Bikes of Bentang Jawa
Nine decisions, ridden 1,500 km across Java — this is how 109 bikes answered them
Pick a component to see how the field splits.
Rubber
Tyre width is on record for 88 of the 109 bikes in the 2026 field.
Java's 1,500 km is tarmac, broken tarmac, and the occasional excuse for a road. Tyre choice is where riders place their bet — and the field bets narrow.
Width
Most of the field runs 28–32 mm

Wheels
Something about the wheelset is on record for 83 of the 109 bikes in the 2026 field.
Under the rubber, two decisions: what the rim is made of, and how deep it is. One is paid for on every climb, the other in every crosswind — and both are still there at 3 a.m. when a pothole finds you.

The Frames
Frame type is on record for 102 of the 109 bikes in the 2026 field; what the frame is made of, for 44.
Road bike or gravel bike? Across Java the honest answer is "both, and it depends on the potholes" — but road bikes have the majority here.

The badge on the down tube
A make is on record for 109 of the 109 bikes in the 2026 field, across 48 different names.
Which badge is on the down tube is the one decision on a bike a rider can copy outright. What this section can say about it is decided entirely by the count above — how many of this edition's bikes named a make at all.

Drivetrain
Chainring layout is on record for 87 of the 109 bikes in the 2026 field; the groupset itself, for 100.
16,000 metres of climbing is the whole argument. Gearing here is not about top speed — it is about still being able to turn the pedals on day five.

Lowest gear, easiest first
The easiest gear in the field is 0.65 — a 30t ring on a 46t cog
Smallest chainring divided by biggest sprocket. Lower is easier. Bars scale to the hardest gear in this edition (1.13).

Mullet builds
13
bikes ran a mullet — road shifters driving an off-road derailleur and cassette (GRX, Deore, XT, XPLR). It is the cheapest way to buy a climbing gear a road groupset will not give you.

Carrying it all
At least one bag is on record for 91 of the 109 bikes in the 2026 field.
This is where Bentang Jawa stops looking like every other ultra. Tailfin and Apidura are here, of course — but so are Bandung and Jakarta workshops stitching frame bags to order, one rider at a time.

Cockpit & contact points — what we know least
In the 2026 field, aero bars are on record for 45 of 109 bikes, saddles for 30 and pedals for 18.
Six days on a bike means the three places you touch it matter more than the frame does. It is also the part of a bike a caption describes least completely: the frame and the tyres get named almost every time, the saddle and pedals far less often.
