

Find a Surly Steamroller. They work fine for this


Also an old Raleigh pre 74.

Wabi also has a gravel type SS.

I think a Wabi Thunder would be great for this. It will accept up to 45mm wide tires. https://wabicycles.com/products/wabi-thunder-frameset

Surly bikes are FFF Fatties Fit Fine so make nice gravel bikes and they have several nice SS models

One of the problems with finding a SS gravel bike is there are no cable routing/points to secure cables/housings for things like a Rohloff, bring on the Zip ties!

WOW! It even has mounts for cantilever breaks! (Can't tell you how much I hate disc brakes.) Definitely a top contender, if the canti's allow for 45c tires.

I know. I already built up a SS hardtail MTB frame with a Rohloff.

The Wabi Thunder has a minimum 45mm tire width clearance and some customers have fit up to 50mm wide tires according to Wabi.

Cinellli makes one ^

Crust Florida Man ^^ -- if it were not for their choice of marketing scheme, I'd get one. Probably.

And I'll second the SteamRoller - mine w/ 650b wheels and 43mm tires. If you run a front disk brake and fixed rear wheel, you can go 48mm tires w/ 650b



all these frames are 120mm rear hub spacing. Is a Rohloff 120mm? . . . i'm too lazy to google it. it's the cold / snow / ice - i'm going driftin' to . . . hibernat.......

post script - i added the cable stops to the TT. I also added a second set of bottle cage bosses. i was going to add fender eyelets, but there's just no space for a front - full - fender. and it's a SteamRoller - minimal mud guards at most, in my opinion!

I have been a Surly fan for 25 years, the Cross Check was the first bike I put enough miles on to wear out parts. This State Warhawk is my go to bike the last few years. It was amazingly cheap as a complete bike. The fit is good and the ride is smooth. The complete bike when I bought it was less than a Surly or Soma frameset.

Hate futzing with canti's. I'd go mini-V's. I've also had good luck with travel adapters.

Poseidon FX (I just picked one up with FSA funds) for $200 shipped. Not pretty (welds, weird chainline) and only reasonably accommodates a front brake but it's cheap, relatively light, and will likely fit 45+mm tires. (Disregard, didn't read the initial post properly)

I was looking at the salsa storm chaser, but it's a bit out of my budget. Has sliding dropouts.

What about an eccentric bottom bracket? It would help give you more choices for the frame used.

I have this 8 speed Shimano igh Raleigh Grand Sport

Here is a pic from the build.
I might sell it.

ALL CITY COMP

why do you hate disc?
I've never heard anyone say that before.
Personally I think disc brakes are amazing

why I don’t like disc brakes
​​​- adds / requires more structure to the frame and fork
- makes a flip flop hub infeasible…. This is the single speed/fixed forum.
- adds complexity that doesn’t improve anything. Properly set up brakes will lock up wheels just fine. Improperly set up brakes won’t, disc or not.

why I hate them
- encourages/enables bad trail behavior, like riding when trail conditions are muddy and wet. If you have rim brakes you’re less likely to ride a muddy trail so you don’t grind up your rim.
- gives unskilled riders a sense of unearned confidence leading to stupid crashes. But great short videos!
- I think it’s going to lead to e-braking soon. You’ll have to have e-braking ABS or you’ll DIE!! That’ll be the marketing. And the bike will be more complex. Harder to work on. More expensive. And the off shore companies that sell it cheap will
make it very dangerous.
it’ll be funny though when the early adopters find out that the lawyers require the brakes to lock the wheel if the battery is dead. That’s how we’re doing it in the automotive world with electric brake boost and electro mechanical brakes.

where I would use disc brakes
​​​​​​- a tandem maybe. Especially if I lived in the mountains. I guess they still use drum brakes and drag brakes.
- If I had the self discipline to limit myself to one bike, and I wanted to run radically different wheel sizes. Like day a Jones Bike.
- If I was a frequent foul weather commuter.

To follow up on what mrv said:

1) Disc brakes don’t work with track dropouts, because the wheel can only be in one position relative to the caliper which is mounted on the chainstay. With rim brakes, the brake pads are moved up or down to align with the rim as the wheel position is adjusted in the dropout to achieve the proper chain tension.

2) Disc brakes are a lot heavier than rim brakes.

3) You have to place a wedge in between the brake pads when transporting the bike with the wheel(s) removed, otherwise the caliper pistons can be pushed out if you accidentally depress the brake lever.

4) Most disc brakes are hydraulic, and setting them up requires bleeding air from the brake lines and properly filling the master cylinder reservoir with brake fluid. Also, if the brake lines get cracked or damaged for any reason, you instantly lose all braking function.

Interesting.
different strokes for different folks.
I think disc brakes are great.
I do not like rim breaks

new albion privateer is like a cheaper better surly cross check, mostly because it's got a reasonable stack.

My Surly Pugsley has track ends and disk brakes.

…and what’s the free/free flip/flop hub look like?

ps..... hmmm... .too snarky.... i should delete.

anyways - I like Surly. It's like they ask the question: "why not?", and then ignore any answers they might think of.
A free-wheeling Krampus or LowSide look appealing. I've not been able to convince myself I'd spend enough time on them to justify the cost -- so I'm spending a couple hundred bucks on a Roadside Rescue RockHopper. Not a wise use of money that could go towards the retirement or mortgage. But hey, the LBS-owner has to eat!

OK, so it looks like the disk brake caliper is mounted on the left seatstay instead of the chainstay. Still, there is only one optimal position for the wheel in the dropout. BTW, Surly no longer makes the singlespeed version of the Pugsley.

No flip flopping with offset wheels. Front and rear are the same so you can have front and back set up differently if you want. I had 2 different cogs on it for the first year. Then nine speed with single speed front for bailout. The derailleur snagged a rock one day, mashing track end closed. Took it in, and mechanic found frame cracks at all the welds. Got new frame barely in warranty time. Then I tried the Nuvinci rear for a few years, Broke 2 of them. There was a 27.5+ takeoff wheel from something in the back room of the shop when I took it in with the second Nuvinci failure. We dished it over without having to change any spokes, and that wheel has been on the back with a 10 speed ever since.

Surly slots the brake mounting holes so you can adjust the disc caliper as you adjust the wheel.

I just bought a dead stock all city super professional. They have a sliding dropout system that will allow you to get proper tension for a 1x1 setup. Also fits at least 45mm 700c and 47mm 650b.
