Picture say a thousand words, but if you need any info just ask

Cost ~£60 complete

Andy, I though you were gonna build them for us?

Time it took, I've got better things to do. Get down to Screwfix, tool up

I keep thinking something like this may be an option for the front wheel

Possibly easing stress on the headset and wheels. I've never been a fan of the rigid front end on the bike when using trainers.

Do I have to wear overalls to gain entry to screwfix? Or do I do a Lee and wear shorts?
I like the full length or split versions where you ditch the front wheel and the forks are held on a rocking mount to follow the sideways movement from the rear.

I'm trying to work out how I'd integrate one of these

into a rocker plate solution and not have a rigid steerer


@bobinski

Shorts are required

Looks great - like the tennis ball damping !! Thought about one myself, as I'd just need the pivot and tennis balls as I've got loads of timber. The only issue is getting on and off is hard enough on a normal turbo since I broke my back - I'd need a step.

It's one of the reason's my MTB has a dropper seat post !

Do we think that these will help with soreness in the nether regions from long rides on the turbo? While I can ride for 2 1/2 to 3 hours on the turbo in one stint, it does start to get uncomfortable, while a better saddle / shorts / pad have made some difference it's still not as good as IRL. If this could help then I'm all for building one asap.

Yes, it will. I suffer the same issue and find I need to stand more with multi hour turbo sessions. This is the probably the most beneficial aspect. Mimicking outdoors is a nice feature. I will have a hundred miles by the end of the week.

Time to get my Sketch pad and tape measure out then ... going for a full length one if I can get the cutting plan to fit on a single sheet of 8 by 4 ply

 

[CXRAndy]

It will easily fit one large sheet, the main cut is slightly diagonal to make a narrow end for front wheel and wide part turbo end. Post up pictures when you've done it

I made one with barrow inner tubes for suspension and I get a lot more movement than you do. My advantage is that I can adjust the pressures. I would say your set of balls need to be nearer the center and also possibly less of them

The front support is fine, the wheel easily rocks from side to side as it's just resting there

The initial feel seems about right, especially standing. I thought about having the balls slightly angled as opposed to parallel to pivot, allowing graduated pressure as more lean presses on more balls. Its all an experiment to get the right feel, for now pleased it rocks slightly, hasn't collapsed or I've fallen off it

What sort of size Inner tube and how many ... I guess it depends on if you are doing a full length board or just a half one
