The Standard Mudguard is made out of PLA and can be attached to your forks by either Velcro (included) or cable ties (not recommended as they remove paint over time). These mudguards work well however are not injection moulded polycarbonate and therefore not indestructible like commercial grade products. I'm not sure they would survive a heavy crash however look good and can be customised with your own design (top and botom). Custom designs are $50 for the first mudguard and $20 for each subsequent print, this is to cover the time required to implement (and test print) your design. If you would like to submit your own design the SVG template can be found here. Design instructions can be found here. Note if you want to simply change the colour scheme of an existing design get in touch, I can do this for you for free. Installation instructions here. The mudguard weighs 27gm (minus Velcro) and takes 40min to print. Please contact me for bulk purchase discounts.
