L-twoo hydraulic calipers with 180mm rotors at the front?

[lantz]

I think it's going to work.
Current setup on fork is ltwoo 160mm (using ltwoo hardware from the box).
the adaptor says 160 to 180mm.
Using longer screws, the adaptor goes between the fork and the existing setup as pictured above.
None of the holes in the adaptor are threaded, so it's really just a spacer, someone courageous enough might just put shims really...

So, the current setup is threaded into the fork at 70mm interval. I'll add the adaptor, using longer screws. And voila. In theory.
On the picture here, the 34mm spaced holes will not be used. I guess that's to screw on a shimano FM caliper, at which point i think you have a 160mm setup, not 180. Anyway, i dont run shimano.

That sounds simple, but it took me over a year to find that stuff at a reasonable price (12 usd + shipping). It should cost 4 bucks, but hey ho.

May have found another version more easily obtained here at Amazon: https://www.amazon.com/LQ-Industrial-Bicycle-Accessories-Hydraulic/dp/B0CNJZGDLY?source=ps-sl-shoppingads-lpcontext&smid=A23QJEODOLCAYG

or even: https://www.amazon.com/dp/B09SH8FV9M?content-id=amzn1.sym.8c2f9165-8e93-42a1-8313-73d3809141a2&s=sporting-goods&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw

Am I crazy or is these the same?

Well I'm in Europe, so can't buy your links, first of all or import and what not, too much drama.
The first link makes no reference to 180. I'm a simple man, and I've already bought adaptors that didn't fit. So, I think the first one doesn't work.
The second one makes a reference to 180, but it's confusing.
So... My source is selling them for 12 dollars, I'm buying 7, and a friend is paying for the shipping because he wants his upgrade in winter... So I'll buy from my source, I think. But it doesn't mean there aren't alternatives. What I know is that I've been looking for months and never found anything that worked.

Of course, yeah. Curious what other options similarly you've tried so I can avoid them!

I ordered the first one because, it's 20mm, fuck it, lol. A lot easier to get 2 day shipping than have to email someone to order a single part, but as soon as that one doesn't work, I'll be going for the Lewis one, haha. Appreciate you sharing!

What is wrong with XLC BR-X106 & BR-X107? I ordered them few days ago, still on the way. Found them due to somebody's conversion fotos..

That does look like ti'll do the job. I got the other one I posted today, I'll play with installing it tomorrow and see if it works!

I don't think they work with ltwoo calipers. They probably work with Shimano ones. Looking at the front one only.

Hate to rain on ya here Serge, but the adapter i got form amazon is almost 1:1 the same as the lewis, but it doesn't work and the reason is really annoying.

The L-Twoo calipers have this bulge that goes down into the adapter they offer - that works in that gap in that adapter, but because "flat mount" standard is literally meant to be *flat* against the adapter or fork, you lose the lift/benefit of this adapter when you install it because the caliper isn't direclty mounted to the lifted part, it's mounted to the outside areas that don't give the full 20mm lift.

It's midnight here, but I'll try to sketch it out tomorrow to show you what I mean. Essentially, the little ridge that hosts the 34mm spacing is where the Shimano caliper would attach, giving it the life, but you're bypassing that with the l-twoo brakcet and going back down to a smaller lift, which doesn't *quite* do it. I was *almost* there, lol.

Same with the Magura posted here - almost *every* "flat mount" adapter tha'll get ya 20mm, the 20 mill is on the highest edge of the rise where the Shimano would direct mount, and as such, does us no good.

I did try to just use the adapter between the caliper adn the l-twoo braket, but because of the odd shape of the l-twoo caliper, the little buldge made it impossible.

You guys should either switch to GRX calipers or in my case use a gravel fork with a mount offset for 180/160mm and not 160/140mm (like this EVOSID gravel fork). 180mm front rotors on a gravel bike is a game changer. I took my gravel setup on some steep mountain trails the other day and the difference in brake modulation is very noticeable. Less pad wear and heat build-up.

I'm definitely not going back to 160mm in front, at least for gravel.
