I feel it too...
 
I've always liked Birdys, and I am feeling the new GT. The problem for me, though, is that if prefer the touring version with SRAM DualDriveIII hub. 11-34T is simply not enough range for me and my terrain. Plus, plus... I am feeling the Reach GT even more!

Anyhow... anyone feeling the new Birdy GT? Fatter knobby tires, cable/hydro brakes, and 10 speeds sounds more gravel ready than most folders. ...

While I never even tried 3rd party suspension elements on my Birdy, I am very sceptical there is any real advantage wrt purely suspension performance. There may be other reasons though.

The SRAM DualDrive III hub is back for 2018 in the NEW BIRDY Touring 3x8.

But I couldn't find information about the hub or the list of all the cogs. The page only states that the cassette is from Sunrace. I'm curious about their spacing. There would be big jumps somewhere. Alternatively I think it may be possible to fit 11-34 or 11-36 on as small as 16" wheels with a Shimano Zee derailleur which has a very short cage.

Well, yes and no. Sometimes you need to stand. In order to temporarily spike power, or to maintain balance. But that's the beauty, art, skill of MTB; one needs to gauge on the fly how much to lean forward or backward when standing up so as to not lose traction in the rear. Oh, I miss those days!

I found an actual adjustable hydraulic shock for the Birdy from Multi-S. I suspected someone must make a real shock for this bike, but wow this is expensive.

It is stiffer compared to original.

Watch the video on how it works.

Would you...?
 
Would you buy a Birdy Touring generation II with SRAM DualDrive new for $1,350?

I've read the gen3 has over 100 design changes and it feels much more solid. I wouldn't buy a gen2 unless it was $600 because knowing there is something better would annoy me. I never hear of people online complaining about the gen2 though.

So all this hanging around in this thread motivated me to get a Birdy GT. Full suspension, disc brakes, and a reasonable folded size were a new combination my other bikes don't have. Sadly I cut halfway through my index finger while cooking so can't ride for a week. I already swapped the grips and plan to swap the pedals, but will wait for a shakedown ride to decide if the saddle has to go. I thought it would be interesting to compare the sizes of bikes.

Does anyone have a link to a good source for 20” wheels. I have the 9 speed capreo disc brake Birdy. Thanks in advance.

Amazing collection, ttakata73!

Funny.
I caame from a BMX racing background where sitting is extremely rare. Just for a pose in qualifiers as you are well ahead going over the line.
A top rider I knew had his seat high and did sit down around the corners sometimes. He is the only person that did this I knew.

I lack a bike with these characteristics. I have not discounted a Birdy (or Reach). Problem - i already gave too many bikes...

ttakata73, where can I buy a 451 rim or 451 wheelset in Bangkok? Thanks.

Abu Mahendra 02-10-18 05:34 PM

Search for my 'The Bikes of Bangkok' thread. Several bike shop suggestions there. Also look up Wheelsport for distributors in Bangkok.

What is the biggest tire a 406-wheel converted Birdy can take?

mudguard for birdy new classic
 
hey all,

i need mudguard recommendation for birdy new classic that can easily be uninstalled.. i dont really like the looks of the bike with mudguard but need it for this rainy season.. preferably seatpost mounted

been eyeing some mudguard options from zefal, topeak and tacx but they make it only for MTBs

spj 03-05-18 03:09 AM

mudguards
 
For many years (since 1996) I have just used a cut down plastic mudguard attached to the rear with a small L-bracket. Same on the front. Fantastic, and total cost about $5. You can use one sold for MTBs or a child's bike.

ttakata73 03-06-18 11:58 AM

I have a modified Topeak iglow which is designed for road bikes. I zip tied wide plastic panels to fit my 4" fatbike but you can get the idea if this angle works. The clamp is designed for smaller posts and I think it might be too narrow to block 1.9" heavy spray, but you could always add material like I did. Thin Kojaks probably wouldn't be a problem. This is as close as I could get it to the tire. Otherwise just buy an mtb fender and cut it to size. FYI, small tires won't reach an indoor trainer's roller; I was just using it to adjust my saddle.

Does anyone know if its possible to add brazeon mounts for disk brakes to an older monocoque birdy, ideally ird buy the rear suspension arm and front lower cage arm with disk brake mounts from R&M but it doesnt seem possible to order any frame parts from the manufacturer.

The purpose would be to allow 451 20"' wheels to be swapped in as well as to use more aero rims for weekend racing but to return to the standard 18"s for a smaller fold wehn commuting in the week.

Any ideas, some old yahoo groups mentioned steve parry but i cant find any details on him and am unsure if he is still active.
Best Regards Maximus

where do you attached that L bracket? any pic of your bike with the mudguard installed?

thanks for sharing photos, those are the kind that i've been eyeing. seatpost mounted with adjustable arm. need a bit of cutting works but so far it's the most ideal option i guess.

Just out of curiosity, why not using the original fenders?

Question about swap to Sport-stem
 
Forgive the question as a first post, but I recently bought myself a Birdy Rohloff, 2017 model, and am wondering if I made a mistake by ordering the 'comfort-stem'. The dealer recommended the comfort-stem because of my very long absence from bike-riding.
Although I'm enjoying the ride, the best fit I've managed is with the saddle pushed far back on the rails, the seat-post quite high, and handle-bar about mid-point on the height adjustment - just below saddle height. I therefore seem to be sitting too far back, and am finding that I can't ride out of the saddle - which makes the heart pounding steep hills real killers. If it helps, I'm 1.83m (6ft dead), 76.5kg, with long arms.
Q. If I order the adjustable sport-stem (21°) is this installable by me, or do I need the services of a bike shop? The nearest Birdy dealer is an hour away by car. I'm reasonably mechanically minded,and aware that it's an upside down headset arrangement - needed to correct the misaligned handlebar - but my bike experience is forty years' old.
Any suggestions appreciated.
When I've a few more km under my belt, I'll explain why the Birdy was chosen instead of the other 'B-word' :).

UPDATE:
Since posting this, I've made contact with Bruce (bhkyte) and have purchased his Sport-stem, so hopefully this will enable a better fit for me.

The standard or sport stems will both be more comfortable. I test rode a Birdy with a "comfort" stem, and wondered why they even bother to make it.

astage 03-24-18 05:19 PM

Bruce tells me he can ride-out-of-the-saddle on his older monocoque Birdy - although its older Sport-stem has a angle slightly more than the 21° of the mk4.
I'm also hoping I can centre the saddle on the rails. Currently it's too far rearwards and, with our damn third-world-status potholed UK roads, the saddle frequently tips up - even with the nuts torqued well over spec.

Try a different seat post, there are posts which you can adjust the tilt with fore and aft Allen screws, these will not move when you hit bumps.
