I've been searching quite a bit for info on these forks, and still looking for info regarding weight limit. So let me try to add what little I can for those that are considering these forks.
I bought the Trigon MC10 29er model off of ebay from the seller cyclistbike, out of Taiwan. I sprung the extra $10~ for upgraded express shipping in the hopes that I'd get it quicker (I'm APO in Korea, so it's gotta get handed off to military transport then make it's way back over the ocean a second time). I think it made it here in record time as it arrived seven days later. Btw, he got 'em to the shipper the same day.
I was a bit concerned when I picked them up at the mail room due to the box showing some "wear," edges somewhat crushed/abused, but after pulling them from the box and a close inspection I couldn't see any obvious damage. So I plan to email the seller and recommend he use a sturdier box to ship them in as the one he used was pretty flimsy. Especially so for international shipping.
I mounted these up to an '08 Rockhopper 29er that I'm trying to breathe new life into. They're replacing a White Bros. carbon fork, nothing wrong with them per se, I just preferred the smoother lines of the Trigon's and what I've read on 'em so far. While I was at it I swapped out the Cane Creek S-3 headset with a Chris King unit. Something I was also concerned from the get-go about the A2C being shorter because all of the mtb/trigon photos I came across online seem to show the Trigons being significantly short, or at least they appear so. Because of that I ordered a 5mm crown race with the Chris King headset just in case.
Once I had all necessary parts on-hand I took everything to an LBS here in Korea that I've come to really like. Now, usually I do all of my own work but I don't quite have all the 'right' tools for the job on this one. And...I'm normally skeptical of the work quality by most shops (too many bad experiences, that's why I've come to do it myself, mostly), but it's a good sign when a little mom/pop/son shop in a little town in Korea has an immaculate-but-well-used work shop area fully-stocked with the complete line of Park tools, plus some.
About 45-minutes later the Trigon/Chris King combo was on. Ended up not needing the 5mm crown race, too tall. The standard version that came with the headset worked out perfectly. A word of caution though, as has been mentioned, the crown's outer diameter is larger than that of the headset's lower cup, so you have about a 1/4" of the crown that extends out past the lower cup. Not a big deal to me. I don't even notice it unless I'm right on top of it, looking at it.
Couple other points to mention that might offer some clarity for that others may find useful. The ebay seller makes no mention of whether or not these forks come with an expander plug, so I ordered one after the fact in the off chance it showed up without. Well, the Trigons do come with an expander plug, and a pretty bad-@zz one at that. Also, the photos listed by the ebay seller seems to portray the steerer tube as aluminum. It's not, it's carbon so you'll need a carbon-specific hacksaw blade if you're DIY'ing it.
No ride quality to report on yet, haven't had a chance to really wring-it-out yet, so more to follow on that later if there's any interest.
Hope this helps some for those on the fence.
