- Which frame: Bird Zero TR or Dartmoor Primal?
Liking these for a build, determined from literature they’re closest to my riding styles (can’t make much sense of geo charts).
Will definitely take over a year to fully complete/finance.
As someone still riding 26″ and triple chainsets, etc, wanted some input on the +points and -negatives between them in my eyes:
– IS Mount
The looks & price of the Primal almost win it for me, but the sticking points are the axle & brake mount.
My experience of countless bent QR spikes suggests 142×12 as the sensible choice, and tech-wise, seems to be the way things are going so more future proof than 135×10 – yes/no?
I’ve never had IS Mount brakes before. They look wrong. I don’t like! Any reason to stick with this irrational judgement?Posted 2 years agoBagstardMember
The tr is also a lovely looking bike, great geometry, light and strong with amazing warranty and backup. Although standards do keep changing the Hornet does seem a little old fashioned, the 142mm rear axle means I can swap wheels with my full suss.
Have you looked in to cycle2work? That’s how I got me zero.Posted 2 years agochiefgrooveguruMember
The Zero TR is a size longer (medium is slightly longer than the Primal large – but the seat tube is 440mm vs 480). And it’s almost a degree slacker of head angle, a degree steeper of seat tube and 5mm lower of bottom bracket. Better geometry for riding fast IMO.Posted 2 years agochiefgrooveguruMember
Cool! I’m really enjoying my stealthy Zero AM.
Watching with interest as I’ve been looking at both these frames recently.
Would I be able to run some 26″ pikes and 26″ wheels with these without any major issues. I’ll upgrade to 27.5 when funds allow.
I think you may struggle with the bottom bracket ending up too low on the Bird – the fork would need to be 10-20mm longer travel to maintain the angles and the smaller wheels will drop the bottom bracket 12mm+.Posted 2 years ago
