chainring bolt 3d models

... doing so weakens the tool. As a bonus though, if you only ever install your chainring bolts with this tool, the nuts will always be clocked correctly & you'll be able to remove them. ... I will likely call this project done unless mine breaks.

A combined tool based on the VAR PE-35500 (https://www.vartools.com/en/combined-tool-for-chainring-bolts-var-p828.php). The tool does have some limitations. If the nut is clocked at a certain angle, the throat of the tool won't be big enough to match...

Bicycle chainring bolts, 5mm inner length (suggested use - sprockets THINNER than 4mm) There are two files - one for the nut and one for the bolt

Bicycle chainring bolts, 8mm inner length (suggested use - sprockets thicker than 4mm) (this is usually used on thick aluminum freestyle type chainrings) There are two files - one for the nut and one for the bolt

Design influenced by Wolf Tooth's chainring bolts (https://www.wolftoothcomponents.com/products/set-of-4-chainring-bolts-nuts-for-1x). The thread is M8 x 0.75 (see Park Tool's Basic Thread Concepts page). These are a bit shorter than the...

There are two parts to each, the chainring nut which is threaded for the M5x0.8 screw, and the washer which fits on the other side of the chainring and under the head of the M5 screw. To assemble, the nut goes in from the backside of the crank, and...

Standard chainring bolt & nut models, probably for use with double & triple cranksets. A Solidworks model based off of the Inventor model by KsCustoms over at GrabCAD (https://grabcad.com/library/chainring-bolts-8mm). The thread is M8 x 0.75...

Superlight chainring, 4-bolt, 44 T

... chain derailment off the largest ring (essentially a high limit screw replacement). I have STLs for my own use in 96 & 64 mm BCDs (4-bolt) as a well as a test STL in 110 mm BCD (5-bolt). Has countersinks for standard M8 x 0.75 chainring bolts.

46T chainring for 130 BCD. 2mm steel. ...Tried and tested.

Use case: I use a regular (not narrow-wide) chainring in the middle position of a triple crankset; a poor man's 1x drivetrain. I currently use a front derailleur as a measure of chain retention, but I still get rubbing when in either extreme. I'd get...

The chainring holder has printed in threads for a standard M8x0.8mm chainring bolt, so you could use standard chainring bolts, or you could use the printable one I've included. Just like FSA aluminum chainring bolts, the printable chainring bolt has...

Just like FSA aluminum chainring bolts, the printable chainring bolt has a Torx T30 interface which works nicely. For the movement, I bought https://www.amazon.com/gp/product/B014IRHBPW/ (Mudder Hands Clock Movement, 3/25 Inch Maximum Dial Thickness,...

I got a Shimano FC-5603 triple crankset on which I want to install a single chainring for a 1x drivetrain. The stock chainring nut + bolts fix the two larger chainrings (a double) to the crankset. ...The granny gear is fixed with just bolts into the...

However, I didn't want to modify the stock chainring nut + bolts or buy new ones, so I made these spacers that take up the width ordinarily consumed by the second of the two chainrings. ... We'll see if the plastic creep will thin out the spacers...

I have a triple crankset on which I want to install a single chainring for use in my 1x drivetrain. I have the stock chainring nut + bolts, but these are meant to bolt together the bigger 2 of 3 chainrings to the crankset. As such, a relatively thin...

many aluminum guards that are standard are mounted using the same bolts that hold the gear, meaning that you would have to buy longer chainring hardware. this design uses no metal fasteners. The part has four 5.5mm post that extends thru the...
