Road Cycling

That cable is really just more flexible than a standard cable to allow you to pivot it easier.

Also needed for bikes with really short cables at the rear mech as is the new trend.

New bikes with disc brakes make it awkward to get a wheel out so the cable being more flexible helps aid wheel removal.

That makes sense. Shouldn't be too much of an issue for me then.
 
That's quite interesting. So rear wear is a lot more than front? Should I be rotating tyres at 1,000 miles or something?
Do you really want a worn/squared off tyre on the front?

I don't rotate them. I tend to just have a fair stock of tyres (though that needs topping up now - GP4000SIIs have become pretty rare to find).
 
Nice morning for it, bit damp first thing but dried up as the wind picked up.

I didn’t do too much, just under 3 hrs but it was an enjoyable ride.

FSA Powerbox worked perfect, connected to my phone, updated on the P2M app, connected straight up to Garmin, faultless. Shifting no issues as I know historically the FSA rings have had a poorer reputation.
 
Just came back from a ride with the wife, got off the bike and almost immediately my front tyre exploded!

Pretty sure I didn't have too much pressure in - frightening thinking that could've happened when I was hitting 50 km/h on the last descent...
 
Got closer to my first KOM this morning, with a 4th place (3,000+ have ridden it), but wont bother posting, as it was a pretty big descent, so I'm sure it doesn't count :p Still very happy with it though. I wont lie, this one more than the other descent I have a top 10, did feel a little dangerous. Built up area near Golders Green with shorter sight than you would like at times, doing 40mph. It was nice and early though, so relatively quiet.
 
Smasssssshhhhhed the 4th cat crit today.

Small bunch but I'll take it. Sat with them for 3 laps or so.

Attacked on the tailwind section and then eased up and recovered into the wind as they chased to catch me only to go again 10 seconds later.

Launched my sprint out the back corner uphill into a headwind but held nearly 30mph for the win. Had to avoid a guy who had been dropped who decided to zig zag at the finish line.


3/4 cat race was even faster and I was writing cheques my legs couldn't cash. Bigger bunch meant fighting for position constantly. Moving up position on the tailwind section and having to go shoulder to shoulder to keep it and then out of saddle sprints into the wind to just stay in position. Was on the front a few times but ended up settling in the bunch on the last two laps as I was gassed.

Listen to yourself. :/
 
Agreed. I wouldn't say it was ever that dangerous. There's always some danger riding in London, maybe I should just stop riding completely?

There's risks we accept and there's racing through a built up area in pursuit of a meaningless online badge. I love riding fast but perhaps we have to agree to disagree on this one.
 
Failed totally to get any riding in this weekend, but at least the DIY/Decorating is 99% done. Felt good to get our house back to normal after the 3rd week of living in & around a bombsite. 7 hours yesterday of painting, stepladders and crouching I actually think I racked up a similar TSS but no way to measure it! Or does that count as a 'recovery' weekend!? :D

Just closing some tabs I had open from this morning and I discover the funny metal ferrule end on the RD loop I had is a special part - OT-RS900. https://www.bike-components.de/en/Shimano/OT-RS900-Shifter-Cable-Housing-1-Pack-p71134/

I guess that lasted less than a year with all the rain etc. I don't recall ever seeing the two other parts with the R7000 derailleur though. It seems to function fine without this special cable.
Good find. I'm not sure what the bottom bit is, mable like a barb that goes in the middle bit? I have a middle bit on my RD, fairly sure it came with it as I won't have bought one seperately. It fits and looks like some kinda cover to aid with keeping dirt/water off the cable from working it's way back into the outer where it enters the RD. Although when I fitted mine as I ran a complete Outer through the frame I didn't have the metal ferrule on the end and nothing special about my outer (standard jagwire). No gear issues but isn't a tight/small loop on the end.

I got an email from mywindsock with an analysis of my commute, out of the blue actually as I don't pay for it/subscribe. Trying to tempt me with stats, they must know I love a stat or two :p
Ahh nice. I've used it before and never had an email from them! :rolleyes:

Interesting! I'd seen the metal end bits and how they where smaller than the black plastic ones, but hadn't realised the outter itself was any different!

for academic interest i cut up a couple of prime armour tyres that i'd taken off
Really interesting to see with those cross sections, but what a waste of barely half worn tyres lol ;)

Good to hear it's gone well! :D

Damn, blew off the rim? Worth checking your rims if rime brake and you braked lots on the descents... You might've cooked it?!

Good job buddy, a mostly successful trip south of the wall then?! :D

Yeah blew a section of tyre off the rim. It's disc brake so not that, I have no idea how it happened but I'm slowing down next time I go out! Could have been a faulty tube?!

Just to balance things...

I'll actually go out on a limb and say fair play Andy. I've hunted down the segment you're talking about and scouted sections of it on Google maps rather than the knee jerk reaction you've seen from others seeing that info/data. I did that mostly as I know how when quite new to cycling how 'important' some riders feel targetting things like segments are, competition is quite key for some and I don't feel discouraging you from so much of that is totally the right thing. It's an impressive time, must have been good fun to get a fairly good clear run down that road - you don't get many like that around London, can't judge just how enjoyable that must have been! But similarly not knowing the area also can't say much about the risk. Those speeds/data will always make things look 'worse' than they probably where - the earlier part of that segment if you're going to go for a downhill segment does look an 'ok' place to do it - good visibility, good road and very little junctions or joining traffic etc as you where hitting it soon after 8am so probably quiet. :cool:

But the flip side to that - I would say the segment should really be flagged as unsafe, a safer version would be cropped to make it shorter as the latter part there's parked cars and risk of pedestrians stepping out on you. A shorter segment would give people aiming at it a more level playing field and those who don't want to risk riding those speeds in a dangerous area/slowed by traffic into it, also have something to aim for. I would also hazard a guess that you where breaking the speed limit there? I doubt it's not a 30mph zone? But that's a different argument and something you yourself will have to decide - judging the risk if a Strava KOM is really that important to you - cyclists are not immune to traffic laws, if anything I personally feel it's more important we follow them than even other road users. #adulting :D

Could have been faulty tube or even just a stone of some kind causing the bead to pop off. Very scary as it makes quite a noise!

One option is to avoid tubes and high pressures by running wide tyres/rims, this isn't the 90's ;)

I run 28mm tyres at around 90-100 psi - I'm 110kg so thought it was at that psi. What would you suggest?
 
That's a little high for 28's. Although depends on the tyre - what's the recommended on the tyre sidewall? You'll probably find you've got them at or near the maximum.

I'm running 32mm's at 40 front and 50 PSI rear but that's tubeless and I generally prefer the comfort. When running 28's with tubes I don't think I went over 60 or 70psi, but again that was riding with comfort in mind. That was on gp4000sii's and they where very soft if I ran them much lower, needed regular topping up. Really don't rate them as a 28mm comfort tyre if after lower pressures. I'm hoping the GP5000 TL are much better.

Although I do run lower pressures than most people, I'm not lightweight at 75-70kg.

Way too high. Go down to 80 and see how it feels.

Silca do a calculator and there is a really good graph online with tyre size/weight, can’t remember whose but I’ve posted it before.

Thanks, always appreciate a little balance. :)

A shorter segment would give people aiming at it a more level playing field and those who don't want to risk riding those speeds in a dangerous area/slowed by traffic into it, also have something to aim for.

Honestly, I couldn't tell you were the segment started or ended... I wasn't 'segment hunting' for that specific segment, but I do tend to try and ride full out, most of the time and will then review after to see what I've done.

The 'dangerous' bit you linked too isn't what I was concerned about either tbh. At that point I had pretty good visibility of things, I think I was even up out of the drops by then so had a higher vantage point, nice wide bit of road of which I was literally in the middle of. No pedestrians to be seen, certainly no traffic through my whole descent. It was a little higher up, there's a bend where you can't see as far ahead as I would like. (I would throw in, I'm not a risk taker. I've ridden high power motorbikes for 10+ years and have never even got my knee down. I'm often slower than others through bends as I just don't take risks. I'm always expecting the worse, like a patch of mud or ice. A nice straight bit, yes, I'll blast it if I decide it looks safe to do so though)
