    Reckon we should have a topic dedicated to this as it's easier to keep it in one location than sprawn all over the forum.

    Schwable Big One look very promising in 2.35.

    And a friendly 650b 40mm version;

  • Timed to perfection when considering a swap over to 650b...

  • I'm just waiting for the rain to stop so I can go out and try my new Compass Baby shoe pass extra light (650 x 42) on the CDF. Will report back.

  • Any release date on One?

  • Good use of sprawn!

  • trying to find reasons not to try 650b... Sketched this out last night to see if it would suit my @edscoble like geo:

  • If it's an all new bikes, go for it.

    Make sure it got clearance for 42mm tyres and mudguards, this way if you like, you can just plop in 700c with 32mm.

  • Any idea how a 700x28 compares to going for 650b with either Soma Xpress or something Compass @edscoble

    I have mudguards fitted pretty much perfectly at the moment, but no room to go any bigger tyre wise on my current frame than with the 28mm with guards as below...

  • You got big clearance, 42mm 650b will fit.

  • What I wanted to hear! I'm in.

  • Perfect? I probably can't be botherd as it does not rain enough in London. Which mudguards are these?

    TO answer your question, they're Honjo with home made flap.

    1. Best Front rack for a randonneur bag , for a fork without canti studs but with mid fork bosses?
    2. Best frame pump?
  • Zefal HPX Vintage is the very best you can buy.

    As for rack, no idea, Velo Orange may be suitable especially the one with integrated decaleur.

  • Would you still go for a Zefal HPX over a mini track pump style a la Lezyne Micro Floor? I'm wanting it for tandem touring so it'll be pumping a Marathon Plus to 90-100 psi and the Zefal looks like hard work (but would fit on the pump pegs already on the frame).

  • If you can fit the Lezyne in a frame that is.

    The Zefal is easier and quicker to inflated to 100psi, the Lezyne floor pump is a little bit of a struggle due to it's smaller size and tiny handle/footrest.

    I don't think you can fit the Lezyne on a frame.

  • The lezyne has a clip to put it next to a bottle cage, functional but not as elegant as the Zefal.
    I haven't used either so your opinion is valued,thanks. Probably worth getting a gauge to go with the Zefal too I guess?

  • The pump served as a way to inflated your tyres out in the middle of nowhere rather than something to measure your pressure.

    With tandem, might be worth getting some slime on the back wheel.

  • Oh hai guise. The Schwalbes look kinda cool - be good to have some tread when the snow gets here.

  • So I am basically committed on putting down a deposit on a low trail 650B adventure bike, all happened rather quickly after looking through a random Flickr feed belonging to a German builder... proper thread to follow in current projects but... I just got an email from builder in question saying:

    Are you sure about the rake-trail?  I put it into bike cad last night and I think I needed more rake to get the 34mm of trail.

    The figures/angles I had given him were 73 deg head angle, 65mm of rake giving 34mm if trail... Have I got my angles wrong or is he missing something? I know more rake offset will decrease the trail but my figures suggest 65mm offset equals 34mm rake with a 73 deg head angle... I am no mathematician... thoughts?

    edit - could it be that we are using different length forks? my figs for 650B his for 700c?

    edit* - @edscoble

  • who is the builder?

  • Robert Piontek, Big Forrest Frameworks, he's hasn't done anything like this before but I admire his willingness to experiment and take up the challenge. He's also been fantastic at keeping in touch and can't argue with his prices...

  • ah ha! its the guy who did that awesome fat bike!
    Ed can advice you on low trail and front luggage better. Page him.

  • the very same...
