Any question answered...

doesn't that feel weird having 1 foot move more than the other?

also what hoefla said.

but you have to swop the cleats around to get the variation, so you can't have different between left and right...

I'm not sure I get it.

My cleats can be swapped round for different float - they're asymmetrical.

My left unclips easily, my right can be unclipped easily to the inside, but to the outside it needs wider turn than the left. Good on my knee.

you can turn each one round? on atac you swop right and left. but they are individually always the same way around. if you see what I mean. god this is exciting.

I think it's all the same. It can't be any different. You can either have an early release or a late one - depends what shoe you fit the cleat with dots on.

A question to do with Optics:

As the iris of the eye gets larger to adjust to low light levels. Why does this not create a very shallow depth of field for our vision (or does it?).

It does. Wikipedia seems to be a bit confused about whether the maximum aperture of the human eye is f/3.2 or f/2.1 http://en.wikipedia.org/wiki/F-number#Human_eye but you might not have noticed because it has to be pretty dark for your pupil to expand that much.

And for animals who can really adjust their iris's from pin point small to very big (like cats) do they get a change in focal lengths?

Focal length is a separate thing from pupil size. The only direct link is if the expanded pupil allows light into the eye through the edges of the lens which might have a different focal length to the centre, making it impossible for the eye to focus perfectly. The edges could contribute more light to the image than the centre, so in that case including them could change the effective focal length of the eye.

I think the animals with non-circular pupils are interesting. By contracting their pupils to a vertical line instead of a point, a cat probably retains the distance clues from limited depth of field even in bright light. I wonder if that's an advantage to them, or just a side effect of the mechanics needed to allow such extreme ranges of pupil area.

Are there any decent sealed 126 or 130 spaced rear freewheel hubs that I'll be able to run 7 speed on, that would be suitable for long heavy miles (lots and lots of miles...) and not cost a fortune?

I think the one with the L goes on the left shoe. The one with the R goes on the other shoe.

I don't think it's about float. Time cleats are asymmetrical so they only unclip outwards or something. But I have no idea what I'm talking about

It's the "not cost a fortune" that scuppers you. DiaCompe's retro ENE line includes hubs, £65 r and £60 f, which will presumably be similar quality to the Gran Compe track hubs, but as you'll doubtless have dismissed Phil at just over £160 for a pair, £125 for a pair of hubs might be approaching your idea of costing a fortune.

Correct. To get a 'firmer' release with Atac cleats you put the L on the right shoe and the R on the left shoe.

Didn't realise the Phils were only £160.... I was kind of hoping for something around 60-80 for a pair, but looks like it will be the Phils, as I'm planning on doing quite a few 1000 miles on them there's no point in skrimping for the cost of a night out.... While I've got you, what would you reccomend for a 700c rim to take the abuse of a long tour, on vaired surfaces? Have been thinking Mavic or Sun, but open minded really...

Probably 32 or 35c so rhyno lite may be a bit wide? need to have a read up methinks...

CTC types seem to like the Rigid Andra CSS

Probably 32 or 35c so rhyno lite may be a bit wide?

32c tyres on Rhyno Lites will be wider than the rim, and hence fine.

can anyone recommend one in clapham or one who would be happy to work there?

i'm after having a built in cupboard made in my house.

But that means it bloody doesn't matter where L and R cleats go as it's a matter of personal preference. Geeee...

Pretty sure 35-47mm is the recommendation for those.

You're new here, so you probably haven't noticed the many previous discussions, with working examples, about the modern approach to matching tyre and rim widths.

Feel free to chip in if you've actually used 32c tyres on Rhyno Lites and been disappointed, but if you're just going to quote manufacturer/distributor recommendations which are based on outdated thinking, you're not really adding anything worthwhile to the conversation.

But wait, my experience is meaningless as I am new to the forum.

Your experience has the same value as anybody else's, your previous post was the thing that was worthless.

Now make your anecdote really worthwhile by telling us which 32c tyres you were using on your Rhyno Lites, at what pressure, and for what kind of riding.

tynan sells skid patches.

also look at these.

They're great, mine have really lasted

I bought a full 360 degree skid patch off him, it was one of those that goes all the way around the tyre, kind of looks just like an old worn out tyre to be honest, but it skids really well.

And as a favour he took my old worn out tyre, said he would dispose of it for me.
