Current Projects chat and miscellany

I need to find out how long my subscription is.

my colleague at work used to laugh at my magazine, but I caught them trying to read the article on the Tour De France (about whether the bicycle really make a difference, which turn out it didn't, just our fitness levels).

Yeah I think I read that one, is that where he compares other athletes' improved performance over time with cyclists'. Its good to have an alternative voice to all the weight weenie aerodynamic chatter. There's so little proper writing about the science of bicycles.

I like Jan (the editor/chief writer) I 'know' him from a couple of lists/forums I used to use- but he's very opinionated and sometimes bends the facts/history to fit his mission/obsession.

Still because of BQ and others I ride much wider tyres than I used to, normally nothing below 28 (new Cougar is exception) and thats all good.

Do you have either of the books Golden Age or Competition Bicycle? They're lush.

Read this.

I don't know about the rest of you but Im still going to pump my tires to 120 psi

I did find him to be rather opinionated, but I did notice that his opinion did change (if slowly) over time and end up being more refine (as in narrowing down the type of bicycle suitable for all kind of riding).

I also end riding with wide tyres too, just the limitation is the frame (current max on the roadie is now 26c, previously on the old one I managed a decent 32c that was just spot on).

clearances are very tight!

cheers

Lets start a club

It's a road frame with a big ring on the inside of a road crank, there'd still be plenty of room when you use the normal small ring.

Unless you're a lard arse, that's still way too high.

nope I weigh about 10 stone. I dont have any problems with vibration and I don't want to have to pump my tyres up every day they can just slowly go down over the week. At least now I know come friday no performance has been lost.

Well, apart from the performance you lost Monday to Thursday by having your tyres too hard.

I must be going fast -this bike's really uncomfortable.

Thing about tyre pressures optimised for real road conditions is that you can be fast and comfortable (ish)

rocking 145 psi and suspension seatpost right here

nope I weigh about 10 stone.

Okay, way too high, I'm 12 stones and I ran it a lots less than that.

comfort = faster, especially on the bad road of London, this isn't the Tour De France where the road are generally quite smooth.

I weigh 67kg and for racing (TT/Tri) I ride 100/120. For training and fixed I ride 90/100 but I'm relaxed about pumping the tyres on my fixeh so normally far softer than that.

90kg (in the summer, anyway) 120psi on the TT bike (700x20 front, 700x23 rear), 90psi on everything else with 700x25s

I don't think you really need any more than 100psi for general road riding.

I pump my tyres up occasionally. That is all.

^^^ Why the mis-matched tyres on the TT... I'm pretty sure you wouldn't do that without a reason.

people pump tyres?

its not the original fork, its a cheap tange one

I retract my snarky GIF.

people pump tyres?

I like my tyres hard. Rock fucking hard.

^^^ Why the mis-matched tyres on the TT...

20 on the front because the HED3 works best that way, 23 on the back as that's the heavily loaded tyre so the lower rolling resistance of the big tyre is of more benefit, and the disc is less likely to suffer aerodynamically.

here's a little quick project I just did.

I saw reeen had used a bit of rubber + some zipties to mount his rear light under his saddle. I thought it looked neat as fuck, so I totally copied the idea. Found a bit of natty plastic tubing lying around, used a breadknife to cut a chunk off, found a couple of zipties and 20 minutes later, voila:

Pretty chuffed right now.

high tyre pressure bastards.

I run 22/19mm R/F on the fixed, and 25/23mm R/F on the road bike. As 60% of your weight is on the rear it usually needs higher PSI. Running a bigger rear, reduces the pressure needed there, and gives a bit more contact patch for drive.

Running the same size tyres front and rear. When these wheel carry different weights, and do different jobs. Seems pointless.

Thats probably MTB logic sneaking in though.
