    Krampus suspension fork

    I think this might be the answer for a suspension fork for a Krampus Lauf Forks - The Lauf Trail Racer 29 - The lightest suspension fork on the market. The only problem with the current model is has max 2.35" tire. Perhaps Surly could work with Lauf to develop a 29+ version. I think I'd be interested.

    I disagree. The big tires already give you some undamped suspension. If you're gonna put suspension on the Krampus, get a real fork with some travel. The Lauf design makes more sense for a carbon framed light weight racer than a big burly steel Surly.

    I'm confused. Why do you think this is a good suspension fork for the Krampus? I was expecting to see something with big clearance.

    That is why I said "develop a 29+ version" It is the concept that may work.

    Perhaps your right.
    I was thinking that I don't need to much more suspension than what the tire offers. I guess that the tire provide about 15 - 20 mm of suspension when it reaches it's maximum "bottoms out" the fort would them come into play offering an additional 80 mm of travel.
    I am no expert it was just a thought.

    This fork requires NO maintenance! That's why it's better!

    Plenty of room for a 29+ tyre with a bit of DIY spacer manufacturing.

    Early reviews are not flattering. Gear Review: Lauf Trail Racer 29 fork | Mountain Bike Review

    Doesn't seem like a good match for the Krampus.

    I am considering buying a complete Krampus, and a Rock Shox Bluto fork. The Krampus geometry is corrected for a 120mm fork, so a hub, wheel build, and lower headset should be all I need. Am I missing anything?

    Rock Shox is saying that there is not enough room for the 29+ tire in the Bluto fork.

    All of the things you are taking into consideration are wonderful, BUT you can't do anything about the clearance under the bridge.

    I guess there is now a 29+ suspension fork the Manitou Magnum 34. It is on the new 29+ Trek. I trust this will work on the Krampus any thoughts?

    Aside from having to rebuild your front wheel with a 110mm 15mm thru-axle hub, I see no reason it wouldn't work.

    For people like me who want the squish for day rides but rigid for multi-day trips this would mean two wheels. Anyone know of a simple endcap style conversion kit for hubs to switch between the two sizes?

    wouldnt you just need 2 15mm x5mm bushings to make your 100mmx15mm a 110x15mm

    Why the HS? I thought they were both tapered, or are they different dimensions despite both being tapered?

    The Krampus fork steerer isn't tapered, it is a straight 1 1/8. see Forks | Parts and Accessories | Surly Bikes

    The hub now is 9mm with a skewer on the Krampus fork, can you convert that to a through axle?

    Just did a google. I see some hubs can be converted. I have an XT on mine, I understand it can't be converted.

    The same headset can be used for both fork. It's just a different crown race.

    Looks like length wise (axle to crown) the 100mm would raise the front end about 15-20mm, the 80mm would be a better fit geo wise but might not be enough travel considering the Krampus' attitude. Though the wide tires throw in some variables in regards to suspension I'm unqualified to comment on.

    The 100mm Bluto on the other hand would put you very close to the stock fork and offer more travel.

    Surly states that the stock fork is 120mm suspension corrected. Where did you get the Magnum axle to crown dimension? I can't seem to find it.

    https://www.benscycle.com/p-19921-ma...00mm-mblk.aspx

    Not sure how correct that is, but it was linked from the "buy now" button on Manitou's site.

    Surly states that the Krampus fork is fork is corrected for 100-120mm suspension travel, which makes no sense. The axle to crown on the Krampus fork is in the range of most 100mm standard 29er forks. A 120mm fork would raise the front 15-20mm, which I'm sure Surly thinks will be fine given their statement, but the tires won't fit. For a fork with 120mm of travel and clearance for the 3" tires it looks like the Bluto, again, (at 531 axle to crown) is your best option. But it's going to raise the front end ~10mm compared to a standard 120mm fork (or the Krampus fork + 20mm), depending on sag.

    Seems like it may become an extensive/expensive experiment. Though I think the Bluto can be adjusted down if it proves too long at 120mm. I'm not sure of the adjustibility of the Magnum.

    The issue with the Bluto is that if you have proper crash, the adjuster knobs foul the Krampus' downtube.

    That was a quick response:

    "The new Manitou Magnum 100mm travel fork with work just fine on our Krampus. One of our Enginerds rode one out in Sedona about a month ago and said it works well on our Krampus frame. Plenty of tire clearance.

    The 120mm travel Magnum is going to be just a little too long and add more stress to the frame than weíre comfortable with. So, if someone decides to use the 120mm Magnum on their Krampus that this could potentially void a warranty down the road if itís directly related to a failure.

    One thing worth mentioning is that this is a boost fork (110 spacing) and the stock wheel that comes on the Krampus completes is not compatible or convertible."

    I was unaware of this issue. In this case the Bluto would not be an option for use on the Krampus.

    That's too bad because you could have gotten a 120mm fork at the same length as a 100mm Magnum.

    Edit: Actually with something like he FSA Head Block headset you could still get away with it. It's kinda hard to find in the US, and you will only need the top cup, but it's an option to squeeze some more travel in there.

    I was so excited for the Magnum until I found out about the boost shenanigans. Not to mention the price tag of the magnum and the current price of a boost hub...

    Apparently, if you're running Hope Hubs on your regular Krampus frames, they will be doing axle and disk mount adaptors so you can convert to Boost110.

    This makes me very happy!

    Where did you get this info? I'm curious about how they're making the brakes line up.

    Rockshox is releasing the Pike RC and Yari RC in 29+ soon. Both of the normal 29" forks come in 120mm travel so I assume the 29+ would be the same. Haven't found any info on the A-C measurement yet.
