09 diamondback option?
« on: October 07, 2013, 07:31:55 AM »
Hi, I'm new to flatland and a friend offered me a 09 diamondback option, as I research the specs are as follows:

Top tube: 19.5inch
Head tube: 74 degrees
Seat tube: 70 degrees
Chain stay 14 inch
Head tube size 1-1/8
The frame looks like a flatland style frame but would this be a good bmx to add parts and become a flatland style bike? There's little info online about this bike but the specs are closer to let's say the dk opsis does anyone have some info about this particular bike?, I know it's a diamondback but what you guys think?
Thanks!

From the given specs, the diamondback is closer to a dirt jumping/ vert bike, junior-sized, then a full on flatland bike.
that said, if you are just starting out and tall enough(1.75m onwards) most bikes are doable for flatland; just add freecoasters and knurled pegs.
for really good deals, check the for sale section on here. Mostly flat specific parts only, freebie parts if you are cool.
all the best.

Thanks for your response and info, but aren't flatland bikes
Supposed to have shorter frames anyways? I thought
That dirt jumpers are longer frames and not too
Steep angles, if I compare the diamonback to the dk opsis
The angles are the same, the only difference is that the opsis
Is a 19inch frame compared to 19.5 and it's got smaller cranks
But I just need to know if this wil be a good geometric frame
For flatland the rest of components I can swap them

The specs. of the diamondback is pretty mid-skool, early mid-skool flatland at that.
like i said previously, if you are tall enough and just starting out, you probably won't know/ need the differences.
short top tube length don't make a flatland bike...

Yes I'm new to it, I have been riding a 20.5 inch haro for
7 months trying to flatland and I want to step up to a
Shorter frame because I noticed the big difference!, there's a reason
Why all flatland frames are usually short frames huh? And I understand
That top tubes don't make a flatland bike, the angles, and sizes
Of all the frame tubing are made for a different purpose than any regular bike
I guess I'm just gonna order a full bike from the site instead
Of getting the diamondback, but thanks anyways

Have you seen this yet: http://m.youtube.com/watch?feature=c4-feed-u&v=pq8KeGRKtmw
around 4.05 mins in, talks about chain stay length and how it affects handling of the bike.
street bikes have quicker rear end nowadays (13.75"~13.2"), pretty close to where pure flatland bikes are now (12.5"~13.25"), and used to be.
shorter rear ends makes pop-ing into tricks way easier either from the pedals or pegs as they are closer to the axle of the rear hub (pivot point).
shorter and lower top tube makes steamrollers and jump-overs easier; don't have to lean/ bend over as much or lift your leg higher to compensate for the balance point or fear of hooking-up.
the trend for flatland now is kind of leaning towards tech. street style, so its actually doable with your Haro, but do consider stand-over height of your bike, flat bikes generally have lower stand-overs ( 5.5" or less); but like i said- if you are tall, you probably can ride any modern bmx for flatlanding, just get a freecoaster and knurled pegs.
this rider is selling his opsis:

why don't  you try contacting him and make a deal?
