So after bending two p.2 frames and hesitating to buy a chromo setup, I dove in and got the new Blackmarket Mob. I'm stoked on everything except the cranks. It's hard to find a set that fits, but other than that, I couldn't be happier. I think I'm sticking with Blackmarket from here on out (thanks to S&M).

nice ride.

are you going to lower your fork

or do you like it tall.

 

[blackmarketg4]

i've only ridden it at this height. would lowering it give any benefits to stability?

 

[EOBF]

Very nice bike indeed.

What trouble are you having with the cranks?

What trouble are you having with the cranks?

Well, I'm running profile BMX cranks. I had a 5 3/4" spindle but the arms had almost no clearance from the chainstay. The arms were only receiving half of the spindle to give about 1/8" clearance. Now I've switched to a 6 3/4" spindle and have adequate clearance, but I have to run a ton of spacers to make it all work. Maybe Carter designed the frame with a specific crankset in mind, and I'm positive it wasn't a Profile BMX deal. Don't get me wrong, I got it to work and it's tight, but as for the proper fit... it's not there.

lowing it will make it harder to manul
and decrease pedal overlap

but

it will have better pump for jumps and
be a toiwt ride.

lowering the fork gives you more control. right?

6 3/4" spindle?? 6" is what most guys run on mtb's with bmx cranks.

When I ran the 5 3/4" I had almost no clearance, and with the 6" it would have only given 1/8" more on each side, which is why I went 6 3/4"...

lower the fork. it will handle better. the blackmarket stays are super short anyways so i mean it will be easy to get use to

What's a good height to run?

 

[Mr Tiles]

80mm would work

thats what my bro is getting on his mob

i have almosy no clearance to the stays on my ToP with the 6" spindle.. and the arms arent all the way on the spindle either. not probs at all, and most guys run em teh same way.

you should be able to get away with a 6" spindle. you're not supposed to have tons of space between arm and chainstay. 1/8" sounds like enough

btw sick frame and build. lowering to 80mm sounds good

nice bike

 

[scurban]

really nice set up. Lowering your fork to 80mm should help alot.

Are the 2003 DJ1's adjustable?

 

[scurban]

If you know what you're doing, all dj's are adjustable. take off the lowers, add in some negitive spacers (110-80 =30, so 30mm spacers) and you have yourself an 80mm fork.

talk to brad he has lowering kits or use lax stick (first idea is safer)
