marzocchi am1 vs am sl on the 5spot

735 Views 14 Replies 6 Participants Last post by  AndyN
howdy kids.

so i just got an 05 5spot and i'm psyched to build it up. i was thinking about going for either the marzocchi am1 or am sl, and i was wondering if anyone had any input on the matter - i've written turner and i'm waiting to hear back. i'm building this up to be a lightweight agressive trail bike.

turner recommends a 130mm fork for the 5spot - the am1 comes in a 110-130 and a 130-150 - which one do i go for? which one is meant for the spot...?

throw me a bone, please!

130-150 is the one. It allows you to throw 20mm Z1 lowers on if you crave more siffness. SL will dive more than the 1 at the same sag setup. Have you considered 454 Pike air UTurn?

IMO the AM-SL sucks for light weight riders. When the fork was set up to be plush on the stutter bumps it had serious brake dive and bottomed too easily, the PAR should have helped this but it really didn't. The PAR ended up making the fork way too progressive when I used it to control bottoming.

In the end I just set the AM-SL up to handle medium and big hits and just dealt with harshness on the little stuff.

After a while I got fed up and switched to an AM-1, I couldn't be happier.
thats good to know - did you go w/ the 110-130 or the 130-150?

It was the 110-130.

Adjusting travel requires a shock pump and is not an exact science, no clicks on a knob at least. Basically you are just preloading the air spring to the point where travel is reduced.

do you think i can pull off the 130-150? they don't make the 110-130 anymore, unless you purchase the am1, and i'm not quite sure how that differs from the all mountain 1, w/ the exception of the coil/air hybrid. turner recommends up to a 130 mm fork i believe.

The All Mountain 1 in 130mm travel setting has the same A-2-C as the 2003-2004-2005 Z1 (518mm). So, if you like a slighlty more relaxed head-angle then the AM1 130-150 will be fine for the Spot. Look at the number of Spots in the database thread with the Z1 mounted. jncarpenter, MK and Bikezilla all have/had a 130mm Zoke mounted Z1 or ZAM1. Maybe they will post.

The 2006 AM! is not the same as the All Mountain 1 from 2005 or 2006. Rememer too that the 2006 All Mountain series is 2-3mm taller than 2005.

My AM1 is 130mm-150mm, I just leave it at 130mm all the time.

ok, i need you to translate a little bit. what is a-2-c...? and what would a relaxed head angle do for me...? the main reason i've been looking at the all mountain 1 is that it seems to combine the benefits of coils and air shocks, weighs under 5lbs, and if you believe the hype, does everything i'd like a fork to do - it's stiff, handles the dh's well, the climbs well, and still has tight steering.

but yeah, i've noticed the majority of people w/ 5spots either run the z1 or the vanilla rlc.

also - when you say the 2006 am1 - do you mean the am1, or the all mountain 1...? you think they'd come up w/ easier names for clarification.

thanks,

a-2-c = Axle to crown. Used to determine the height a given fork will raise the front of your frame. 5 Spot is designed around a 508mm (I think) a-2-c. Adding the 10mm of the Marzocchi will relax the head angle slightly to around 68.5 degrees. Slacking the Head Angle will make it more stable at speed in a DH situation but make it less precise for climbing (that's where the ETA on the All Mountain 1 comes in). IMO the fork is ideal for the Spot.

for 2006

AM1 = trash
All Mountain 1 = good

For 2005

There was only 1 version and it was referred to as the AM1and All mountain 1.

If I were you, I would reconsider the All Mt 1. It is a decent enough fork, however...for the 5 Spot I think a 20mm axle is in order. Also, I agree with Andy that the brake dive is an issue. Personally I would recommend the 2006 Marzocchi Z1 SL.
It is adjustable 130-150mm travel & has a compression adjustment that will allow you to tune low speed compression, effectively dealing with brake dive. Also, the new dopio air carts seem very nice & it is fairly light to boot. That would be my recommendation if you're looking for an air fork.

i actually just got off the phone w/ a turner rep - and he was saying that i probably wouldn't want to run the bike over 130 - he explained that he had a talas, and that if anything, he'll occasionally lower it to 120-125 for the uphills - but generally it was best to stay in the 130 range - so he advised getting a fork where the max would be 130. they do make the 05 all mountain 1 in the 110-130 - unfortunately, i can only find it in the icky mustard color in that range. yeah, color isn't everything - but i don't suppose anyone's come across the 110-130 in black...?

if not, i may go w/ the sl - which only comes in 130. but i guess ideally, it would be good to have something that if anything can go a little lower than 130. but i mean, how often do people go adjusting the fork anyways. but then again, wouldn't that be the point of buy an adjustable fork? sorry, just thinking out loud.

same thing w/ the z1s - they all start at 130.

130-150?

I have been through this same decision and I choose the 2005 AM1 which is butt ugly, but it goes from 110-130. My thought was that since I would be racing a bit and climbing a signicant amount that I would want to option to go less than 130mm. Marzocchis have a higher a-2-c than say a Fox in the same amount of travel. I would have much preferred the color of the 2006 since it is black, but with adjustability from 130-150 I would never hav the chance to lower it below 130. Most guys I know running the AM1 on thier spots run at about 120-125mm. Going with an 06 does not give you that option. I assume that if you are building a "lighter" bike then you will probably use it to climb. Tall a-2-c tends to make climbing suck IMO. Depending on the type of riding that you do will depend on wether you choose the 110-130 or the 130-150. If I could afford a new front wheel I would have choose the Pike 454 U-Turn if that helps.
...I have the 2006 Z1 Light ETA on my Spot & have recently been running it in 150mm travel. I personally prefer a bit slacker HT feel & HATE one that is too steep & twitchy feeling. We have some of the steepest, rooty-rocky climbs I have ever ridden around here & I haven't had one single problem climbing in 150mm mode. A 130mm Zocchi Z1 on the Spot feels perfect to me, I wouldn't want the HT angle any steeper!
It really depends on YOUR personal preference & terrain, but IMHO...if you're looking for a quick, snappy feeling bike...perhaps the Flux is a better choice.
I'd better clarify...

I mistakenly referred to my All Mountain 1 as an AM1.

I used AM1 as an abbreviation not realizing it was an entirely different animal.

I ride a 2006 All Mountain 1 and love it.
