Well this lasted 2 rides after a close call

sigorman85

Here is my rear tyre after 2 rides it was a mavic yksion pro 23x700 I was on a ride after work and was hammering it down a hill at 38mph next thing I see is a car around the corner braking hard so I slam on the anchors as the car was get close quite quickly the rear wheel locked up and the front was twitching I had time to think it was hit the back of the car or ditch the bike in the stream luckily I stopped about a meter from the rear so lucky but £45 down the pan in 2 rides oh and it must have been the longest skid ever on the road not my boxers I would say 100m give or take anyone else's one this or similar ?

Agreed its just a wheel, better photos maybe? if its just a tyre get over it it could of ender much much worse!!

trashing a 45 quid tyre after two rides is a bummer

i lost a strip of rubber off a quite new pricey tub after hitting gravel and the wheel locking, it's annoying

There's nothing wrong with the wheel, as I understand - the OP said that the tyre was ruined, which is clear from the photo. But I agree that while it's annoying, it sounds like it could have been worse. At least you weren't hurt. Also, you can get those tyres cheaper than £45!

I know we are from Dorset, but any chance of some punctuation!?

It's not bulging it'll be fine for a few more miles at least!!!!

Probably best not to go hammering down hills if its not safe to do so ?
I think you got off lightly ?

goonz

Very lightly. Wouldn't complain about a tyre when it could have been so much worse. Oh and yes please put at least one full stop somewhere in that mega sentence. At least one, my poor lungs couldn't keep up!

Agreed. Racing on the roads is dangerous.

There is a reason why bikes have front brakes...

Wow, tough crowd.

I think you need to work on your braking technique, but glad you got away without injury.

Oh and you're paying way too much for tyres

Last time I locked a back wheel up into a skid was about 20 years ago on a bmx.

I remember doing that as a teenager. Hurtling down a hill in the Dales when a horse appeared and started rearing sideways across the road. jammed both brakes on and the back wheel must've locked cos the tyre ended up looking like yours. I concluded that adrenaline is brown, but smells of burning rubber.

Considering your options were lose the bike in a stream, or slam into a car, you got off well. I would have been so happy the only problem I had from that situation was a shredded tyre. Had a situation similar to this, but it was a rider who went down in front of me. I could have run him over, gone over the edge of a cliff or slam into a cliff next to me, so allowed my bike to take a beating as that only costs money, which comes and goes.

This. Skidding will dramatically lengthen the time it takes to stop compared to hard controlled braking.

I suggest a GP4000S next time, grip is great, you can get them for about £25 and I'd be surprised if you could get through that in one skid. Really lovely thin race tyres like Vittoria Evo's and Veloflex (and presumalby these Mavics) really won't like being locked.

That said, glad you missed him.

Jesus Christ I wasn't looking for a sympathy vote

they're probably all grumpy because of the weather

it it were warm and sunny it'd be different (no responses at all)

You'll be amazed how much can be applied to a front. of course the rear will unload (increasing the risk of a skid) as the front loads up. You may already be an expert with your brakes, but if not its worth reading up on technique..

Motorcyclists learn a 5 point system.

1 Shut off the accelerator.
2 Apply the front brake.
3 Apply the rear brake.
4 Increase the pressure on the front brake.
5 Apply the clutch to avoid stalling (on a manual).

steps 2-4 apply to a bicycle. The reason you apply the front in two steps, is because you cannot load the front up until the mass has transferred squishing the front tyre and increasing the contact patch. You also cannot apply more on the rear for the same reason.

obviously motorbikes have suspension and much larger contact patches, but the increase in contact patch size is broadly similar and the compression of the front suspension does little to effect the transfer of mass.

Or you could have bunnyhopped the fallen rider then stopped to help if that was your plan....

If the rear wheel locks up, you should try cadence braking...release the brake and reapply until the wheel locks then do it all over again - rinse & repeat until you stop. This is exactly how a cars ABS system works. Also, the front brake should be doing most of the work, as that's the wheel with all the weight over it when you're stopping.

And check your boxers. Like your tyre, they can only take a certain amount of skidding before you should trash them

sigorman85

Ha brilliant mystique hopefully I don't put my self in this situation again but I will give it ago cheers for the info

I wear my brake pads out rather than my tyres but that's because I'm a bit of a woos and really don't like going down hill fast... I ride on the basis that there is always going to be something big and scary just around the next corner and if I can't see ahead its potentially not safe. And surprisingly often I'm right on the country lanes here in Cornwall. Shame about the tyre but thank goodness you survived
