Seat post extension

Does anyone know if there's such a thing as a seat post that would allow a saddle to be placed further back? I've got my saddle as far back as it will go and I need a few more inches for optimal comfort. Some bike shops (I'm in the UK) say there is a bent seat stem on the market but I haven't located one. A local bike shop says it can make me one up by welding; but before I go down that route I thought I would ask here. I don't want to change my bike which is a folding full size Rudge Biframe but it would be nice to be more comfy.

Profile Design make one. If your post is steel you could get it bent but more than likely it isn't. Or try a Fizik Arione saddle, it's made for road bikes but the rails are a lot longer, it may not be as comfortable as what you may be after. My suggestions any ways.🙂

Several posts have extreme setbacks, FSA is one that comes to mind.

Thomson also makes setback seatposts where the post itself is bent rather than having the clamp set back off of the post, but either method really just accomplishes the same thing. See:

A few inches is really a very large setback and will severely alter your position in regards to crank placement as well as the handling.

Yeah, it ain't the proper way to get reach to the bars if that is what someone is after.

FSA makes the one with the most setback I've seen - I think it's called "K force".

Sounds to me like your folding bike is too small for you.

Thanks for the advice, everyone. Maybe when I said 'a few inches' I meant only 1-2. It's not so much that the bike's too small for me, it's the way I ride it. I have one of those swivel handlebar posts which is set well back from the norm, so I am in something of a sit up and beg position. This is because I find it comfortable for my neck and back, which isn't the case if I'm leaning forwards as I would be if I hadn't adjusted the bars. Because the bars are further back than usual, my bum finds it needs to be further back, too. I have no difficulty bicycling like this, though I'm sure it's far from ideal for wind resistence. The user friendliness so far as transporation goes makes my folding bike too good to abandon!

I understand fully what you want. I have the same problem and came across the Bromton Saddle Adapter Pin which allows me to place the saddle exactly where I need it. http://www.evanscycles.com/products/brompton/saddle-adaptor-pin-ec009111
I suspect it's quite a common problem for us who ride in a sitting up position. If I go for a bigger bike then I can't touch the ground. If I can touch the ground, then my bum is too close to the crank. The Saddle Adapter Pin solved it for me..

Why do you need to touch the ground while in the saddle?

There's any number of cyclists who are entirely content with only reaching the ground with their toes while in the saddle, and having to get out of the saddle to put their feet flat on the ground. I'd even venture to say that this is considered "normal".

I don't doubt that the bike is rideable - one of the silly stunts we did as teens was riding bikes while sitting on the rack. But it does play merry hell with handling in several" interesting" ways.

If that's really the way you have to have it, try getting hold of a purpose-built crank-forward bike instead. At least it'll still have a sensible weight distribution.

I'm happy if my toes touch. I have a Pashley Roadster cycle, and with the 24.5" frame I can't touch the ground even with my toes. The next size down is 22.5, and with that I can touch the ground with my toes which is just perfect, but when riding, I feel that the reach between saddle and crank is not quite long enough. Shifting the saddle back just 1.5" solves the problem for me, and at the speed I cycle, I'm not too worried about any adverse effects on handling. I've just got back into the saddle for the first time for 50+ years and starting to love it again.

this seat has a good hike http://www.tecnobici.com/shop/index.php?id_product=312&controller=product looks could solve your problem.
