Hi, first post
I bought a 2nd hand (mk1 or classic)Birdy in dark blue last month, replaced the saddle with a Specialized “The Cup Gel”(as they sold out of the expedition gel saddle)
And pumped the Maxxis Birdy tyres to 90psi and went to town on it, 40kph ect.
as well as it rolls I had to change out the tyres, seamed really limited to either the 3 from
schwalbe, or a few from BMX websites...
I ordered a pair of Big Apples and some matching 5a inner-tubes and then waited over a week and finally got them yesterday and installed them today myself. At 42psi (they rated for 30-70psi)
ive had a quick 30min 7k ride tonight and they’re fantastic! Rolls really smooth and compliments the limited suspension(shock absorbing) the bike has.
if anything it’s making me want to try out the wider, 2.2/2.3/2.4inch BMX offerings in 18inch/355 (I really wanted a neon pair of “fireballs” but sold out...)
has anyone here got any joy from BMX tyres on their Birdy?
when I installed the front big apple tyre, I removed the fender-mudguard and even then the fork had a small protruding moulded screw nub in the wheelwell that rubbed on the Big Apple tyre bang in the middle of the tread so I had to put a spacer between the fork and pumped up tyre and then adjust the quick release lugs to sit in the forks sprockets a touch towards the ground as so not to have the tread reach the forks wheelwell nub!!
back wheel was fine, I also removed the fender-mudguard as it is summer after all
Looks like they could easily take 2.2” wheels or 2.3” after I installed the 2.0” big apples, heck maybe even a pair of 2.4”s
regarding suspension, I have the stock medium red PU elastomer, it’s seams ok and not “aged” as I was expecting considering it’s a 2nd hand mk1 style.
but I am itching to upgrade to the multi-s rear shocks, as the interior picture I’ve seen online showing the mini spring and two PU units seam on the money for me, or is the u-design/Urbane Design “adjustable” rear shock better?
Anyways better stop now before I carry on, any advice would be appreciated a lot
