Welcome back to another episode of Ask GMBN Tech, where we try to answer all of your complex, scary, niche, and technical questions about mountain bikes and MTB-related tech! ⏱️ Timestamps πŸ‘‡ 0:00 - Intro 00:35 - I have a late 90s Specialized Rockhopper with an original 63mm RockShox Jett T2 but lately I have been thinking on replacing it with a 100mm RockShox Recon. How much would in change the headtube angle? 02:09 - What are the pros and cons of tire inserts? Asking for a trail bike with 29" 2.5 tires... 03:54 - My RD-M8000 derailleur with a clutch is rattling too much on bumps. Shortened the chain, the spring looks still, strong but that rattling is so annoying that when I'm going down on serious bumps I'm thinking about my drivetrain falling apart instead of focusing on the trail. Any ideas? 05:32 - I have SRAM GX and if I backpedal on the largest cog the chain slips down the cassette. This is especially annoying if restarting on a steep climb. Is this a chainline issue or is it something that I can fix? All other gears are absolutely fine. Thanks! 06:49 - Do rotors/gyro systems (the thing that lets you spin your bar infinitely) decrease brake power, I am thinking of putting one on my enduro. 07:31 - How much travel do you think I need for doing some proper big jumps and still have a bike that can climb? 09:07 - I currently have a shock stroke of 60mm and I am thinking of going to a 62.5 or 65 mm shock stroke, I have heard over-stroking a bike isn't good but it hasn't really been said why so I am wondering what the downsides are of overstocking a bike is?
