Re: seatposts with long layback

reohn2, forums are about sharing experience and information. Not everyone is going to agree with your opinions.
I hope that thingy you bought from SJS solves your problem. If it doesn't, we now all know a £1550 bike that supposedly will. :D

Re: seatposts with long layback

Morning Colin, you're up bright and early. Lovely out there today. Hope it lasts thru the weekend!

Whether you think an 11mm difference in layback is significant is a personal opinion. For anyone who thinks it is significant and is ruining their cycling, they can easily get hold of a seapost that compensates for the difference. SJS is not the first, nor the only, company to sell a seatpost with more layback than normal. As you admit, they can get this inexpensive and simple fix and try it for themselves.

End of. :D

You have a very sensitive derrière.

Re: seatposts with long layback

"I've seen people claim sensitivity to as little as 2mm"

I sort of doubt it.

Re: seatposts with long layback

People believe all sorts of silly things.

BTW, you can easily determine the exact difference in saddle layback with different seat tube angles using very basic trigonometry and your own preferred saddle height.

Re: seatposts with long layback

Hmmm.

I'm a bit shorter than you at 5'7" and so have my saddle a bit lower, but I did the maths and the difference between a 72° seat tube angle and a 73° seat tube angle in my case comes out to a whopping 11mm.

Rather than spend £1550 on a new bike, I think I would first experiment with one of those £25 seatposts from Thorn claiming to offer 40mm of layback if I was really convinced this miniscule difference was significant.

Re: seatposts with long layback

Another shameless Spa plug... :lol:
Does seem great vfm, but looking at the pix on the Spa website, the Brooks B17 on the Dawes seems to have as much layback as the saddle on the Spa tourer. Probably impossible to tell for sure just from pix of course, especially when the difference is presumably just a few mm. So Colin what Is the actual difference in terms of layback with a Brooks B17 between the Dawes Galaxy with a 73° seat angle and the comparably sized Spa tourer?

Re: 80's Dawes Galaxy - Upgrade or Too Old?

+1 to above.
There have been problems reported on various bike forums about IRD freewheels. Supposedly their current mk IV version has sorted it out. They're also very pricey. You can also still find cheap and adequate Shimano freewheels if you trawl the Net. Suzue does a decent 126mm threaded rear hub easily available in the States but maybe hard to find in the UK? Phil Wood also does a 126 threaded rear hub, also easily available from the States. Very pricey but will outlive the Dawes.

Re: seatposts with long layback

The problem, as far as I can gather, is that either some people are using Brooks saddles, which due to the way the rails are made, don't allow for much layback, and/or they have odd physiques.
Or maybe some people are just plain odd. :lol:
Or just like to moan. :roll:

Personally, I've never had a problem with Brooks saddles and my bikes, but maybe I'm just lucky. Years ago when Greg Lemond complained about this problem with racing bikes, I once bought a plumb line and followed his advice about how to set up the saddle for optimal layback. I think, though, he had unusually long thighs. Ironically, his remarks about standard racing bike geometry in the 1980s is exactly what some people on here have been moaning about concerning current touring bike geometry.

If it's really such a problem for some people, seems there are some cheap easy fixes like that seatpost or the other thingy Thorn sells.

Re: seatposts with long layback

Oh, that thingy.
:idea:
It would look pretty weird but you could put the two together and get 80mm. :lol:

seatposts with long layback

I have a strange feeling this topic has been done before :wink:
but has anyone actually checked out one of these Thorn seatposts:

claims to have 40mm of layback :?:

The Vaya, hmmm. Its geometry is vaguely reminiscent of a certain 29er. :roll:

Re: The dilemma and search....

roughstuff eh? the answer is blindingly obvious.
Get yourself an old MTB. they go for peanuts. fixated with 700c? get a 29er.
you know I am sure that the seat tube angle often slackens with increasing size and you can always further correct saddleback with a different seatpost.

edit: have you seen the lovely 853 Genesis frame in the classifieds? No connection with the seller btw.

Re: Should a new brooks saddle look like this?

I've had a few Brooks saddles over the past 30-odd years. :shock: :lol: Judging from your pix, I would guess it's only cosmetic and will not affect the use of the saddle. Only a guess, though.

However, if you want to get a refund and don't have any luck with the retailer, try contacting Brooks directly. You never know, but I suspect Brooks is rightly proud of their fine workmanship and may be able to help.

PS: there is an English translation of the terms and conditions on the retailer's website.
