Surly release new hub standard

145mm rear end.

Put the pitchforks down. It’s a steel frame, will stretch.shrink to fit 142 or 148. And they even include wee washers so you can fit 135 QR too.

Has anyone any experience of the newer Surly dropouts? I had a Karate Monkey 6 years ago that was a PITA with the horizontal dropout + mech hanger combo. This seems to be making things steadily worse….

Good colours though. 🙂

I thought it was genius as you can fit both hubs? How is this a bad thing??

but it doesn’t “really” fit does it – bending your frame doesn’t sound like a proper engineering solution

How is this a bad thing??

Worst case scenario wheel re-seating after fixing a flat:

– 135mm – bollocks, I’ve dropped the fiddly spacer thing and it’s dark;
– 142mm – bollocks, the thing’s so loose it keeps shifting around when I try to do it up;
– 148mm – bollocks this is really tight! There are paint flecks everywhere and I just know I’m going to manage to break a tooth trying to get this in…

😀

I mean, it’s a game try at accommodating people who are struggling with standards fatigue. It just looks a bit like a bodge. And (as I said above) those dropouts are pretty annoying to start with.

It’s only covering a 5mm difference, 2.5mm each side, or 1.25mm of movement. I’ve had frames with more paint on them than that.

Looks like you can slide the wheel in from underneath then tension it, which is actually kinda genius. Although I can’t see how you could fit a chain tug, which make fine adjusting chaintension so much easier than guesswork.

its not that new an idea. My 6 year old crosscheck has dropouts that are spaced at 132.5 to allow use of road or mountain hubs. means i can use strong and heavy touring wheels, or drop in nice light road wheels for diffrerent uses.

Ah! That is new, and, if true, genius. Good. 🙂

Wonder how long it will take on-one to sue them, most frames of there’s had this, I mean not intentionally but still… 😆

I think you could probably have squeezed a 142 rear into my 135m rear 224 evo, pretty springy-outy rear end

Cotic roadrat has done that with 130/135 for years too. Really not sure I notice it being any harder to use.

As mine is at least third hand to me (Northwind had it last) and hasn’t cracked yet I suspect there are probably no long term problems

Forgot about that! How is my poo bike btw?

Ticking along nicely- two and a half years of commuting and it’s still going steady. Back on drops since christmas after two years on flats, and it’s currently got gears again as I used it to go touring in France a couple of weeks back. Wtb nano and woodchipper bars make it very fun!

As for the colour, well, it’s still ‘espresso’ but at some point I have been thinking about getting it repainted in that nice grey colour the new ones are coming out in. Possibly get some forks to match so I can run a dynamo.

well, meh, I wouldn’t have it but fair enough…
However why do we need ANOTHER new axle standard? Fair enough make the dropouts 145mm…but then surely you choose either a 142 or 148 hub to put in it!

Making a 145mm hub just smacks of “well, we have done this thing to cover all bases…but it turns out we cant look at it now cos it just looks like we haven’t built it properly… so here’s another new axle standard”

EDIT – or is there in fact not a 145mm hub…?

Err..? They are, its not a new standard.

hmm yeah – just realized that might be the case
harmony restored then 🙂

Top quality ranting while missing the whole point. I tip my hat, sir.

A more accurate thread title would have helped 🙂

Surly have been doing that for years without problems. 132 rear ends so you can fit 130mm or 135mm hubs for example.

It’s one of the benefits of steel, it may be gnot-rite, but it works. 🙂

My Van Nicholas Amazon has 132.5 mm dropouts too.

I know someone who (briefly) fitted a 142×12 wheel into a 135×12 YT wicked by mistake

*cough*

You’ll have to post up a picture before I believe that one. 🙂

I’m someone who bought a 142×12 hope axle from CRC, fitted it to the wheel and then the bike.

Wondered why the thru-axle needed so much doing up as there was a gap at either end of the axle and the axle thread bottomed out before the wheel was tight in the dropouts.

Later found I’d been sent a 135mm axle in a bag with the 142mm part number sticker on it.

Was a friend’s bike. We’re still friends.

Not much of a bike tart, but have you seen the Karate Monkey in purple?

B+ or 2.5*29.
I’ve no intention of buying a new MTB until the old one breaks, but if I ever did…..
This and the new Cotics seem to fulfill all my MTB bike porn fantasies for a while.

The geared one is bright yellow.
I could live with that
🙂

Interesting to see what they’ve got planned for the 29+ers.
All the braze ons of the ECR on the Krampus frame would be nice.

Maybe they’ll drop 29+ completely?
The ECR might continue, maybe the Krampus as frame only?
All with the new drop outs I assume?
ECR has a low BB drop as it is, it would need to be redesigned from the ground up to accept smaller wheels.

Interesting times.

at least they found a new name for it…
gnot boost spacing… 🙂

The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost™ will all work in the Karate Monkey frame

On one/planet x have taken the concept one step further and applied it to seat tubes.

Nobody’s ever accused me of being astute before

Surly Introduce 145mm Hub Standard?!

Was skeptical of the horizontal dropouts as they’re a pain if your run gears (which most of us do) but they’ve positioned the hanger correctly- it’s terrible on the CrossCheck as you have to put the wheel right at the opening to get a half decent gear change. Would love to know if the chainstays are shorter than on the old KM Ops. 430mm with clearance for a 2.2 tyre would be nice.

Simple and effective idea.
Can see more frames going this way from sone of the more customer focused companies. Should work with other materials as well I’d have thought… only ±2%.

Adaptors are out now. Basic tophat style spacers to change the 142 to 135qr.
