Most bikes in my budget come with low end suspension forks. Mostly they are Suntour.

Does anyone know the difference and what series of suntour forks are better?

I have seen the following:

XCM V2

XCM V3

XCT V2

XCR


They all seem low end but what makes one different than the other besides travel?

Thanks for the links but this doesn't explain much to a noob like myself. I have already been to their site. That is why I am asking hear because it doesn't explain to me the difference or what is better.

It seems like they rank from from best to worst:

XCR
XCM
XCT

I wonder what "momocoque" construction means.

Don't worry about it. I've heard that Suntour's forks are better than RST's forks, which is nice. But think of it as more of a placeholder. Sooner or later, you'll break it or it'll freeze, and then you can replace it with either a rigid or a "real" fork.

Just ride some bikes and buy your favorite. I bet you won't be able to feel the difference between different Suntour forks.

My '05 Fuji came with a higher-end Suntour and it was no good from the start--no rebound dampening, no adjustments except for air pressure. When you weight 230, like me, plush isn't an option.

If you are looking to upgrade, save your dough for something better. You will get what you pay for.

Here you go

Doug from SR Suntour here. The hierarchy from low to high would be XCT, XCM, XCR. V2, V3 has to do with the 'version'. higher number is newer generation.

Forks specified by different bicycle brands can be configured in a number of different ways, so its hard for me to understand exactly what you are looking at, that being said;

Our XCM and XCR models come with 30mm stanchions. ( the upper tubes) if you compare this to other forks in the price range, many of our competitors will often use 28mm stanchions. Larger diameter = improved stiffness and strength. Also, the pitch, or width of these two forks is 130mm. You will find that to be a bit wider than many of our competitors. Generally speaking, wider is better.

Second, our XCM and XCR models are what we call QSP, or quick service products. That means if your fork's internals ever wear out our suffer a problem, the fork can be fixed easily by replacing the entire cartridge.

Finally, if you are shopping for a bike that is less than $1,000 I'm sure you have seen that many of those bikes are equipped with SR Suntour forks. The primary reasons for this are based on the fact that the bicycle brands have come to trust SR Suntour to supply them with a reliable product that performs well. (that may seem simple, but its a big deal) Additionally, we operate service centers in North America, Asia and Europe to back up our product.

I hope this helps and good luck in purchasing a new bike. Ride it alot!

Doug

Wow - I'd have thought that someone from Suntour could have shed a little more light than that on what is a VERY confusing product lineup.

I have the Dart 3 29er 100mm fork (28mm stanchions) on my bike and my son has the Suntour XCR-LO 100mm on his 2009 Avalanche 2.0. Adjustable rebound and a blow-off valve on the lockout with the Dart 3 are pluses. On the other hand, the 30mm stanchions, better compression dampening and VERY slick progressive lockout lever on the XCR-LO make it a better fork in my opinion. I know, I know - everyone slams the Dart so saying "better than a Dart" seems like damning with faint praise. However, all Tora forks except the Tora 318's (Motion Control) have an unsophisticated TurnKey dampener, steel stanchions and non-serviceable bushings - just like a Dart fork. Most coil versions of the Tora lack adjustable preload which the Dart 3 has and several Tora models are missing a lockout feature which, again, the Dart 3 has. The major thing that separates all Tora forks from all Dart forks is 32mm-diameter stanchion tubes vs 28mm. Not that I think a Dart 3 is all that great, it's just that I think most Tora forks aren't that great either and that a Suntour XCR can be a pretty good fork - especially given it's low price.

Perhaps the best way to get a handle on the features available in various SR Suntour forks is via this link: SR Suntour Tuning Base

Bike manufacturers and Suntour themselves are often less than clear about what you're buying. My guess is that many consumers - after sampling the horrible Suntour M2025 pogo fork that comes on nearly every entry-level bike these days - write off the entire Suntour brand as junk but that's hardly the case. You can look through the exploded views of Suntour forks using the above site to get a better idea of what each model's properties are.

It doesn't help that Suntour makes many dozens of forks all with cryptic codes:

SF10 = Suntour Fork and the "10" is the model year
then comes the fork family (XCM, XCT, XCR, Epicon, NCX, etc)
then comes the fork's feature codes:
...P = Post-mount brakes
...D = Disc brake mounts
...D-P = Disc mount and Post-mount brakes
...E = ????
...DS = ????
...MLO = Mechanical Lock Out
...HLO = Hydraulic Lock Out
...RLO = Remote Lock Out
...LOD = yet another type of lock out unit?
sometimes there is a size (20, 24 or 26-inch wheel)
then usually comes a travel or travel range
sometimes there is an axle spec 15QLC or 20QLC (15mm or 20mm thru axle)

Not easy to figure out what you're spending your money on. Curiously, I haven't found that Suntour lists a range of springs for different rider weights. Unless you're of average weight, it would be nice to know before you buy any bike with a coil fork that a lighter/heavier spring is, or is not, available, no?

Perhaps Doug from Suntour can elaborate on what all those cryptic product codes mean and explain what the situation is with obtaining alternative-rate springs? What separates the NCX, Axom, Radion and Eipcon forks from other Suntour forks?

Suntour and Marzochhi are together I believe. Spinner made some of The RS stuff untill 2006ish. Now Spinner is on its own and that is why you pretty much dont see spinner in america anymore.
So who makes Rockshox now?

If older Rockshox is really Spinner, then maybe a Spinner fork wouldn't be such a bad thing.

For me, a good fork is something with relatively stiff stanchions, tunable spring rate and sag, and a rebound damper. I really like having a compression damper, but I don't think it's necessary to make the experience of riding with suspension better than the experience of riding rigid. I think the other stuff is. Finally, a fork should be sturdy enough to take anything wheels-on-the-ground riding throws at it, and the occasional largish jump onto a good transition or drop of a foot or two.

It's shockingly easy to rule out quite a lot of what's on the market just with those few conditions - a lot of the low end forks don't have spring kits available, which means that spring rate's not tunable. Rebound dampers are a bit trickier, since most forks sold now claim to have them - you really have to read reviews and see if they work. And they may work for lighter riders but not heavier ones.

If I was looking for a fork for a loaner or tight-budget bike, I might be open to something from Suntour, Spinner or even RST. But I'd need to know I could get the spring kit to make it work for my weight, and I'd need to be able to read reviews and not find a lot of people saying "I couldn't tell if the rebound damper did anything" or "I landed a small jump and shoved the compression rod right through the stanchion. Little metal things went everywhere!" Actually, plastic caps on the crown might kill the deal for me too.

I've ridden a few Cannondales with RST Deuce's and those forks felt pretty good. Air adjustable, 32mm stanchions, and aesthetically appealing. What is your budget for a bike? I might be able to help you out.

I ran across this post by a guy who found different springs for his Suntour fork:
http://www.bikeradar.com/forum/viewtopic.php?p=15991688

Hunting around some, I found that the XCM forks appear to have 30mm stanchions (28mm on older versions and with a clunky On/off lockout) and aluminum lowers while the XCR forks are 30mm with magnesium lowers. Other than that they seem pretty much the same.

Hi, Doug from SR Suntour here again. Here are some answers to your questions:

...E = ???? - versus D - Typically E is chromoly stanchions and steerer versus D which is STKM stanchions and steerer

...DS = ???? - Don't know at the moment.

LOD - this means Lock-out with Rebound Damping

In our 'system; R typically stands for Remote and D stands for Damping, but is really rebound damping.

NCX = 700c city bike fork
Axon = short travel XC Race fork
Radon = short to mid-travel general purpose fork
Epicon = mid-travel Trail to All-Mountain fork

Finally, I am hopeful that in the coming months/years you will see improved consumer based communications from our company so that it is easier to understand the features and performance of our products.

Thanks.................Doug

Hi Doug,

Are either of these forks Hydraulic?

SF11-XCR MLO 29'

SF11-XCM V3 MLO 26'

Having a spinner fork in the united states is a bad thing. For some reason, they only send there junk here. The spinner grind, eagle, other forks you find on low end entry level bikes are junk. The spinner aeris and cargo are decent forks. I use to have a cargo air that I got off ebay and it worked really well. It had 100-140mm adjustable travel, a thresh hold lock out that work like the flood gate on the newer RS stuff, and rebound. it was heavy at 5.4lbs but worked pretty well. The aeris is a sub 4lbs fork (One version I think is 2.9lbs.) With a decent damper. Problem is you cant find these forks very easy in the US and finding parts for them is almost impossible.
