I had the crank for about 8 months. I loved it then a simple 180 off a small ledge removed the peddle boss. That was a sad moment. But in 6 days i had a replacement. good service warranty dept.

rode it for less then a month. somehow the arm got dented and bent? i havent broke any chains or even marked my sprocket. the worst thing that could have done it is maybe a 3 foot drop to flat. only time i left the ground all weekend was landing on a resi. so. do the math 1/1,000,000
im going back to a profile. my last one lasted 5 years -

mine started cracking after about two months, and they make alot of scary creeky noises like their gonna snap. i heard that their were a really bad batch of them though so the people who have been breaking them recently that is probably why. rob wise has never broken a pair, so they must be good

i like these cranks but i think they have a lot of bad batches i've been running mine for about 3 months and everythings good but my friend who got his a months after me already broke both arms and it seemed to be from little hair line stress factors so look for little cracks in the crank every once in awhile if you dont want to die

looks like two taps for the sprocket bolt, I bet thats why ppl are reporting broken sprocket bosses that probably lead to clean breaks. Classic over machining in my opinion.

these cranks were great for about a month. they ride real smooth.
but 3 months i did a 360 tailwhip and my right arm snapped in half.
i dont really recomend these. i recomend the odyssey wombolt cranks.
theyre great so far. -

Perfect for me so far. I got them in 180mm white with the TI spindle and couldn't be happier. They look and feel great. The overall design looks plenty strong to me.

I've had these for 8 months. and the right arm started cracking about 3 months ago. If theres one thing that absolutely sucks in bmx. it's snapping crank arms. and thats what finally happened when i 180'd off a big 6 set.

aww and i wouldnt buy these you may get the odd good pair but quite often there bad because there not hand welded there welded by a machine and often the welds around the sprocket bolts and such are to thin

i had these for two days then 180'd a spine and bent the right one. Luckily i called demolition and they're sending me the medial 2.0's, hopefully these will last longer.


I have these in 180 wit hthe Ti spindle awsome! ! !
Super super light and they dont hurt your ankles, 4 months so far so good, my favorite cranks ive ever ridden, buy em!
