Are there any training or certification courses for Derny Drivers in the US? I've emailed both USA Cycling and USA Derny, but haven't heard back from either one. British Cycling has a course, I was wondering if there was anything equivalent here in the US.

I've never heard of such, but it would be a nice thing.

Does anyone have experience using an older wired road SRM on the track? I have one I picked up recently in a trade with a friend. I've seen a few forum posts elsewhere with some saying it works and others saying it doesn't, including Andy Coggan saying that it can be done. Just wondering if anyone here has tried it.

I also have the ability to machine a 144bcd adapter plate for it, so chainline and chainring compatability won't be an issue.

carleton

I've seen it done.

I think the biggest thing is to get your adapter system right. I recall there used to be one or two people who would sell adapters to mate with Quark and other PMs for use on the track. So, you might be better off buying one and having it by the end of the week as opposed to creating one from scratch.

Or you could probably buy a set of 130bcd chainrings and be done with it, provided that you get your chainline right. That might be easiest if you are the type to only use 3 or 4 chainrings.

I guess you have options.

One thing to consider now is the battery in the head unit. They are not user-replaceable. Meaning, that you have to mail it off to SRM in Colorado to be replaced. So, if you need that replaced, do it now while you work on the bigger solution with the chainrings/adapter. It's possible to have a shop like Batteries Plus replace it, but I've never done it. So I wouldn't know what to tell you to tell them. I sent mine back to SRM (I had 2 wired SRM Track Powercontrol V long ago).

Which type? Pro with SRM arms or Dura ace etc? Heard the older Pro model is usually okay. As you already now have it, why not fit it using an existing chainring and look at the data before either making an adapter (adapters are 110 BCD and the Pro is 130 BCD so won't work?) or buying 130 BCD track chainrings.

Pro with srm octalink arms.

A 110-144bcd adapter plate will work with any chainring but 130-144 will work with chainrings that have defined "arms" like dura-ace or campy since the holes are offset.

Dalai

Thanks for the correction. Interested hear how the Pro goes fixed, as I picked up an Amateur for cheap to go on the fixed gear commuter. Though if it doesn't work will just run it single speed...

I got it going and tested it out on the track Sunday with a 130bcd track chainring. Data looked okay considering it was set to 9s recording. I've changed it to 0.5s for next time since data storage isn't really a concern. At 0.5s you can still get 3hr of riding on there.

The chainline is off though. I spaced my cog out as much as I could while still being able to fit a lockring and its okay but not great. Chainring I have is a 50t which is super useful for me so I'll just keep it as is for bit until I figure out if I want to keep going with power on my track bike.

Following up, the topeak adapter is nice but vittoria tubulars are all smooth valves and the couple of threads at the top aren't enough to get a solid hold. I came across a Hirame adapter and it works better than the crack pipe because it frees up a hand, but its a tight fit in the hole so there's likely some discs that wouldn't work.

Looking for recommendations on a chain tensioner.

I think the MKS tensioners for 10mm dropouts (assuming you're on alu or carbon) work really well - you use a 3mm allen wrench to tighten.

carleton

Those are very well-made...and time-consuming to use in practice.

Also, they come in two widths: narrow for old-school steel type dropouts and wide for newer dropouts that are thicker. But, even the wide model may not fit.

Voodoo76

I've seen the wider version listed as 8mm dropout width vs 5mm for the narrow. Need to measure to see if that's adequate.

I'm not looking foreword to the added PITA. This is more mental than some massive power driven need. I pulled a wheel recently doing standing starts and apparently that's frequent enough to get stuck in my weak minded head

TDinBristol

Voodoo - right you are - the MKS are for 10mm axles and 8mm wide dropouts. Apologies.

Question here: Does anyone make track cranksets (144bcd) that are shorter than 165mm? I see some BMX / fixie type, but a quick look comes up pretty empty.

Godsight

Ridea make crank in 155 and 160mm length is the only crank I could find with <165mm option

Baby Puke

I believe Rotor will make them pretty small, down to 135mm I heard??

brawlo

There is a road Gebhardt 150mm crankset for sale over here ATM and I have seen a track 177.5mm (edit:the pricelist I was looking at didn't list these, but the site itself does) crankset from them too. My point is that both those sizes are outside those listed on their website, so presumably they can and will make special order sizes

I am planning to get a membership from 'barbell brigade'(check their youtube channel). I think this is the perfect gym for me because it's open 24/7(i usually sleep at 2am because of the projects....) and it's only 2.2 miles away from my apartment and school.

So I am talking about the gym because i want to find a coach their(he or she might be a weightlifter and other). If he or she ask me what I want, what should I tell he or she about track cycling?
Or should I just show few pictures of Chris Hoy, Shane Perkins, and other track sprinters?

VanceMac

I know a few people who lift there, including at least one trackie from VSC. You are lucky to have such a well-equipped gym so close to you.

As for coach/programming... I would suggest really spending some time finding one that matches your goals/priorities (which assumes, of course, that you already know what those are). Is cycling your priority, or general strength/fitness? If cycling... track cycling? If track cycling... sprint or enduro? Not that there is a huge difference, but if you are going to the trouble and expense of hiring a coach, you might as well get one that best aligns with your goals.

gycho77

Oh sorry for not explaining what I want.
I thought most of the member knew about me.
I want to focus on sprinting. I don't care about how I look hahaha
So if you know any couch who could help me, I would love to talk to him or her.
If he or she is a great coach, I will pay what they want

Thanks

carleton

At the gym, just focus on a strength building program like Starting Strength or Stronglifts 5x5...basically focus on progressing your squat and others.

You are in the beginning stages of lifting. You won't need a specialized program for track sprinting. You just need to lift 3x per week and ride 2 of the other days and have 2 days off to rest, recover, and study more.

Poppit

I'd have a think about explosive strength as well so not just focussing on the actual weight but also the speed of moving the weight.

queerpunk

I made a picture about getting better at things. It applies to cycling.

As a beginner, you can make great progress without putting in much time and effort - just by:
1. Reading some basic materials
2. Following simple programming
3. Going harder than you did during your last hard workout

While a coach can help accelerate this process, a coach's real value is AFTER somebody passes through these beginner and intermediary phases, and hits a point where their improvement slows down a LOT (or stops happening). Basically, a coach is important on the blue line. When time and effort doesn't pay off in gains, and you need to be a lot smarter about how to use time and effort to improve.
