Enduro/gravity bike suspension and geo


Recommended Posts

Posted

I'm not gonna pretend I'm a very good rider. But I can in all honesty say that I do notice small changes - half a degree head angle here, degree STA, 10mm on a stem, 10psi in a shock. It's not gonna make me faster necessarily, but I can honestly say when I get it right I do enjoy my bike alot more.

 

But I get not wanting to faf over that stuff and just wanting to ride. For me, a big part of my enjoyment comes from tinkering and faffing over geo/suspensions/components etc...

That's me. Fork offset, Q Factor, Suspension kinematics* it's just noise to me.

 

@Myles I'll be interested to hear your views on the narrower rims. Personally I think the performance difference between 28 and 35mm won't be noticeable but the stiffness between Ali & Carbon will.

 

*Is it just me that hates that word?

No, not just you. ????

 

I'm not sure if I'll be able to tell what difference each of the 2 changes makes on their own, to be honest. If I did one step at a time, yeah, then I'd be comfortable with saying I'd be able to tell what each change (Alu to carbon; 35mm to 28mm) makes. But that would be reeeeeally expensive.

 

But both together? Nope. Will still be interesting, though!

All of them differs on the lowers, not the CSU. It's the part where the axle goes through where they build in the offset.

 

CSU is standard across all models of a fork for MRP/Fox/RS

​Is jy seker?

This article really makes me think it's the CSU that determines the difference and the fact that if you buy a new CSU you have to select the correct offset.

Lyk my dit is die Crown met Fox.

 

MRP is defnitief die lowers. Gaan seker maar af hang van die verskafer.

 

Did a bit of digging, seems like with MRP and RS the lowers can be changed, with Fox the CSU must be replaced. From my understanding anyway.

I was the same, had my settings on Evernote and would toy around a little.

My home dynamic has just changed so I don't ride as often as I want so now I just ride.

I do believe I have a good base setting. I also don't push as hard as I used to as I can't afford to be injured and off of work.

There was a rim width comparison a while back. Basically up to 31mm no real difference.

Interesting comes with alloy vs carbon. 31mm internal is widest for alloy after that its carbon territory. Something to that effect if I remember correctly.

The big difference, to me, is how a simple deg or two can make the worlds difference in confidence. On sections one use to hang on for dear life, one suddenly starts looking for even faster lines or ways to gap stuff. BUT, One eventually gets use to that too..

 

My 2 C, (and its just what I've read) Is that to big a taboo is made of the offset and that even to the pro's the difference is almost negligible.

Now that I am pretty used to my fornt tyre I have been experimenting with rebound front and back. I've noticed that some pro's seem to ride with very fast rebound, in some cases, full speed. I've always erred on the slower side, especially where proper jumps are involved. Since most of my riding involves higher speed descents, sometimes rocky and without any big jumps, I decided to experfiment a bit. I have been riding the fork with just one click away from full fast and the rear, about 5, only because the adjuster seems to make less difference. Its still very fast by my standards. 

 

So far, it seeems to be good. On faster bumpy descents, it feels very good and pumping the bike elicits a very nice response, making unweighting and hopping over stuff even better. I imagine that on bigger jumps my timing will have to be spot on. More riding and experimentation required.

 

On a painful note, out on my HT this morning the rubber didnt stay down and and I have a rather bruised hip, knee and a bump on my head. Something about switching to a twitchy 26er frim a tank like Enduro may have played a role...

shortly before my full squish frame died I started doing exactly what you are with the rebound being sped up, and it really made a distinctive change, and for the good I recon.....the bike was more responsive and felt more supple....recon that I had too much slow rebound and the shock was packing up at higher speeds.

 

now with the LT hardtail I have the fork set up rather well, but the rear suspension feels lock out all the time :P

What u get?

I went a bit more simple Jack than I wanted to, but the price was right.

 

Vitus Escarpe 140mm 29er.....

 

It seemed to get good reviews and has numbers that were a bit slacker than I wanted but according to reviews didn't make the bike less 'fun'....

 

https://www.mbr.co.uk/reviews/full-suspension-bikes/vitus-escarpe-290-pro-2015-review

 

It beat a couple of decent bikes in the test pool so I figured it can't be 'bad'..... Time will tell.

 

I need to find a boost hub for the rear now. Then I can build the wheels and get the parts onto it for a good thrashing this weekend.

Nice bike, did you get the orange one, complete bike or frame?

Very nice! 

 

The Escarpe was also on my short-list a while back when I was looking for an AM rig (albeit this was pre the 29er AM rig boom, so was looking at the 650B).

Frame and shock...

 

I have all the other required bits to build up a decent bike but will need a new boost rear hub and headset. 

 

It's the black and blue one... Same as the review frame. I think the orange one was 2017? I'm not sure. 

 

I landed it at under 9k, ordered Thursday night and arrived at 8am this morning.

 

Thank you DHL!

 

Should have it ready for a hack around Jonkers on the weekend.......
