Not carbon and significantly heavier, the Stone alloy crankset has an option for a DUB Wide spindle.  Ballpark price is around 120.00USD and they come in at +500g. 

Really, really pleased with mine.  They have some of the best machining and fit that I have encountered with chinese bike brands.  Eventually, I will upgrade to SRAM Red cranks just to shave off 200g of weight.  Highly recommend the Stone cranks though.

I tried really hard to get one shipped to the UK but the shipping costs out weighed the purchase.  I ended up getting a 2019 Tern surge frame off Ebay from Japan.  Loads of fun to build and ride.  Would have loved the opportunity to try a Java with hydro discs and electric drivetrain.

Minis are a cool niche bike.

After learning in this thread that Pirelli 40c TLRs were not designed for 32IW wheels.  I continued to ride them for about 500mi.  No issues to report.  My OCD kicked in and I did order Goodyear XPLR 40c road tires.  Expensive, yes.  Took forever to get, yes.  Mounted them on my Tagoola’s tonight.  Interestingly, 40c Pirellis mounted on 32IW rims measured at just over 43mm with 38psi.
Goodyears measured at exactly 40mm at the same PSI.  Interested to see how they perform tomorrow.

Time and some recent physical/medical limitations are preventing me from riding this bike as I originally intended.  This is a complete build, finished FEB 2025.  The whole bike has had very minimal mileage on it and cassette/tires changed outt on in NOV 2025. Garage kept and cleaned after every ride. I have no issues with this bike and I love the way it rides.  Full build details below. Asking 1800GBP. 

DM me your questions or for more detailed pics.  Looking to sell within the UK but will consider the EU. If you are in Wales or England, I would consider meeting up within 1-1.5hrs of my location.  A lot of time went into this build.

- Frame: XMCS CS-R01 size 515 (Medium). Black raw finish with glossy clearcoat.

- Wheelset: Go-Zone 50mm deep, 24mm internal, 30mm external. Matte black finish.

- Tires/tubes: Pirelli 30mm front, 32mm rear. Latex tubes. Rims have been tubeless taped.

- Cockpit: Ascent Aeroo 36cm with Riro stem. Hydraulic cables are Zeno V2. I built this to be able to remove the fork for packing in a Post Carry case. Remove the bar, take the stem off, disconnect the cables and its ready to pack. 

- Crankset/BB: Elilee X310 24mm 165mm. Stone 50/34 chainrings.  Flawless.  Origin8 T47 BB.

- Groupset: 105 Di2. Only run on waxed chains. Cassette Goldix 11-34.  Will include and Ultegra 11-30 cassette.

- Saddle: Ryet carbon sadde (not sure which model).

- Computer mount/bottle cages: From random Aliexpress vendors.  Will include with purchase.

Just tried 40c Pirellis on 32 IW Tagoola XPLRs for the first time.  Coming from 30F/32R Pirellis on 24IW wheels on my standard road bike.  FWIW, I probably could have gone with 35s, because 40s blew up to 44 WAM.  Definitely a tight fitting tire on the Tagoola wheelset.

Only one ride so far. So, I need a few weeks on them before I can give a good personal assessment.

At the OP.  You mention getting into gravel and weekend riding, along with geo that doesn’t cause lower back pain.

I just built up an FM286.  Very relaxed geo and supposedly 50c clearance. I’m not planning on going bigger than 45c for the moment.  I’m in the process of putting miles on it before I post my thoughts. 

The build has begun. Started by pulling the brake cable. But the hole inside the frame is not big enough for the brake hose.
Tried with a magnet, but there is a rim all around.
I can thread a steel wire 3mm thick. But not 5mm.  Any tips?
After 10 cm its stop..

I had the same issue when building my XMCS CS-01.  I used needle files or jeweler’s file to probe for the obstruction.  Once I located it, I was able to clear a path by very lightly running a drill through the exit hole.  When I say, “drill”  I mean use surgical precision, slow, steady and probably no more than a 1 full rotation of the drill bit and the path was cleared.

Bottom line, there is a piece of carbon blocking or catching on the brake hose as it moves through. 

You still need to detach the hoses for travel? Not enough slack to just strap the bars to the fork?

Yes, my set up is specifically for use the old Post Carry case.  I’ll try to provide pics later this week.  I’ve experimented with a number of different stems and V1 and V2 Zeno clips. It’s both expensive and time consuming to fill a very niche purpose.

Basically, I remove the stem face plate, remove the stem, disconnect hoses.  From there I pull the fork, bag the headset bearings and spacers and it’s ready to pack.
