no.

matthew glaetzer kept racing his bike after this.

Thankfully I didn't go down, I just got jammed in the doorway. Thanks for the reply guys. Glaetzer went down hard!

You should be fine.

1) You can take a coin and tap around the area you suspect is damaged and listen for a dud sound.

2) Even if there is a weak spot, it's probably fine.

3) Carbon forks have metal blades in the middle.

Not any of the ones that I've had or broken. Aluminum dropouts, crown, and steerer, but all the blades have been straight carbon. Kinesis used to make carbon wrapped aluminum fork, but that was ages ago.

Good.

Also, a key component to making rollers work best is making sure that they are adjusted to the right length according to your bike. Too long or too short can have wonky outcomes.

I sure wish someone had a video of my crash at Master's Natz in Rock Hill. I'm told it was spectacular, but I don't remember any of it. Back on track (pun intended), the only thing damaged on my bike was some carbon was ground off the top of my Scatto's, and my left aluminum pedal took a beating. My body and head, however, were not treated as well by Giordana's concrete.

I have fallen off the rollers in the manner you describe, and I doubt any damage was done to your fork. I like the "hit it with a coin" method of testing already suggested. Bouncing wheel and fork off the floor and listening for weird sounds also works as well as anything. That's how I found I had cracked the carbon handlebars of my road bike.

I bought a set of Tacx Antares second hand off craigslist. At their max length, the front axle is directly over the front drum.

That sounds like a good setup.

I like mine with the front bike axle directly above the front roller axle or with the bike axle no more than 1cm behind the roller axle. If you go forward of the roller axle, you may hop off the rollers forward. If you are too far back from the roller axle then handling gets wonky.

There are lots of tutorials on how to ride rollers. You'll get it...or you'll destroy your home trying

This in my opinion is the optimal way to set up rollers. It allows you to really rev out and still holds you back in the rollers a bit. You should also check to make sure that they rollers are set up level, front/back, side/side. Most floors are hardly level (especially in basements where they are graded to facilitate drainiage).

Hey I am 16 and just got a road bike a week ago, how fast should I average, I know speed is not the most important thing but I don't have a bike computer to measure my cadence. So what is a good average speed for me

Does anyone know any track related youtube channel?
I know GCN, Bikeradar, and etc, but they hardly talk about track cycling.

Hi, Spencer99. Welcome to Bikeforums.

I believe you posted in the wrong forum. This forum is for Track Cycling training and racing. You should post Road cycling questions in the Road Cycling Forum.

Good luck!

Youtube has lots of video - just enter bicycle track velodrome in the search box.

If you are looking for live coverage I've found the race web site sometimes has broadcast or streaming info. I watched every minute of the PanAm games and each hour record attempt this year.

Aero wheels - what variables contribute to choosing which type of aero wheel for which event? Eg, sprinters using a five spoke at the front and disc at the rear opposed to two full discs in a TT. Surely you'd want to be as aerodynamic as possible in all events so would choose a double disc set up no matter what, unless maybe a five spoke is stiffer to suit sprinting more?

front discs are only allowed in time trials.

so, basically, front disc for time trials, five spoke for everything else. that's at the highest levels, of course.

below the highest levels of the sport, it's more of a "what i got" situation. i have a 60mm wheelset and a rear disc. i tend to use the rear spoked wheel for points races and miss and outs - on the idea that it would 'spin up quicker' or some negligibly-tangible benefit like that. the faster and harder the race, the more i'd want the disc. seriously though, i doubt i felt a difference - i just had the option and went with where i knew there'd be a (theoretical) benefit.

i know plenty of people who are competitive on the national level who just use a 60 or 90mm setup. and plenty who just have a disc - any old disc, even literally a twenty-year-old disc sometimes - and a 60-90mm front wheel.

What particular reasons are there for front discs to only be allowed in time trials then? I wouldn't have imagined there to be much of a safety issue in it, but then again I'm the one needing to ask this question in the first place!

Front discs and really deep front wheels can be unstable, even for the strongest of riders.

Imagine going 40+ MPH / 65+ KPH and having someone tug on your handlebars... That's what it feels like when wind catches a deep dish wheel.

Smaller riders are affected more than larger riders. All are affected.

5 spokes have proven to be a nice compromise between aero and control for riders of all sizes. Mavic got it right with the Io.

I've never ridden a front disc, but I have ridden Zipp 404, 808, and 1080 up front and they are all very different. 808 is as deep as I would like to go.

Anecdotal story:

2012 Masters Track Nationals in Colorado Springs. A crew from ATL was present. As with all crews when traveling to race, all equipment is "community equipment" (for the most part). If you need it, you are welcome to use it. In the camp we had a custom zipp 1080 front wheel with a track hub.

(This isn't it, but looks like this)



This is about has close to a front disc you can get without getting a front disc.

Very experienced 60+ masters guy was gonna do his 500M TT. He unusually uses a 404 type front wheel. No one was using the 1080. He's like, "What the hell...why not? Deeper is better for TTs, right?" He'd never ridden it before.

He gets called to the starting line. 5...4...3...2...1...0! He goes off with a strong start. Gets into turn 1 and waves up track and lets off the gas (???). He recovers and finishes the TT. Didn't do as well as he'd hoped.

He says the wind caught the wheel and, "Stood me STRAIGHT UP! STRAIGHT UP, Carleton!"

I don't think he ever used that wheel again.
