I have a 2004 z150 and was thinking of changing the lower clamp and axle setup. I am not sure of my options but know that you (TNC) either own or did own a 2004 z150 sl. Can I switch to the bolt on axle from my qr20 axle? I hate twisting QRs on my z150 and don't mind carrying a hex. Is the QR axle any easier/faster to install than the bolt on? Any loss of weight up front would be nice so is one lighter than the other? I would assume the bolt on would be lighter due to lack of a QR system added to the axle (not trying to be a weight weenie... just curious...). I was also curious as to my options for the QR20 Pro clamps. I have seen some bolt on QR20 clamps that look different than the ones that I have. My lowers have both QR20 clamps and a QR20 axle. I was hoping to stay with Marzocchi parts and not pay $70 for the North Shore Billet clamps. The Marzocchi product is similar to these clamps and is not QR. You have to bolt the single clamp. Sorry for the long message, but I was hoping for some insight.

It doesn't matter. QR is somewhat faster if you take your wheel of all the time. qr is not that heavy, just more convinient. I think you just need to buy the quick release itself and you'll be set.

Just get a new Z1 lower and ditch the QR20 all together.

yes, either axle will work

Yeah, I have a couple of modified air/coil '04 Z150SL forks with what's referred to a QR20 Plus. It's a toolless setup that works very well IMHO. I think part of the problem many have had with this setup is an improper installation order which can cause overtorquing of the flap retaining bolts or allowing the flaps to come loose and fall down.

In reality the QR20 in any of its forms is totally reliable, and it's a shame that bad installation methods have probably caused its demise. Anyway, I looked in my '04 manual, and apparently all the 20mm forks except the Monster, 888, and Shiver used the QR thru axle with a QR handle. The only difference was the flap retaining method...one with breakover flap and the other with an actual bolt to retain the flap.

If you obtained a thru axle for a Marz QR20 fork system that has a bolt-on end rather than a QR lever end, then I don't know why it wouldn't work. On the other hand, I don't know why you'd want to change from the QR lever end thru axle, as it's definitely been proven reliable. The flap and flap retaining system is where the controvery has been. Regardless Marz does make the bolt-on flap system to replace the tensioned flap system like yours. It's a simple setup and should work fine. I'd check with Marz and request the NON QR20 Plus bolt-on flap retaining system that uses a 6mm allen to install and remove the bolt holding the axle flap on each side.

I also just noticed that Marz does mention in their text that there is a threaded axle style like you have pictured, so you should be able to get everything from Marz. The simple bolt-on flap system I see pictured in the '04 manual looks like 4 total pieces...two pieces for each side.

Can you tell us why you want to change? Do you have broken QR20 Plus hardware? Are your flaps coming open when you ride? Have you had problems with the QR20 axle? Just curious. When our group goes on bike trips to Moab and such, I really like my QR20 Plus setup. I turn the bike upside down, pull the wheel off in seconds without tools, and throw the bike on a Hurricane Fork Up, and I'm through. BTW if you get a Fork Up for a QR20 Marz fork, don't worry about spending the extra money on the one recommended for QR20 forks...it's the same 20mm Fork Up as the standard model, but it comes with a QR20 axle...just use the one that's on your QR20 fork.

You can get new lowers with bushings and seals much lower than that if you look.

I swapped out my QR clamp to the screw type on my 04 Z150 - just paranoid about those flaps coming open at a bad time. I believe the screw on type are used on the Super-T, or maybe it's just an option on that fork. Got the parts through my LBS.

Anyway, I've been using it that way for a couple years and have no complaints.

I cannot find these bolt clamps anywhere online. How much did you pay for these if you don't mind me asking? The QR20 clamps are about 25 each! :eek:

Answer to TNC's questions...

I do not have any real problems with the QR20 Pro/Plus system. By the way, what is the difference between Pro and Plus? I was just trying to see if I could still get a bolt on axle and clamps for the z150 and if they were compatible. I am looking into getting a new 20 mm fork for one of my bikes but have never had a true 20mm dedicated front axle. I thought by buying the hardware to make the z150 a completely bolt on system I could see whether or not I want to go that route. I have a Pike and love the maxle setup, but I would also like a 2006 Z1 Freeride Light w/ ETA and TAS. I thought this would be the cheapest way to see if I really like dedicated 20mm front ends (not that there is much of a choice anymore if you really want a good quality and stiff trail/freeride fork... I could be wrong... Just my opinion...)

I have the lower through axle bolted onto my 2004 Z150 Drop Off. It requires a 6mm Hex Wrench to remove. They work if thats what you're asking. They all fit the same (My friend has the quick release axle, I have the bolt on).

Here is a picture:

Like most Marz small parts - not cheap! I think these were about $20/leg. You get a bolt and a nut, the nut is shown in the pic below. The pic is from www.bti-usa.com, but they don't seem to stock the bolt. Not sure where my LBS ordered it from. Maybe QBP? Or maybe BTI had it, but doesn't any longer.
