Do you ride over cattle grids? The only ones I come across are the ones at Woburn deer park which look fking huge and have flat bars, rather than round. You could lose a small child down them. I chicken out and use the gate. Have never seen anyone take them on a bike.

Who is brave enough? Any tips?

Yes, virtually daily. Don't pedal when they are wet. Hit then dead on 90 degs. No issue.

Regularly. Same as railway lines - ride over them at 90 degrees and you're fine.

Yeah ridden over them loads, as long as you are careful no issues, normally on club rides. If I was on my own I might push across just to be mechanically sympathetic

On the Dunwich Dynamo I road over one coming out of a London park on a very busy main road and both my rear lights fell off into the water underneath the grid!! Not great as I had 100+ miles to ride through the night yet! I had to stop traffic , life on my stomach and fish for them in the murky water!

Road over the one at the bottom of Uffington White Horse 80 miles into the White Horse Challenge Sportive and nearly fell off due to tired legs and not low enough gear!

There are a couple on the ride up Haytor, which I've done a couple of times and hosts the Tour of Britain in a couple of weeks.

One is on an uphill corner, but not a tight one. I don't know whether they will board it or not, I hope so.

If you can coast over them at 90 degrees, stood up with bent arms and legs, you'll probably be fine. If not, sit and pedal evenly.

I'd be a lot more concerned on my Brompton due to the wheel size.

They scare the bejeezus out of me. ! Was blitzing a downhill at 85km/h the other month and realized one was approaching. Nearly burned through the rims slowing down, as the thought of hitting it at that speed gave me the sts.

At that speed, you could bunny hop it, surely?

Do that one regularly. Coming down the hill is worse though, because you hit it at speed.

I'm assuming that above-linked iplayer link is for last week's episode of "An Hour to Save Your Life" with the guy who tackled a cattle grid,. . . subsequently his front fell off.

Last month, my son and I did a cycle tour of mid wales. We tackled a lot of cattle grids. Having experimented, our conclusion was to hit them fast. Much less bumpy. Uphill, getting up enough speed was a challenge, resulting in a painful (for man and bike) jarring experience. Downhill or flat, with enough speed you fly over them, generating a reasonably pleasant "buzz" experience.

We debated, but ultimately bottled, attempting to bunny hop them downhill.

Not saying he deserved to suffer those horrific injuries but who the hell goes riding on roads like that solo in the depths of winter. As for riding over cattle grids, head on out of the saddle weight over the back.

The Brompton feels a bit twitchy, full speed is the only way!

Ha, yes cattle grids and Bromptons, that must require some confidence. I've just bought a S2Lx. Been meaning to post on the Brompton thread. Brilliant fun.

Do the ones on Dorney Common all the time, not a problem if taken 100% perpendicular.

We ride over cattle grids on most rides ... no biggie ... like others have said, just ride straight over at a decent speed ... no pedaling, turning or braking and you just float over them. I know someone who and fell off in the wet, trapping his arm between two of the crossmembers and broke it.smile

Same as, in fact they are fine as they are the flat cross-members, some of the ones in the New Forest are slightly more tricky as they are the old fashioned round type.

The only time I ever had a bit of a 'whoops Apocalypse' moment was coming off the Tumble - hit the grid at about 45 mph in the wet and had a bit of a wiggle, thankfully I 'went light' and the bike righted itself but I think it claimed quite a few victims this year!

Cattle grids are the same as drain covers, as long as you don't brake or steer on them when they are wet there shouldn't be any issues, accidents happen when people over-react to them. Most of the accidents I've seen on group rides have been down to someone getting their knickers in a twist when a double length drain cover presents itself and they either brake or swerve causing an unanticipated ripple effect further down the group.
