When I bought the chiner fork I did check the add copy to see if there were any limitations and none were stated.  But yes, I do now wonder about the big rotor.

And I like big brakes for city riding because city drivers are crazy!

Yeah - that's what I am worried about ....

Agree Cnasta - I have already had a worry about this as well.  I am trying to decide if maybe I should pay the extra for a name brand for the all important forks.

Hi Carbon_Dude.  Yes I know the forks are designed for 160mm and you need the spacer to get to 203mm which I am already using.  But given that, why have niner then put on a limit of 185mm?  Are the 203mm too powerful for the forks? Or is there another reason?

The Niner "RDO" version has 15mm through-axle. On sale for $299....I may have to make my wife mad at me, because this'd let me change my bike to a 19lb gravel racer.

Thanks for this link - I will have to give this some serious thought.  A question tho.  The specs say suits rotors up to 185mm.  Right now I run 203mm brake rotors, fitted with the 203mm caliper relocation mount.  Any reason this size wont fit the niner forks?

Thanks again.

Hi guys, thanks for the responses.  Rock - this did all just happen from slamming the brakes - I did not hit anything.  I was riding on smooth road at the time so was really nothing to hit.

And having a good look at the failure points this morning, I would say what has happened is the left leg broke first upon the heavy brake application, and after it has failed the resulting twist right leg has caused it to fracture at the top.  If you understand loads and breaking forces, you can see that the failure mode of the right leg is due to twisting, not bending. The shape of the fracture reveals this.

It did all happen fairly quickly tho.

Hi everyone.  So I have a bit of an update.

The bike has been going generally quite well, and it sure is a blast to ride.  I really enjoy the light weight of my build.  Anyways, was all good until tonight.







I was only riding about 20 kmh when I had to do a very quick stop so I just jumped on the front brake.  And you can see the result above. A complete catastrophic failure of the front fork.  Luckily for me I did not fall off, but I did go close to going over the handlebars.

Anyways, this fork came from XMI Play.  Are they still around? I am wondering if it is worth contacting them about this. The fork is only 8 months old and has never been jumped or even used that much.

Else can anyone recommend a good robust replacement?

Thanks

Tim

Whilst my wife and I don't race our bikes, we both have 29ers and love them.  In fact she has two - an On One Inbred 29er and a Giant Talon 29er.  Great for getting around on. I do like my IP-057 tho

Well I must admit I mostly ride in the urban jungle so I was building this bike to have some bling factor, along with the 29er tuff stance I like.  Hence the Crank Bros wheels, which I think look awesome.  The rear hub is a bit noisy in it's ratchet system compared to my previous ride, but overall I am very happy. I also like them because they look different to most other wheelsets you see.

Hi Byrt,

the BB was the set that came with the cranks.  Some Shimano ones:

HTH.

Izzy - those pedals do look cool indeed

Thanks for the replies everyone, appreciated.

The tyres are not tubeless at this point as was quicker/easier to just put tubes in.  Having said that, I will prolly convert over to tubeless.

Izzy, what pedals do you recommend?  Because I am a bigger heavier guy (thus the 21" frame) I find some pedals a bit lightweight and not robust enough. Always welcome others ideas tho.

For the colour scheme, was even thinking of just adding some simple detail in red/white to the forks to go with the seat. Just for a bit of balance.  Would like to keep it subtle tho.

Hi everyone.

Just wanted to say thanks for the help in answering my small queries that enabled me to build my bike.  It is really appreciated.

And just to show off the finished project, let me present:



So far I am very happy with how it has turned out.  I am loving nearly every part on it and of it.

It is a fairly basic build with mostly Shimano XT running gear, but it turned out OK.  Weight is around 10.2 kg.

A couple more pics follow.





I was originally going to add some paint or colour, but right now I am diggin' the stealthy black look.  Time will tell.  Only thing that is a little annoying is the internal cable routing (which was much easier to do than I expected) is setup backwards for us aussie builders.  The runs are to suit left hand drive countries where the brake levers are on the wrong sides. But it does work out ok.

OK so got my cables routed really easy in the end.  I did do as I thought and just taped the brake line to the pre-installed plastic line.  But trick is not to pull the line through, but rather to push it through instead, just using the existing line as a guide only.  Worked a treat - dead easy.

So advice from XMIPLAY is to not worry about it.  Apparently all their forks look like that ??

Thanks all for your replies.  Ned, what is this fitting you are referring too.  I am looking at my brake kit and nothing seems obvious ....
