Cheap Mountain Bike Parts | Are these bike parts safe and would you use them?

Are these cheap bike parts worth using? What parts should I buy and test out for you? Look, we all know it's a PITA to get bike parts right now (2020 - 2021). Because of this I thought I would try out some low end (cheap) bike parts. I've have a few I want to show you and more importantly I want to start a conversation on the topic. What cheap parts have you tried and had success / no success with? —— 𝘾𝙇𝙄𝘾𝙆 𝙁𝙊𝙍 𝙂𝙍𝙀𝘼𝙏 𝘽𝙄𝙆𝙀 𝙂𝙀𝘼𝙍 —— https://kit.co/rgmtb​ —— 𝘾𝙇𝙄𝘾𝙆 𝙏𝙊 𝙍𝙄𝘿𝙀 𝙒𝙄𝙏𝙃 𝙐𝙎 —— https://www.meetup.com/Regular-Guy-Mo...​ ⒺⓂⒶⒾⓁ gene@rgmtb.com ⓌⒺⒷⓈⒾⓉⒺ http://www.rgmtb.com​ ⓉⓌⒾⓉⓉⒺⓇ https://twitter.com/rgmtb​ ⒻⒶⒸⒺⒷⓄⓄⓀ https://www.facebook.com/rgmtb​ ⒾⓃⓈⓉⒶⒼⓇⒶⓂ https://www.instagram.com/rgmtb​ —— 𝙍𝙂𝙈𝙏𝘽 𝙏𝙃𝙀𝙈𝙀 𝙎𝙊𝙉𝙂 —— Music by: Robb Quartararo Audio engineering / Music Production by: IG: HB_Audioworks #mountainbike​ #rgmtb​ #dropperlever
