Rigid 29er Canti Forks

Doesn't say much for the consistency as mine definitely wouldn't take a 35c cross tyre and was one of the reasons I sold it.

1+, right now it have 28c on mine, but it does look like the max clearance would be just 35c, depending on the manufacturer and model of tyres of course.

the 30c Schwalbe CX Pro tyres fit nicely though, a good size and plenty of grip

It'll be a work bike, not a weekend warrior affair.

Why would you need a work bike, Max?

Lolz

Could always put some 26" forks on for a comedy faux pro effect

[/Jokes]

I like the forks on this BMW, is that the sort of thing you're after?

29er forks will be too long. usually suspension corrected and or course for a much bigger tyre go with a cross fork.

This^

A standard rigid 29er fork is designed to give the same frontend height and HTA, as a 80mm suspension fork.

So thats room for 700mm rims + 60mm tyres + 80mm travel.

You need 700mm rims + 35mm tyres + 0 travel.

So even without looking at actual axle-to-crown measurements you can see you're out by around 100mm, which will lift your front end and slacken your HTA. So basically giving the exact handling change, you state you dont want.

I'd find out what the axle to crown measurement for a pompino fork is and take it from there. My guess is a standard 26" MTN fork would fit better. A cyclocross fork would more likely have the correct rake, and would look better though (IMHO). I have a bonty carbon CX fork and run 42mm tyres, without issue.

Also, dont dismiss forksd because they arent straight, unless this is a asthetic thing you want. The handling effect is a more complex matter.

This is a quality well priced fork IMHO.

Henry, I'm after something straight and more 'industrial' looking. Hard to explain it.
Also the Pompino fork pushes the front wheel out loads, which is something I don't want with the already long wheelbase of the XL frame.

Are you on about the rake / offset? Strait forks still have rake/ offset and it you are replacing a CX with a CX curved or straight it will still have more or less the dame offset. A 29er fork as I already said above will be tool long and upset your head angle too much. Trail is the important feature and depends on both rake and head angle but . The also tend to have a larger off set / rake than a C/X fork "pushes the front wheel out more" than a CX fork.

I have some and have never experienced this.

I have heard a lot of good things about them too.

My cheapo SuperStar 29er forks flex back and forth, but resist twist really well.

I kinda assumed that thats how the worked. Certainly give a slight bit of comfort, yet with responsive steering. So I aint complaining.

Thats what I was trying to say in my essay above.

You want a slack front end, on a rigid off-roader. So can cycle downhill on lumpy stuff, with a bit more stability. I've still gone over-the-bars on mine though.

Oops sorry missed you post. Sf. Great minds and all that!

I'll add to this that many people find a curved fork absorbs more road buzz. I only have curved forks so can't speak from personal experience. So two forks one strait one curved may have the same rake and axle crow height giving the same handling but the curved one may give a smoother ride.

On one rigid MTB 26" fork axle crown 440 mm 38 mm offset

normalish cyclocross fork axle crown 395 mm offset 47 mm

So you iwll have a slacker head angle with the on one 26" MTB fork but there is less offset so that will also increase tail, (I think) best to check with SF tail calculator link.

Also carbon is a better material for a fork then steel.

Sounds right, but these things are mega headache inducing. Best use the calculator, an try not to think about it.

Just to keep my post count in this thread high. The reason you will find most MTN forks have a lot of offset. Is to reduce the risk of toe overlap with fat tyres. Not what you want off-road.

Hours of fun. That's my morning gone...

So even without looking at actual axle-to-crown measurements you can see you're out by around 100mm, which will lift your front end and slacken your HTA. So basically giving the exact handling change, you state you dont want.

This has got me thinking - Has anyone tried using a road fork on a pompino? If the length is shorter it should steepen the HT and ST angles and lower the BB. But would it be enough of a change to make the geometry more road-esque? Or would it steepen the angles too much?

You want a slack front end, on a rigid off-roader. So can cycle downhill on lumpy stuff, with a bit more stability.

You and your sweeping statements :-)
All depends where the bike is being ridden. I live in a very unchallenging off road area and have even used track bikes off road with no problem. I now use a Kona Major One and it is perfect for my needs. The Major one has some pretty steep geometry.
In fact I found the Pompino too slack for my preferences. There'll be no relaxing when I am riding...

Thanks for all the comments and help people.

This is pretty much what I want, but with canti mounts for a 700c rim;

Either that or something in carbon.

I think a 26" rigid carbon/steel (in that style) fork with sliding/adjustable canti mounts is what I'd like.

I was talking with Scott about some Exotic carbon forks that look nice, but I'm not sure whether the brake mounts are adjustable or not.

Oh and I know about rake/HTA but just wasn't thinking straight and dumbed a lot of my first post down (for what reason?!).

Straight forks would be merely aesthetic, as I think the curved Pompino fork looks cack on the XL frame, just like any other curved fork. (Curved carbon would look worse to me)

That and I am just in love with forks in the shape/style of the steel one I linked above.

The exotic jump bike forks would give you a better axle crown measurement but are not V brake.

The normal 26" at 440 mm A/C length are very long.

1+, right now it have 28c on mine, but it does look like the max clearance would be just 35c, depending on the manufacturer and model of tyres of course.

the 30c Schwalbe CX Pro tyres fit nicely though, a good size and plenty of grip

I've run 38c tyres on mine since getting it (not all the way to the back, but pretty much). Marathon Plus right now. Forget the trye I was using before, but it was some cheapo hybrid tyre, I suspect.

can't beat kona P2's, but i dont know if they come in the size you want

Does the XL Pompino fit you alright, Max? Enquiring minds (housed in similar height bodies) would like to know...

Seems to. Only ever ridden one that was a polo bike, but overall the frame didn't feel too small for me.

I don't have a giant reach and provided the BB isn't super high (like on the Cannondale track bike), I don't need the saddle that high.

Measurements all seem ok too.

Thanks, mate. Good to know. Pompino now added to "the list".
