My Pivot Mach 4 SL build

[rapsac]

Whilst waiting on the frame... a small geometry comparison made between the Mach 4 SL and some bikes in the same category (100/100 F/R travel).
What becomes apparent is that the Mach 4 SL has a huge standover clearance - resulting in a lot of seatpost showing and giving a lot of room for a dropper if so desired.
This compared to bikes with more or less the same reach and/or effective top tube measurements.

Pivot headset 71g


DT Swiss rear axle delivered with frame, handle non-removable 65g (not to be used)



Seatpost clamp delivered with frame 22g (not to be used)



Derailleur hanger incl bolt 20g

Ah, there she is. A bit shy of the scale... with good reason I guess

Since the damper rebuild parts were not in yet I have picked it up and will have the remote removal done later.

5 water bottle holder bolts as supplied with frame 15g (3g each)


These will be replaced with the Carbon-Ti ones shown earlier, saving 10g total.

[rapsac]

Some parts to finish:
Tyres Kenda Booster Pro 29x2,20 614g and 617g each




AXS shifter and clamp 71g and 11g




XX1 eagle DUB crank 175mm incl 34t ring:
206g+226g




Not pictured: Crankboots 12g for the pair and 1g for pedal spacers

Pressfit bottom bracket DUB for 92mm shell, incl 2mm spacer



XX1 cassette 10-50 369g



AXS XX1 derailleur incl battery 379g



Carbon-Ti rotor bolts 12p 13g
(The Extralite ones have 20T, these ones more regular 25T, better for unscheduled trailside issues)

[rapsac]

Fox 32SC 100mm factory 2020 model year with Silk decals



1421g uncut, no axle, no expander

[rapsac]

BikeYoke Divine SL 396g, excl cable/remote

[rapsac]

Carbon-Ti alu front axle QR15 boost Fox, 35g
(Not lighter than the Fox Kabolt, but matching the rear axle)



Carbon-Ti alu rear axle E-thru boost, 33g



Extralite axles are lighter, but have the hex key entry on the other side, so no regular torque key can be used. And prefer the match with the hubs for a clean build.

[rapsac]

Ouch... the ‘SL’ may not be deserved. Fortunately not unexpected.
Large frame, no water bottle screws, no derailleur hanger, no saddle post clamp, no rear axle, no remote cable, incl rear shock: 2420g

[rapsac]

Temporary hack until 3pos damper head arrives. Unfortunately needed because of the push (cable pull) to unlock of the Fox rear shock.

[rapsac]

Rear derailleur hanger check and alignment.

[rapsac]

Rear shock weight, excl cable 278g

[rapsac]

Tune Fuseplug barend protectors 12g

[rapsac]

Anti-noise sleeve for brake hose (not weighed)



BikeYoke clamp (the Hope matchmaker adapter for my old Race Evo levers place the trigger in an uncomfortable position): 13g

[rapsac]

So with a bit longer legs the visual appearance of a low top tube / high standover height does takes some getting used to. (read: not used to this look)



This is a large, my height is 186.5cm, inner leg length of 89.5cm for reference. According to dealer and Pivot size table it should be ok’ish.

Build almost done, brakes still to bleed/rear to fill up after installing a new hose, 9.95kg as pictured with temp tires and tubes (to seat tubeless tape).

PS: sorry for the uninspired picture... will do better next time.
