Bikes of Bentang Jawa

Eight decisions, ridden 1,500 km across Java — this is how 100 bikes answered them

100 bikes documented · 2026 edition

6 of the 8 components are documented for at least half the field, the other 2 for fewer than half.

Pick a component to see how the field splits.

Rubber

Tyre width is on record for 83 of the 100 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.

The Frames

Frame type is on record for 96 of the 100 bikes in the 2026 field; what the frame is made of, for 43.

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 100 of the 100 bikes in the 2026 field, across 44 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.

Where a frame was built is not something the record captures, so this section counts makes and stops there. The Indonesian-maker story the data can prove is stitched, not welded — it is in the bags.

Drivetrain

Chainring layout is on record for 82 of the 100 bikes in the 2026 field; the groupset itself, for 95.

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.

Groupsets

95 of 100 name a groupset, and almost every one differs — 82 distinct entries. Shimano GRX repeats most, on 6.

Written more than once, all of them: Shimano 105 ×2, Shimano GRX ×6, Shimano GRX 810 ×2, Shimano GRX 820 ×2, Shimano Ultegra ×3, Shimano Ultegra R8000 ×2, SRAM Rival XPLR ×3.

Riders write this in their own words, so "Shimano GRX 810 11 speed" and "GRX 600" are two entries for parts of one family. Every bike's own answer is on its detail page.

Shifting

Recorded for 23 of 100 bikes — under half the field. Read what follows as a hint, not a verdict.

Wheels

85 of 100 name a wheelset, and almost every one differs — 73 distinct entries. Zipp 303s repeats most, on 6.

Written more than once, all of them: DT Swiss 1600 spline ×2, DT Swiss R470 ×2, Entity ×2, Fulcrum ×2, Vision Team 35 ×2, Zipp 303 Firecrest ×3, Zipp 303s ×6.

Depth, rim material and model year all get written into this one line, so two riders on the same wheel rarely describe it the same way. Every bike's own answer is on its detail page.

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 88 of the 100 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.

Seeing & knowing

Lights are on record for 79 of the 100 bikes in the 2026 field; a head unit, for 81.

156 hours means five nights. Riders carry redundancy: two front lights, two rear, spare batteries — and a head unit whose battery life decides how often they stop.

Cockpit & contact points — what we know least

In the 2026 field, aero bars are on record for 36 of 100 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.

Aero bars

Recorded for 36 of 100 bikes — under half the field. Read what follows as a hint, not a verdict.

Of the 36 bikes where it is recorded, 34 carry aero or rest bars. That is a strong number over a thin sample, and it may well be a self-selecting one — a rider who fitted aero bars has more reason to mention them. The data cannot settle that either way.

Saddles

Recorded for 30 of 100 bikes — under half the field. Read what follows as a hint, not a verdict.

28 different saddles are named, almost all of them once. Bring the one you have already broken in — day three is the wrong time to find out a new one hurts.

Pedals

Recorded for 18 of 100 bikes — under half the field. Read what follows as a hint, not a verdict.

18 different pedals across the bikes that name one — road cleats, and mountain bike cleats you can actually walk in. Too thin to say which way the field went, and there is barely a repeat in it.
