Traildonkey 4 is going to be at least a pound lighter than Flaanimal Ti for the frame+fork combo.

We have two options now. The metal bridge works on both Flaanimal and TD3, and has to be manually shaped a little bit on either frame because it is universal, or we can 3d print a bridge exactly for your frame. Just specify which you prefer when you order and note your frame size in the notes section on the address / checkout page.

Howdy! We have not test fit that rack on a Spork. It is possible that it would fit without the offset eyelet kit but it is more probable that the kit would work much better and ultimately make it easier to install the rack.

Hi Bill,

We no longer stock touch up paint for 4.0. The best way to get a close match easily would be to grab some brown paint swatch cards from a hardware store and hold them up to your frame to find the closest match. When you pick a color go back and order a sample size of that color and that would be more than enough paint to last a lifetime.

It does not appear that the axle you have linked would be compatible as the derailleur hanger nut on TD3 is 10mm and an axle is 12mm, so it will not be able to pass through the nut.

It is possible to mount TD3 in trainers that replace the rear wheel (such as wahoo or zwift?).

Flaanimal and TD4 would allow for the use of an axle that threads all the way through such as the linked one.

Absolutely. The sliding dropouts on Flaanimal 5.0 steel and Ti allow native singlespeed use with no special parts or adapters. The same applies to TD4.
