Mondince new 2026 Aero Gravel

Just long and low for me.
I measured saddle-lever length from older bike. Can't take L-size. Headtube is too long.

I'm not surprised. I wasn't aiming for a low position but I've got one 5mm spacer on the medium. The 420mm forks do make a noticeable difference compared to my old cross bike.

[Japeke]

I really think that 395 and 420mm forks really change the way the bike handles.
I don't try 420mm fork, if there is not anything strange with 395. I have both.


Actually a bit strange if 395mm works well. That would mean you could also swap a shorter fork to mondraker arid too.

It's not that strange. The fork is 420mm because the bike is suspension-corrected. A small gravel suspension fork, when fully compressed, is right around that 395-400mm mark so the bike needs to be able to handle such a short fork.

[Japeke]

Hmm... You are right. Fox gravel fork ac is 435mm and stroke 45mm.
So ac with rider is maybe that 420mm. Full compressed ac is 390mm.

But why there is allways just one long rigid fork?
Many bikes would have better geometry (for me) and a nicer look with a shorter fork.
For example, the Santa Cruz stigmata.

[gribs]

I think the fork will make more of a difference on where your gravel riding lies in the gap between road and mountain biking. I went for the longer one to give a slacker head angle and more clearance as my intended use is effectively old school mountain biking with road sections to get further from home.

I've finally finished the build (I still need to see how many spacers to use below the stem and do the final cut of the steerer):

SPcycle G026 green chameleon with the following components:
- Schwalbe G-One R and RX Pro (rear/front) 50 mm on 25 mm wheels. There is about 5-6 mm clearance on the chainstays (5 mm hex wrench clears it, 6 mm hex wrench rubs a bit).
- GRX 2x11 groupset, with RX812 rear derailleur + XT M8000 SGS cage mod to have a massive gear range: 48-31 and 11-46.

I've only ridden it in asphalt so far, but very pleased with it!

Hi !

I am planning on building a road adventure / light gravel bike with 2x11 transmission.
Do you guys know if it possible to fit a Zrace unchained 50-34 crankset with the frame ?

The chainline is given to 47mm on the website of Mondice but I don't know how to tune it.

Cheers !

The chainline of the 2x of the ZRace Unchained is 44.5 mm. GRX 2x is 47 mm. With a road FD you'll limit the tire clearance, I guess you could fit in a 45 max. And not sure if the chainring will hit the chainstay with 50-34 and being 2.5 mm inboard, I'll try to take a look at my GRX 48-31 and will try to guess if the road crankset will clear it.

PS: I've checked, and I think a road 50/34 wouldn't hit the chainstay (can't say 100% for sure, but based on the clearance I have, I think it'll fit). You'll only have the problem of reduced tire clearance with the road front derailleur.

My bike came yesterday and I finished around 90% of the build.
Along with the frame I ordered a pair of 9velo gravel wheels which showed up today.
Front wheel is ready, but I am waiting on another 50mm RX-PRO for the rear - which is fine, since the weather is pretty bad and I cannot ride anyway.

Build went smooth, even the rear break cable got through on the first attempt without any issues. I added some cable padding to prevent any cluttering, but that's it.
I made a mistake on the front break adapter and mounted it for the wrong diameter - not realizing that you could run 180mm. Lucky as I am, I had enough cable to pull it down and mount it for 160mm :-)

The stock seat post was way too short to reach my saddle height, but I simply re-used the seat post from my old bike.
I opted against integrated handlebars until I can figure out my reach and stack dimensions, but for me it looks nice enough as it is.

Components I used:

Frame
Frame: Mondince FM326
Size: M
Fork: 420mm

Drivetrain & brakes
shift/brake levers: SRAM Rival AXS D1
brake system: SRAM Rival AXS D1 (160/160)
rear derailleur: SRAM GX AXS, 12 speed
bottom bracket: SRAM DUB Road Wide
crankset: SRAM Rival E1 Wide, Powermeter Spindle, Dub, 42T - 165mm
cassette: SRAM XG-1275, 10-52T
chain: Sram X01
pedals: Shimano XT M8120

Cockpit
headset: PRO Headset Integrated Cable Routing (I prefered this one to the stock option for the cable routing below the stem)
stem: DEDA Mud Peak - 80 mm +/-6º
bar: Newmen Advanced Gravel Bar 318 - 420mm ("liberated" from my spouse since she is running 360mm)
handlebar tape: SRAM Red handlebar tape (wasn't the plan, my preferred PRO Race Silicon ripped while unwrapping it)
Spacer: ZTTO blue alloy spacer (from Aliexpress)

Wheels
wheelset: 9Velo 2026 Gravel Disc GB series 24H/24H - 28mm inner width
valves: 9velo stock, but with schwalbe click valves (SCV)
tyres: Schwalbe G-One RX Pro, TLR, 50-622

Seating
saddle: PRO Stealth Performance
seat post: PRO LT 400mm 27,2mm/ 0mm offset

--
In case you need to order SRAM brake parts:
For the rear you need 32mm flatmount screws (SRAM part: 00.5318.005.002) and the standard flatmount adapter for 160mm (it should be part 00.5318.018.001 - but I had that already here)

Front: use the Flat Mount 0F/20F | 140/160 mm (part number: 00.5318.018.000) for the front - it includes all bolts.
For 160mm discs, you need to build it with the 140mm side because that give you the effective range for 160mm. That's because the fork can take up to 180mm rotors.
If you want to actually run 180mm rotors, you need to switch the adapter to 160mm.

Tire clearance doesn't work that way. With a GRX FD I could easily fit 65mil tires if my frame allowed it

[gribs]

I'm using a 12 spd 105 derailleur on mine as I had one spare and it doesn't effect tyre clearance at all.

I'm also interested in this frame.
What I'm curious about is, are you guys sizing down? Normally I'm a classic large with 185 cm and 87 inseam.
And, is this frame done by tantan or not? As tantan still has the rack mounts and only the short fork on site.
Same for the price, simillar to tantan/serpah/sp?

Thanks

I would use Bike Insights to compare the geo to other bikes you like the fit of.

Here's the one for the shorter fork: https://bikeinsights.com/bikes/689cb67b11f2e8001a0c85b2-mondince-fm316
And the longer, 420mm fork: https://bikeinsights.com/bikes/6917726c3de161001abe646a-mondince-fm326

thats what I did already, but still some questionmarks as this frame would be longer than my road bike.
But cutting the stem from 110 to 80 should work.
