Posted: Mon May 14, 2012 4:41 pm Post subject: Dirt Jumper? |
|
|
My son is getting into the BMX track and I'm getting in the mood for a new bike. My old XC bike was stolen, and my quiver for the past 4 years has been just a townie single speed...
I'm thinking of getting a 26 inch dirt jumper, something like this: (http://www.konaworld.com/gravity_hardtail.cfm?content=shonky) instead of a new XC bike. The idea being that I can have more fun at the track, around town AND I can still have fun on single track, etc.
Thoughts? Are there fatal flaws in hiking the seat up a bit on a dirt jumper and riding it like XC hardtail? Other ideas? |

Is the seat tube is long enough to accommodate a seat post of concomitant length so you can achieve proper leg extension?
Will the seat collar/s/t-t/t-s/s junction withstand the leverage forces from said x-tra long seat post?
Your position on a jump bike with x-tended seat post and no reach stem will not be conducive to epic x/c rides. _________________ DUCKBILLS FOREVER!

What's wrong with getting a used 24XL and waiting a spell before nabbing the new XC bike?
Might as well be Dad and get some quality track time too If yours is anything like mine, you will be plumb wore out every time y'all go to the track or park
Rode a few Cruisers back in the day, they are Pissah for the track....never did learn the park stuff but should have, would've made me a way better rider! _________________ "Moderate is not the new Low" - Chris Joosen, USFS Lead Snow Ranger (Tuckerman Ravine, White Mountains National Forest) |

a DJ bike will not enable you to have the seat anywhere near where it needs to be for XC riding.
The ultra short chainstays and low standover height of a DJ are designed for pump tracks and DJ'ing.
If you shop around, you can get one on sale for $600 with decent quality parts. That's what I paid for my rocky mountain flow.
THen buy a used XC bike (they are numerous and pretty cheap). _________________ "Now is not the time for sound-bites" - David Cameron

just to reinforce what everyone else has said:
DJ bikes feel pretty weird/awkward for anything where you aren't off the seat the whole time... |

IMO you should be able to find a nice full sus bike that will work just fine at the dirt-jumps and still be good for other tasks as well.
Besides - dirt-jumping is a surefire way to get hurt.  |

I am pushing 40 and love my Eastern Nightrain DJ bike. It is a big kids BMX and a blast. I ride mine on 5 mile loops with my kid bunny hopping up and over everything I an able, hit some jumps, ride at the skate park, launch some stairs...whatever. Get it! Check out Transition Bikes, they have a DJ bike (TOP), a 4X bike (full susp.) the Bottle Rocket looks awesome as a compromise betweens lots of disciplines...

I took over a Brodie hole shot from my son which I rode freeride before I decided that giving up free-ride at 46 was a good idea
IME a DJ specific HT is HEAVY, the rims are heavy, the tires are big heavy and the tire patterns are smooth for dirt tracks not knobby which isnt good for mtbing on the trail, the frame is heavy the bike is all heavy period all to take the abuse of DJing
Junior told me when things screwed up he would just bail " let the bike go" and watch it bounce 10-15 ft in the air
Before getting the fully he snapped 3 or 4 square taper BB's and I am sure he could have snapped a spindle on command, he didn't snap anymore spindles but he snapped that fully completely in half |

want one too -- new bike park just went in a couple miles from the house.
i hear you guys on a 24" bike, but at 6'4", and since 29ers are now my normal bikes (SS 'cross, and 4.5" mtb), it seems like a 26" DJ bike would be the right size.
what's the deal with front suspension? necessary? desirable?
i'm planning on keeping it pretty mellow, and mostly riding around with the kiddos, working the pump track and dropping the easier hits / flow lines, which are definitely not optimized for my 29" wheel bikes. _________________ Please don't dominate the rap, Jack,
