Grease_Monkey Posted May 17, 2017 Share So I am a big fan of carbon, and I know it is not as fragile as some believe, but... I am a 105kg guy, and I tend to steamroll more than take the best line - dual sus has made me lazy. I have however recently built a SS, and fitted a carbon fork to it (MRP Rock Solid) - first rigid, first SS for me. So as the thread says, how much punishment can a carbon mtb fork take? What are the "limits"? ie: should I stay away from small jumps and rock gardens, or can it handle it? (Remember I am heavy!) Just a sidenote, when I say jumps I mean launching small obstacles and tabletops, and general mucking about on the trails - I am not talking about road gaps - I will leave that for the dual sus!

Ferro Posted May 17, 2017 Share A SH#T Ton of it There was A video on the hub a while back of someone casing a jump with his front wheel(big fella) that niner fork certainly bent quite A lot but it took it on the chinMeaning it will take more or less punishment than a suspension fork then? Something i have been wondering myself lately. Link to comment Share on other sites More sharing options...
Grease_Monkey Posted May 17, 2017 Share Meaning it will take more or less punishment than a suspension fork then? Something i have been wondering myself lately.I have no doubt it will not take as much as a suspension fork, it is after all rigid. I never consciously think of holding back for the sake of my suspension fork, I do however want to guage how much I should hold back for the sake of the carbon fork. From what I have been reading though, the general consensus seems to be to simply use common sense. Ie: don't do a road gap or huck to flat!

RocknRolla Posted May 17, 2017 Share I would err on the side of caution, although it's possible to ride a rigid fork like its squishy counterpart, it is not invincible. I had a carbon fork with aluminum steerer, and systematically I pushed it beyond its limits, till its final catastrophic failure. I have to note that it was not the carbon that went, but the weakest spot on the fork, being the steerer. I weigh about 80 to 90 kgs over the years of (ab)use I rode the fork in places, and at speeds that is better suited to a suspension fork, but the years of abuse caught up to me. I have a great plastic surgeon as well as wrist specialist as a reference as a result.

Glad to hear you are all good now though! When you say you pushed it past it's limit - what exactly did you do? Just rough terain? Jumping around? I will definitely err on the side of caution though!

the nerd Posted May 17, 2017 Share MRP is an awesome fork, you'll be good on that. JC broke his niner fork, he is the one in the video. As you will note in the other thread where he is showing off his new bike you will notice the Niner fork on the front of it! Link to comment Share on other sites More sharing options...

I will be showing my complete build off tomorrow, just need the steerer tube cut, and some small changes then she will be complete! I am so keen for the weekend!!
