Strengths:    Stiff, smooth, light, unique

Weaknesses:    Some extra maintenance (over regular forks) required, bob when climbing (but quickly eliminated with the PBR lockout)

Bottom Line:   
120 Ultra converted to140, then reduced to 110mm for a 29er.

I wasn't sure just what difference I'd notice with this fork; I'm not an elite rider or a "princess and the pea" type who notices a lot of subtle differences, but the Lefty does make a difference. The claims of stiffer and smoother, however, are absolutely accurate. One of my training rides very obviously proved just how smooth this fork is. I ride up a dirt road to get miles and elevation (~12 miles, 3000' steady climbing) and then back down. The road is full of washboard and with my Fox, my hands and arms would be buzzing and aching at the bottom. With the Lefty, I feel a very slight vibration blasting downhill over the washboard sections and nothing more. On singletrack, it goes where you point it and rolls smoothly over everything, even bigger hits and drops. And I have noticed some of the more subtle differences, too where I realize the front is gliding along smoothly where my old Fox would have transmitted some of that to me. And I can visually see it on video, too. I mount my Contour Roam on my frame against the headtube on the right side (clear field of view because of no right leg on the fork!) and the video is very smooth over some rough terrain.

Oh, and you save a bit of weight over a conventional fork, too.

This fork is great and I will eventually put one on my HT, too.

I purchased it from Project 321 and can't rave enough about their customer service. Jake worked with me over many months to help me figure out a direction (Lefty and/or wheels) and then get the order completed and installed. If you need/want a Lefty conversion kit for your non-Cannondale frame, call Jake!

Ultra Lefty vs. Speed Lefty Hub Spec

I read somewhere that the new Ultra Lefties use a hub with wider flanges. Does that mean a front wheel I got for my 2012 Flash29 wouldn't just bolt on to a Trigger 29?Read More »

'11 Scalpel 3 Lefty vs. Fatty Ultra questions

Hello, I am new to the forum. I recently purchased a used 2011 Cannondale Scalpel 3 bare frame. The bike was originally equipped with a Lefty that had 100mm of travel. I would like to know if there would be any problem with putting a Headshok Fatty Ultra with 80mm of travel on this frame? My con ... Read More »

Ultra Thin Headset Dust Cap Needed For Lefty

I’m looking for an ultra thin top headset dust cap. –Possibly homemade. I'm trying to fit a 2013 Lefty Carbon to my 2013 S-Works Stumpjumper Small and I'm having a problem with the stack height. If your short and you have a 29er than you need your stem as low as possible for CX, so I’m trying ... Read More »

Lefty Ultra 120mm w/ PBR (2010)

I'm considering buying this fork, simply because it has the sleek OPI look, but is cheaper than any other OPI fork due to the relatively old DLR platform. My concern is that this is a really rare beast. It is too rare? Should I avoid it? Prior year DLR2s were 110mm. This seems like such a wei ... Read More »

Making a Lefty Ultra PBR work on a Flash

I can get a good deal on a Lefty Ultra PBR. I have a few questions in relation to using this on my Flash frame as an alternative to a Lefty Speed PBR. Does this fork have the same A-C measurement as a Lefty Speed PBR? Are there any difference in suspension feel, damping and lockout between the ... Read More »
