The biking thread

Um, awesome! :) I'm terrible at technical things but this should be straight forward. Well, at least moving the whole thing along the bar to the stem.



I understand the second bit, but not the first bit. :embarrassed:

Seems like my bike shop did a 🤬 job fitting the bike to me.

Check this out (http://www.sram.com/_media/pdf/avid/AVID_BrakeSetUp1.pdf)], it should explain better than I can descride. I don't think there are many bike shops they do set them up properly TBH :indiff:
 
I got a Q for the hardcore guys. Should I upgrade the pedals? I used to have baskets but I'm not sure if those are the "in" thing anymore...or if special shoes/clips are popular...or just going flat foot.

Anyway, suggestions on my first upgrades would be appreciated...as I plan to find some new peeps to ride with and I don't want to look like a poser.

I wouldn't bother with any kind of restraints, you want to be able to get out of the pedals in a hurry if you have to. I ride these on my BMX and these on my DJ, both awesomely grippy, decently light, and dirt cheap. :D
 
Anybody ever participated in an alleycat race? I know it's a bit hipster-ish but I had a great time at one earlier tonight. Yes there was Pabst Blue Ribbon and clove cigarettes but once the event starts, these guys go FAST. I spent a short time picking pieces of melted rear tire off my frame afterwards. Skid stops are the cool hipster way to stop whether you're fixed gear or not. You gotta lock up the rear tire so people see your spoke cards. These races are also an excellent way of losing fear (but not respect) of traffic. When you're going the same speed as traffic (if not faster), it's much less daunting.:sly:

This was run point-to-point, checkpoints known up front with manifests handed out a half hour prior to start. There were 11 stops, 2 of which I skipped due to poor (well, actually nonexistant) route planning on my part. I wasted my half hour planning time just BS'ing with people and drinking PBR (meh).

I covered 34.22 miles but I don't have a time for that as that isn't how these races work. I'd guess it was about 90-100 minutes. I know I wasn't the only person who skipped a checkpoint or two. I'll find out how well I did once the scores are tallied up. This put me at 804 miles for the year (or at least since May 9th, when I started tracking every mile).

No, but from the sound of them they're right up my alley. :sly:
See what I did there? :dunce:

That be true. 50kph isn't so scary down hill when the cars are doing the same and one can just occupy a space in the middle of the lane.

Shem Vs Taxi (or how Shem stopped worrying and learned to bust a knee)

Yesterday saw me arrange to meet some pals at a local theme park so we could go fishing for the afternoon. The park is around 20k from my house. Not a problem for the bike.

I took my time getting their, spent a few km warming up in low gear before setting off at a moderate pace. I arrived within an hour and we set about making our afternoon plans.

Fishing went out the window when we found a bar with cheap Jim Bean. My friends had plenty., I had one. :(

Many drinks later we decided that if we go back to our town we can have some dinner together and I could have a beer because I wouldn't be riding. I made a sly remark that I'd keep the beers cool for them once I'd reached town. They laughed. Challenge on.

Their weapon of choice only available transport was a taxi, a bus was just too slow. I had my trusty push iron and a set of lungs. They had to contend with traffic while I didn't and I knew the fastest route, the taxi drivers here are complete retards.

I left the park and them, waiting for a taxi with more speed than I should have and made my way across the city. By this time people were coming home from work and the traffic was starting to build up. A problem for them not me. I was going at full pace the whole trip apart from the last 1.5km which are up a ridiculously steep hill. I took that hill rather slowly having used much of my power on the previous hills.

I arrive in the town centre and my friends were there waiting for me. I was a bit gutted until they told me they had just that minute got out of the taxi.

Feely rather chuffed with myself for matching the time of a car over 20km I dismounted to discover that my right knee would no longer take my weight and had obviously been damaged from over exertion.

Today I'll rest it and hope it gets better. I had the same problem last month with the same knee. It should be fine in a few days but right now I'm relegated to the sofa. Time to get my GT on.

Great footage!


I've got a quick question about tire pressure, how do I know it is set right? I think I'm running about 45 psi which is on the low side of the tire restrictions (35-65) but not the lowest it can go. I don't want to pinch the tube, but since its a hardtail i also don't want to sacrifice comfort and/or grip.

Just curious what you guys run. I guess your weight plays a part too... I'm about 195 lbs.
 
I think the most important info for choosing the correct pressure would be what kind of riding you are doing and what kind of tires. If you're on roads or other hard surfaces you would probably want to keep the pressure at the high end of the range. Use the lower end for looser surfaces and muddy conditions.

Some of the other guys around here could probably give some better input if you are on a mountain bike.
 
ahh yes...of course. well since i'm mountain biking, roads are out of the question. the type of terrain i'm on is double-track fire roads (somewhat rocky) and windy single track that is a mix of packed dirt, roots, medium sized granite rocks, and the occasional muddy section. Most of the mud can be avoided by staying on the narrow bridges.

I'm having trouble mostly with short but steep hill climbs on rolling terrain. Part of it is me being out of practice and not finding the right gear quick enough...but occasionally i'm slipping the rear tire while climbing.

I'm also having a bit of trouble getting used to the new bike frame. It's a Gary Fisher Wahoo with their "G2" geometry. I didn't think it would be as dramatic but it definitely feels different. On some bikes I can ride down a flat paved road and carve out esses with no hands on the bars. I can't do that with this bike...or at least I'm afraid too. I'm not even confident removing both hands in a straight line. Like a car with bad ball joints, the G2 geometry is very loose feeling at speed. However, at slow speed, I see its advantage. Another quick test is doing figure 8s in my garage around two metal poles. i can carve tighter radius turns and the input required to go from 0-10 degrees is the same that is required to go from 10-20 degrees. Other bikes require more force the tighter radius you try to make. I suppose Gary Fisher's thinking is that this is good for weaving quickly between rocks at slow speed...once i get used to it...but right now i'm having trouble learning the limits of the front tire's grip and therefore find myself understeering through fast sweeping turns and just plowing over rocks in my way instead of weaving around them.
 
In summer(dry, dusty trails) I usually have my tyres pumped around 40psi, in winter when things get a bit muddy that drops closer to 27psi. On my DJ bike I run 60-70psi for maximum speed at any time of the year because corner grip isn't as important in that discipline.
 
There is no definitive answer to what tyre pressure you should be running although a lot depends on the width of your tyres and the width of your ass. Have a look at this FAQ, particularly the second post > http://www.bikeradar.com/mtb/forums/viewtopic.php?t=12674161

I run mine quite high although I'll be letting some out the next time I go to a trail centre. If your rear tyre is losing traction on steep climbs move your body weight for extra grip, always aim to have your belly button directly above your bottom bracket for ideal weight distribution whether you're going up or down.
 
I run the recommended pressure of 100psi. I only weight in at 60kg/ 132 pounds (Aero-Shem :lol:). They're skinny little things so even with a little bit of deflation I can really feel the extra power needed to do high speeds.

I've considered my old mountain bike tyres for winter but have decided I'll only not ride if it's raining and leave the slicks on. It's forecast rain for today but it's 6:45am now and only foggy. Shall I risk it? Na.

Yep, same here at 145 pounds. There is a noticeable difference between 90 and 110 psi. (I'm road only, no mountain bike)

You can try and do specific leg exercises to improve the strength of the leg and prevent it from getting damaged (badly) again. Squats, wobble board exercises, lunges, quad and hamstring raises (or weights machine), hip flexor stretching/strengthening should all be useful to prevent it from getting injured.

With regards to chuyler1 question on tyre pressure, I am on a road bike so the pressures I use is between 80 to 100 psi. I do notice it when it is less than 80 psi as you start to get a bit of a bounce going and that's MEGA annoying, especially when you're sprinting uphill or just caning it on the flat.

This is my bike, for those who are wondering what it is

It works nicely, although the gears may need replacing eventually. It is a 21 speed, which isn't common for a road bike but it does make it a lot easier to go up the hills with the amount of gears it has if you are on a challenging climb. The tyres are pretty skinny and this leads onto my greatest fear. Wet roads. They do have some tread of them, but because they're so thin I am not at all keen to actually ride quickly on wet roads if I have to turn or lean. I don't like falling off.... and my balance isn't the greatest!
 
I'll take note of that, thanks Submerged. I can't see the pic of your bike on my office PC for some reason but I'll check it out later when I'm using a different computer.

I use the skinny tyres myself and mine have hardly any tread. I've decided not to ride in heavy rain due to the obvious consequences.
 
What would you guys recommend for me if I were to get a bike to make traveling around campus a little quicker/easier? I'm 280 pounds, 6'3-6'4, and I need to carry a messenger bag. What would be even more awesome is if I could carry a giant Boston bag with all my kendo crap in it (20 lbs; heavier when sweat-soaked after practice). Here's a pic for reference, except I'm a big guy with big armor so my bag is like filled to capacity. Do they make racks that can hold that crap?

What's the best I can do for the cheapest price? Mountain bike? Hybrid? What do you guys think of those bikes with shaft- or belt-drive instead of chain-drive?
 
For traveling around campus, check on craigslist for a hybrid. You don't want nubby tires, but you don't need a road racing bike. Since you'll be parking it outside school buildings, you don't want anything fancy that could get stolen. Tires should have some tread pattern to provide you grip in the rain. I bet you could find something for under $100. I'd stay clear of the single speed stuff. At 280 with another 20-30 lbs of gear you'll want something with at least 18 gears so you can manage hilly terrain. They also sell racks you can put on the back. With a few bungie cords you could probably strap your gear to one.

The only thing on craigslist with a big enough frame is some 900 dollar cannondales and other road racers. I'm sure they have a bunch up for sale between semesters or after graduation, etc.
 
i could ride a men's small/medium frame if i had to. it's not ideal for trail riding but back and forth to class it would be fine. Where are you located? I'll skim your local craigslist for something.
 
Get a fixie, you've already begun your hipster look with the messenger bag. You'll only be riding it around campus, hipster points for doing that too.
 
Take it that Imageshack doesn't work at all in the office?

Doesn't work in the office, works at home. Must say that that bike is more what I've been working towards by modifiying my bike. You lucky so and so, I can only dream of a bike like that for the next year. :sausages:

A tank. Plenty of space for a messenger bag.
 
I just went for a XC mountain bike ride on my lunch break. It rained all yesterday but the sun came out this morning... We're supposed to get more rain this weekend so I wanted to get a ride in.

The moderate climbs were fine...the downhills were a little frightening when things got rooty, but worst of all were the plank bridges. Still damp and covered with leaves, I did fine if I had a straight approach. That helped me build up false confidence. The 3rd bridge on the trail is about 40 ft long and forms a curve. I hopped onto it no problem carrying some speed from a downhill section, but at the first seam when I had to lean right, the back tire slipped right off like I was on glare ice. I felt it coming, luckily, and had my right foot off the pedal. Somehow I managed to dump the bike and hop over it without catching a handlebar in the crotch.

Lesson learned...take bridges slow when they are wet :)

First time I went mountain biking back in the spring I took a demo from the local shop and dumped it on one of those little bridges because of the rain the night before. All the crazy stuff I made it through that day and I dumped it on a flat, straight bridge. It was near the end of the bridge so by the time I hit the ground my knee hit the dirt/mud/rocks and now I have a huge scar on my right knee.
 
There's no other way to say this, I almost died yesterday. Ok, not really, but it felt like it. :lol: I was standing up pedaling my DJ down the street, which is a mountain bike with a DIY singlespeed conversion (just one cog slipped onto the splines where a cassette would go, held in place by rubber tubing on each side to get the spacing right.) Slightly ghetto, but it has held up great so far, until the chain slipped off while pumping at full strength at full speed. :scared: Both feet flew off the pedals and I knocked my seat out of place with my crotch, and then almost swerved into an oncoming car. My next project as of now is going to be finding an old derailleur that I can turn into a chain tentioner.

Homegrown parts FTW!
 
I figured it would be a temporary thing too, but so far it has held tight for almost six months now. But yeah, I need a new plan after what happened. I would use old cassette spacers if I had them, but I don't so...... to the garage! :lol:

Edit: You should have seen what was on there when I got the bike, the cog was pushed all the way to the spokes being held on by the remains of a sprinkler head. :lol::lol:
