When a helmet has a crack in it or is over a certain age, it's time for it to be retired.

It's better to be safe than sorry, trust me d00derZ.

Don't die young.

I've been thinking. I want to get a bmx bike but I'm leaning towards a mountain bike. Watched a video and BAM! Guy using like a hardtail downhill or dirt jump frame like if it were a 26" bmx bike. Good idea y/n. Who wants to help? I mean, fuck, bmx tricks and hitting the single track.

I went to the Grotto Monday. There were kids there on 20" and 26", and either would clear gaps just as smooth. No matter what you choose, fit is key. The trend w/BMX is low wide bars and a long frame, which is more of a style thing. A shorter rider should have a shorter frame and narrower bars, and a taller rider should have a long frame and a higher handlebar height (by using a toploader stem). I have a Hoffman, the top tube is 20", and like an ass I shortened the steerer tube when I slammed the stem down (no spacers), so now my only option is a toploader stem. At 5'9" I really should have a 21" frame too. My back is not hacking the low bars and the short frame makes the bike feel cramped. Just for fun I measured my BMX and compared it to my fixed/free MTB and the TT to seat is 1" shorter, as is the handlebar height. So obviously you can get a 20" to "fit" except of course the seat will be down by your knees.

I've thought about a 26" DJ bike, but it's a little cost prohibitive. The obvious benefit would be the ease of riding place to place, which sucks on a BMX, because you won't be sitting down. To have a seat post long enough, the seat would be too high for jumping/tricks (and horribly out of style). I was also considering like an SE Racing O.M. Flyer but the angles are 71 ht / 73 st and I was hoping for something a bit more BMX-y. The Fireman's Texas Cruiser has the opposite problem, long top tube and a slack seat angle, so I think it would be too long. How much top tube length matter when the seat is between your knee anyways? The thing with the DJ bikes is that I don't know that I need front suspension, I still have never owned a bike with it. There are some rad 24's out there, like the new Sunday, and I think S&M still makes one, but for some reason I've never liked 24s, even thought they ride well, and would probably be perfect for my middle aged back issues, compared to a 20" BMX.

Mike Aitken is a good example of why you should wear a helmet while gettin' rad.

wore a helmet. did not die.

I heard. Also heard his helmet has a big ass crack.
At least he gets them at whole sale.

Which cranks will fit on a DA 7400 bb? I had thought that these Sugino RD track cranks would, but it seems that they bottom out and therefore aren't able to spin. The JIS and ISO taper bb/crank interchangeability is giving me a headache. Sorry if this is a silly question.

DA 7400 cranks fit on that.

sounds like the spindle is just too short. never used the RD's and i don't know its taper but usually mismatching jis and iso will only cause like a millimeter or two of difference one way or another.

edit: i guess that could cause them to bottom out if the spindle is the length where the cranks sit RIGHT next to the bottom bracket

jonah got hit. is that what your talking about?

yeah that sucks. is he okay ?

Is it normal for friction shifters to make the chain jump off the chainrings?

no, you need to adjust your limit screws.

That is the most likely possibility... however as a mechanic i have seen this happen with improperly toed front derailleurs and with bent derailleur cages. I assume it's the front since you said chainrings and not cassette.

Anyone tried one of those stems in the picture on the left? Is 230 bucks really worth it?

my answer to both is, of course fucking not

I dont think anybody is saying huf doesnt make good work but you cant say any bike without a 200 dollar hand made stem is a wal mart bike from taiwan. spending that much on a stem does seem excessive. does it really perform better than a thompson or other nice stem thats less than half the price? or perform ENOUGH better to warrant spending that much money? I dont know, maybe, Ive never used one.

I don't think performance is the issue.. The appeal is that it's handmade, locally, and made custom to your specifications. You can't get that from thomson.. you can only get a custom stem from a custom builder and they're going to charge you for it because they have to hand cut everything to your specifications. IT takes a lot of time and effort, hence the price..

If you dont like them, go ride a bikesdirect.com bike from taiwan.

will do!

also there's no p in thomson

But yeah, I love me some Huf but I wont be buying a handmade stem anytime soon.
