Potentially looking at a Bird Zero TR from the bird site and not sure about sizing ?
I'm 6 foot 1 and normally ride a large however found my last Stumpjumper a bit small even though that was large. Also found a large parkwood to small/short.
The large zero TR has a reach of 472mm compared to the stumpy at 435 ish. So that's nearly 4cm longer !!!
Is this the new modern geometry thing ?
What size do you lot ride ?
Cheers
Steve.
Bird are supposed to be pretty good for test rides and phone advice.
Im about 5 11" and ride a medium TR. its pretty much bob on for me. Where are you located? might be worth seeing if there are any Zero owners local to you.
Based in Oxford. Not sure if anyone round here has one at all ?
I'm in West Yorkshire so not much use. As qwerty said Bird are really helpful.
Bird are an hour away from you http://www.bird.bike/product/book-a-demo/
Jaylittle how are you finding your zero TR.
I'm not finding anything else comes close spec wise for the money.

For some yes.
For others no.
Try riding rather than procrastinating. 😐
Think you've seen the comment on the other thread but really liking it. It's the first hardtail I've had for a while and forgot how fun/capable they are. I did look at a few other bikes including the on one deedar but kept coming back to the TR for spec and looks. Its been faultless and the service was first class. I even emailed Bird one Saturday night not expecting a reply until Monday but got a reply minutes later.
I'm 6' 1" and ride an XL Aeris (486mm reach) with a 35mm stem. It's awesome.
My mate's a smidge under 6' and rides a large, again with a 35mm stem.
The guys at Bird are awesome and will help with sizing / sorting a demo.
I've emailed Bird to see what they recommend
Cheers.

If you're comparing hardtail with full-sus, add 20mm to the reach number for the hardtail to compensate for how sag affects both of them.
I'd guess you're a large on the Zero TR unless you were running a long stem and still feeling way too big for your Stumpy. I'm 5'10.5" and on a medium Zero AM with a 35mm stem and I'd say it's on the larger side for me - with the TR I'd rather ride a small than a medium.
Yeah I've just had an email from Ben saying large would be ideal.
Just trying to de between this or a 29er ragley big wig or whyte 629.
You're pretty close for a test ride Renton. Given the track record you've had with bike fits why don't you just pop down and see what it's like. FWIW I have a Bird Aeris and the guys are awesome at answering questions and giving advice.
I'll give you £800 for it renton, £850 if you get it in black 🙂

Just out of intetrest are there any other Tr owners on here.
Read a review somewhere saying they are hardwork as an all day bike?
Would you agree ?
I'm interested in the new 120 but there are so many sizing options!
I'm 5'11 with short legs and a long torso 🙄
I'm 5'11" on a large with 45mm stem, feels perfect for me. Long legs and short body. Also ride a size large commencal meta V4, which I really like, but wish it had the length of the Bird.

ML I bet. The L is BIG! And I'm the same height but with long legs and would ride an M.
Chief Im not sure I understand what you mean about adding 20mm for the sag?
