Alright everyone, can I increase the travel of drop off IV 120mm to 150 but moving spacers around inside or do I need specific 150mm internals? Not got the forks yet so checking with you guys 1st

Shortening travel is a lot easier than extending it. Original Drop Off IV's from 2006 were 130mm if I recall correctly so probably a no go in lengthening the travel past this

I only ask as I've seen bikes fitted with 150mm version so was unsure if internals were same to save money or actually different ones

You might be in luck it really depends on the fork. If I recall correctly you could use a spacer to lower the travel or you would cut the air shaft and tap it.

Noob here, searching for help, please! Let me know if this is the wrong place to ask. I just purchased the Marin Rift Zone 27.5. I ordered it by mail so it came disassembled. I just finished putting it together, but I think a piece is missing?

This is what the front axle looks like on one end. Shouldn't there be a piece to hold the axle in place? Or am I wrong? I've searched the box and wrapping a dozen times with no luck. Does anyone know what typically comes on the Rift Zone? Is that a piece I can order on its own, or how much do I need to replace? Also, what is that piece even called? I can call the shop I bought the bike from and ask if they can help, but not sure how to describe what I'm missing.

Here are some other images if it's helpful. This is the other side of that front wheel axle:

And this is the back wheel, which I assume the front wheel should match?

Thanks in advance for any help.

And while you flip the handlebar back: do it such that you fix the routing of the front brake hose...

It looks like on of those string puzzles like this. Flip the bar under the down tube and then the others are routed wrongVery confused * .. Easiest is just to take lever from the bars and re-attach after untangling.



Just in case you flipped the bars like this because you want to have the front brake on the right, that doesn't work with those kind of brake levers: reservoirs should be on top. The hoses can be swapped, but as brakes are rather important let a professional do it or assist you.


*Aw solved the puzzle: release handlebar clamp bolts of stem, hold handlebars and make a full 360 CCW with the fork to unspin the hose. Re-attach the handlebar.

For safety sake, take it to a shop before you ride it, to avoid killing yourself.
A few bucks to have them check it over is way less expensive than a new set of teeth!

Aaand this is why Marin (and most reputable bike brands) will not allow a dealer to sell a new bike still in the box. Whatever shop sold this one could get their dealership rescinded for doing this.

Yes, those handlebars are backwards.

Yes, OP should have a qualified mechanic check the bike over.

One other thing worth mentioning is that the rear "thru axle" is very different from the front one on the base model Rift Zones because it's a 5 mm QR lever with a weird adapter. The bike can be upgraded to a normal 148 x 12 thru axle if you buy a real thru axle wheel (this one is not) and the correct thru axle to go with it. There's a weird threaded adapter on the driveside that you will need to remove. The correct axle is 174 long x 12 diameter x 1.5 thread pitch x 20 thread length, and you can just use Salsa part number FS0011 (Marin refused to sell me a stock one so I had to find another brand).
