Cornering in the wet?

Postby MTB noob » Sun Dec 09, 2012 11:18 am

Its a simple question but I have never got a suitable answer for it...

When you are cornering in a wet and muddy woodland, possibly a lot of leaves and sticks on the ground, what technique would you suggest to get the most grip on the flat corners? I had a large problem trying to stop my front wheel from suddenly slipping about a foot sideways when cornering.

I appreciate all the recommendations

Thanks :mrgreen:

This might seem like a bit of an obvious and/or unhelpful answer, but avoiding turns on slippery/loose material is the answer.

Small contact patch (bicycle tyre) + loose material (leaves, sticks) + lubricant (water) + sideways force (cornering) = fall off

I'm a roadie, and it's the same for us: you just HAVE to time your turns to be on the best possible surface. Friend of mine came off at 2mph on cycle path when his front wheel caught some wet leaves as he was turning.

Unfortunately the tendency also when the wheel slips is to 'pull' up and this simply worsens the grip.

In terms of getting 'most grip':
1. having the bike in the best possible balance with your weight between the wheels,
2. outside foot down - meaning more weight on it - gets your weight onto the wheel set - whereas inside foot down does the opposite - pushes wheels away from you in a corner
3. start the turn before the front wheel gets onto the mush.

Not sure I can make the problem go away...!

Commit.

If you don't commit, you will fail... stay loose, keep COG low.
Do all you braking before the turn.

Decent tyres and correct tyre pressure helps too.

I have 2.4 Conti MTB king on my tyres and for some reason I like to keep them high at 50psi but I think its because I cant get low enough on my bike. I don't turn before the corner as I have a habit of oversteering and losing my balance simply because I get carried away with speed.

I'm trying to resolve this by cutting the seat post down around 8cm as the lowest setting is 10cm above the frame.

Would this help?

Re cutting down the seatpost - no, if your saddle is in the right place, it's in the right place. If the leaves and stuff are on soft ground it makes no difference - you slide the same without them - if they are on hard ground or paved paths old soggy leaves are like grease.
So either more suitable tyres or you're going too fast.

1. Look as far around the corner as possible.

2. Get low, lower centre of gravity means more grip! Be prepared to slide in the wet, it's natural, just adjust your body position when it happens.

3. Line, best line for the corner, avoid leaves etc.

4. Lean your bike over, but keep your body upright. This weights the tyres in a way that minimises sliding!

Normally I charge people to know that, but I'm in a good mood haha

WAY too high.

Try 30psi.

Yeah, 50psi is way too much unless you're 120kg plus*....you ll see a huge difference just by letting some air out

th eother thing that no one has mentioned is practice, find one and ride it over and over again until you get it. Yes it's boring but it's the best way to improve...

There are a few corners like this on my local loop - off camber rubbly rooty downhill corners

Best way I found to handle them is to oversteer so that front starts to drift/fold. Because you've provoked the drift, it's easier to catch. Repeat all the way around the corner. It becomes second nature after a while and you get used to 'crabbing' round the corner

Stay off the front brake
Lean the bike while you stay upright force it down into the ground
50psi is miles too high try 25-30 give the tyres a chance to deform and grip the ground

Stay loose for the win, used to find this hard as was all stiff thinking it's going to go, it's going to go. And sometimes it did, get loose and it sometimes did too, but less often.

Tilt the bike, but keep yourself centered above it, and low.

Thats the most fun type of cornering. Outside pedal down, push the bike down underyou, weight back and commit. None of this foot out rubbish, it doesn't work. Enjoy the drift.

But until you get that confidence, have the foot ready :D

I think the 'foot out' looks cool 8)

Foot out looks like you don't have the confidence to commit. Feet up looks much cooler

+1, besides if you ride clipped in foot out looks even worse than on flats.....
