There doesn't seem to be (so far as I could tell) any mechanism within Kickstarter to offer different rates for international shipping dependent on location, nor to offer VAT inclusive or exclusive prices. Therefore I tried to make an assessment of the likely split of domestic versus EU versus international backers and arrive at an overall price which would hopefully raise enough cash to get this thing funded, and also represent a fair price for the backers of the project. If anyone has a major concern with that I am happy to talk about it.
The Puffin uses 170mm rear spacing, which means a Rohloff won't fit easily. However the good people at Salsa Cycles make an adapter for their 170mm back ended Mukluk. That adapter fits with no interference with the frame at all, overall seems very solid. I don't see any reason a Rohloff hub wouldn't work - with the following requirements;
- QR version
- laced to a rim with offset spoke holes to get the 17.5mm offset and retain some spoke triangulation
- skewer suitable for a 170mm hub
- speedbone or similar brake adapter to deal with the hub torque.
An Alfine won't fit in this adapter due to both the length and diameter of the axle.
The only other IGH possiblity is a 3 speed 170mm hub which is available from Sturmey Archer.
Yes in the fork - no in the frame. A big part of the reason for the great handling of the Puffin is the super short chainstays. Fitting a 29+ tyre would have required stays nearly 1" longer, which would dramatically alter the handling. I do also have drawings for a 29+ frameset in the pipeline - so that could be the next Kickstarter....
The interior of the EBB is a british threaded 100mm wide shell, so anything which fits in that will be fine. So ISIS 100mm, Surly HTII 100, 100mm square taper, E13 and Truvativ/SRAM bb and crank set ups will all fit.
The production forks will use a front standard disc mount, allowing any 135mm ISO disc hub to be used. Hubs built on a rear hub disc standard (eg. Hope, Surly, or any 135mm rear hub) will need to have the brake caliper/adapter spaced across by 4mm - i.e. a couple of washers. This allows maximum flexibility for use of any type of hub.
Yes - as per all the bikes in the Singular range it will have a lovely cast pewter headbadge depicting a Puffin - I'm still working on the drawing. There will be something extra special for backers of the project!
