Mountain Bike Anatomy (Mountain Biking Series)

Mountain Bike Anatomy

Today I will begin a mountain bike series, finally moving away from hiking. This post will cover the parts of a mountain bike and I will post some pictures so everyone can see the part before we move on to other aspects.

The Frame

The first part of the mountain bike is the frame.  All other parts of the bike attach to the frame.  Frames come in different materials like steel or aluminum.  In addition, frames come in various angles, which influence what style of riding the bike should be used.  Making sure your frame is the right size and a good fit is one of the most important parts of comfortable riding.   There are is a science about sizing, but one of the keys is a slight bend in your foot when at the bottom of a pedal stroke.

Wheelset

The second big part of a mountain bike is the wheels.  Wheels attach to the frame and come in various sizes from 26in to 29in.  The wheel can be further divided into rims, hub, and the tires.  Rims are the metal portion of the wheel, come in various widths, and are made from different metal alloys.  The weight put on the rim is distributed using spokes, the little metal bars that that crisscross the inside of the rim.  Spokes are held in place using “nipples”, which are metal tubes that connect the spoke an rim.  The hub allows the wheel to freely spin around the axle, which is attached to the frame.  The rubber part of the wheel is the tires.  The tire has little nubs that provide traction.  Tires can be inflated with an inner tubes and many are now “tubeless”.  In addition, the degree of tire inflation can affect how smooth the ride is.

    You did not mention type/brand of bike you own. Where do you ride? Nm

      My current mountain bike is a 2012 GT Karakorum. I actually haven't been able to ride any trails since moving back to Texas, but I am going to the Mission Hike & Bike trail today.

Trip Report: Trip to London Part 2

London: Part Deux This is part 2 of our holiday trip to the UK and London in December 2016 and January 2017. Make sure to check out our London trip part 1 and here is a little background info as a reminder: Travel Agency: Go-Today Flight: Delta Airlines Destination Route: Austin to Atlanta to London Return Route: London to New York to Austin Hotel: London House Hotel Day 3 (Continued) So last I wrote, Jarrett and I had returned from Bath and Stonehenge.  It had been a long day, and we were EXHAUSTED. Yeah, that’s right.  I’m a millennial and I capitalized a word, because I cannot put enough emphasis into how exhausted we were, particularly me. After a nice dinner at a tiny Moroccan place near the hotel, Jarrett and I headed back to the hotel for a “nap.” It was too late for us to try to get any tickets to view the celebrations by the Thames; the city limits the amount of people that can attend those celebrations with the fancy fireworks, and you have to get

Tubing Down the San Marcos River

Tubing Down the San Marcos River Linda here for Adventures with BeeGee. We’ve been adventuring more aggressively since Salkantay. My goal this August is to continue the adventuring while catching up on blog entries to ensure we preserve these great memories. On Saturday, July 20th, Jarrett, a friend of ours, and I went tubing down the San Marcos River. I realized I had been living in Austin for almost four years now and had not done this iconic Hill Country tourist activity. To be honest, we probably had not done it before because I only learned how to swim last year and am not the most comfortable with water. The San Marcos River is relatively shallow and the heat in Texas is unbearable, so if you want to enjoy the outdoors but are uncomfortable with water, this is a great option. The water is initially cold, but once the sun comes out, it starts feeling like a great relief from just laying on your tube. If you’re comfortable with water and swimming, I suggest taking a

Trip Report: Sherwood Forest Faire

First Time at Sherwood Forest I have recently been introduced to the fun world of renaissance festivals, so Jack and I took a trip to the Ren Faire in McDade, Texas. Upon arrival, a group of characters were handing out flyers to gain attention for their show, which happened to be called Blunt Force Drama. Once we Jack and I finally made it through the festival gates, Blunt Force was of the first shows running. So of course, we stopped there. The show is a melee fighting tournament mixed with adult humor. The show starts by picking judges from the crowd and then the fighting begins. They even have adult humor commercials while you wait for the next round. I thoroughly enjoyed the fighting and the humor, but some might find it offensive (it was pretty racy). Also, I wouldn't take kids. Once the show finished, we followed Jack's policy of taking a lap around the grounds to see what shops and shows are available. This led me to find some awesome leather armor
