Fitting Bmx Cranks on a Fixed Gear

Fitting bmx cranks on my Mash Reyes Fixed Gear! I have always wanted to try out bmx cranks on a fixed gear, and today I fit some spline drive profile cranks on my mash slumworm reyes. The bmx profile parts all link up nicely now, let me know if you guys have ever run bmx cranks on fixed, keen to hear your experiences!

Specialized made a bike called the Pfix and it used a very similar crank and sprocket setup. I ended up swapping them for a set of odyssey thunderbolts which are a unique 2 piece crank design. To answer your question, yes I’ve ridden BMX cranks on a fixed gear bike and those chromo 48 spline inserts on the sprockets are prone to play over time which is why I switched to bolt drive!

Love this kind of vid where you speak a lot while keeping a nice 'n chill atmosphere!

Waveywheels on a dark winter morning in AZ, it's a good day. Thanks for the post.

I'm a fan from Philippines since your day 1. I watched your other upload just to wait for your another content. Love all your work 🥰

You will toast those BB bearings if you leave them like that. You need about a 0.1-0.2mm preload, but you have a 0.8mm preload with that BB width and crush tube combo. Either slim down the inner crush tube or space out of the BB cups by 0.7mm etc.
I've lost so many hours messing around with BB spacers. Long live Shimano hollowtechII and OG BMX cranks

Like the added crankset and overall bike set up!

Dude, that looks so rad! I remember sporting Profile cranks on my PK Ripper back in the day; and I mean back in the day(circa 83)! Back then their fit and finish was second to none. Profile has been around for a long, long time, considering. It’s nice to see that quality still shines through!

Profile spline drive is the shizzad. Absolute baller stuff!!! Cheers from New York

Always interesting and cool, but everything is interesting to someone from the Tron.
love the Tshirts too, will grab one in the new year. 🎉

As always such a Nice Build! Actually nice to see how that works :) Greetings from Berlin Germany :)

[CharlieMetcalf]

AWESOME! Thanks for this, I have always wanted to do this myself, and was not sure how they worked.

Looking good I enjoy bmx cranks on a fixed. Don’t have a preference but have a few with both bmx and not.

been running profiles on my MBase "stylin" frame for a decade now, and I'll never go back. So nice in 165mm - tree lite spline sprocket

I primarily ride spline drive fixed 🔥 Its such a simple and robust system. I've never successfully taken off and put back on a different crankset so easily

I ran profiles on my track bike back in 2015/16 and the first thing you’ll notice is the rigidity. They’re so damn stiff which being a bigger dude felt amazing. I had the imperial chain ring on them which looked dope to. Nice work on the set up bro, they look amazing on your bike. Definitely try find the 165’s if you can. The toe overlap will be that little bit less but you’ll notice it. Big ups mate.

Great Video! Where do you get your parts (specifically frame) for your videos?

[Chogie]

Love it. Any excuse to tinker away and try something new 👏🏼👏🏼👏🏼

My favourite part was when you took off the omnium cranks.. and put the profile cranks, bb, an sproket on like a top dog.

Hi man, been a fan of your work, I've run a BMX Profile setup on my All City Def Wish for quite some time just to commute without the stress of FGFS and it definitely develops a play in the long run. Ideally, it should run on a track 144 crank setup but the frame wouldn't allow it. I'm running a 33-9 T gear ratio at the time.

I believe the main leverage this Reyes frame had compared to an old-school FGFS frame like my Def Wish is its capability to run that track 144 with a big chainring setup for reliability.

Sick build as always though.

Splined cranks are mandatory on a fixed gear freestyle 😁
