Parts and Bikes / Re: Crank arm length

Thanks, I have been reading through old threads about crank arm lengths already. I'm hoping to get more opinions/views on the effect that different lengths has on pedal tricks. I found some discussion like this but still hoping to see if anyone has anything more to offer.

Shorter cranks are both out of the way and lighter. I spoke to a rider that does multiple pedal tricks and he shared longer cranks are better for pedal tricks but he has gotten used to shorter ones(125mm)for the benefit of them being more out of the way. I myself settled on 145mm cranks after using 160mm length cranks for years. I'm using a 20T sprocket and also wanted that gear to feel a bit heavier using a shorter crank because I find it's more comfortable to ride standing.

Thank you, would be nice to be able to try different lengths but it is expensive. I don't find the 160mm to feel "in the way" or anything so I'll probably end up sticking with that length or something close to it.

Parts and Bikes / Crank arm length
« Last post by aliasdck on Yesterday at 05:58:58 AM »
My cranks are old and heavy. They are 160mm FSA crankset with 19mm spindle and weigh like 1276g (2.81 lbs)! according to the parts lists here.


I've been thinking about replacing them with something newer and lighter. Any advice on how to choose crank arm length? I'm thinking of sticking with 160mm because this is what I'm used to.. I am beginning to work on pedal tricks nowadays - like pedal to pedal time machines and other rear wheel pedal tricks - so I do want to put some thought into this before spending any money.


What reasons do people have for going with shorter arms? Obviously on small frames clearance becomes a problem, so short arms would make sense there but this isn't an issue for me as my bike is pretty long with lots of room. Short arms are lighter which would satisfy weight weenies.... But are there any other reasons to consider shorter arms? Or should I just stick with 160mm since I've been riding that length now for many years?


Any insight is appreciated, thanks.

Ive been riding the WTP Utopia with the 20" TT for awhile now, but Ive been really wanting to try an even longer frame. I finally got enough $ together, so last week i bought a DK Phase frame with a TT of 20.8" and a rear end about 0.25" longer than my utopia (13.25" slammed vs 12.95" slammed). So i expected this bike's wheelbase to be about 1" longer then my utopia, and it is. The headtube angle is slightly steeper (75.2 instead of 75) and the seat tube is a bit more mellow (71 instead of 71.5).

I am LOVING this longer frame. Back wheel tricks feel so much more natural for me, the balance point just feels more align with my body whereas on shorter frames balance just feels awkward and cramped especially in tight spins.

So far front wheel tricks feel good too. I thought, for sure, that certain front wheel tricks like jugglers would be difficult with the longer TT but so far they haven't been. Everything on the front still feels good, just going to take a bit of time to readjust for a few tricks but that is  to be expected with any major change. Hang fives and hang nothings feel great, I was worried the seat would feel too far away, but nope. Same with spinning switch handed steam rollers, the distance from the grip to the seat feels perfect. The only trick that Ivee found so far that feels a bit awkward is the karl kruiser, but i think with a bit more practice I will readjust no problem.

I was really worried that going with a 20.8" TT would be too much of a change but it hasn't been and I am very glad i went with it. If you are a taller rider and feel cramped on 'normal' flatland bike then maybe give a longer bike a try. It worked out for me.



I'm tall and mostly lanky, about 6'1" and 180lbs

Frame: 2019 DK Phase
20.8" Top Tube
13.5" Rear End (pegs are hanging off the ends of the dropouts a bit)
34.5" Wheelbase
160mm cranks
Zero Offset Forks
40mm reach stem with 34mm rise (top load)
Handlebars have 8" rise and I have as many spacers as possible underneath the stem (and fork steerer Tube is tall, 185mm)

We will also offer a chromoly frame, fork ,bars and cranks for riders that not really worried about weight. The frame will look like our street frames. I talked to a pro a few years ago to see if he knew a good rider that was available.  Link below you can see how frames will look.

regarding geometry, these topics are kind of old but still relevant to this day I think (what you guys think about that?)

Since you're not established, one mandatory aspect is to have minimum one (well known and respected) flatland rider representing your products, specially since we are on the social media era. As you might know BMX Freestyle is firstly about image marketing wise, and flatland is clearly not an exception on that point.

Hi Tony,that's is interesting to hear!I would say the peak of lightweight bikes is over, but there are still a lot of flatland riders who do take care for weight. Far East Cycles offer some titanium parts for flatland for example.What kind of feedback on design you need? Do you need input for the geometry?

Hello, my name is Tony from Truth BMX.

We are looking to add flatland frames to our race and street frames line. Truth would like to add titanium flatland frames, forks, bars and cranks.
I would like to get some feedback on frame design and to see if there is any interest in Titanium products.
