Road Cycling

I use a speed and cadence sensor built into the bike now but even before that the Garmin average speed always got trimmed back by Strava. Track session last night my Garmin lost the first 50 minutes of the session - we're not allowed Garmins on view so I shoved it into my jersey pocket - got it out 50 mins into the session and it had switched off for some completely random reason - GRRRR. Switched it back on just in time for an end of session 36 lap race so at least I got that recorded.
 
so likely a result of auto pause.

Strava doesnt do auto pause otherwise you'd be able to have a rest halfway up a climb and still get the KOM. It does ignore the times when you're stopped for calculating average speed though.

So all the time you're speed is between 0-3mph is included in the strava calculation but ignored by garmin. That's why strava will give a more accurate lower average.
 
Feeling under the weather today. Everyone in our house seems to have this sore throat/ feel like ****. I just couldn't get any power out this morning, it was a killer.

Nice days out though. Sun shining, 30c. Means I can potter to and from work trying not to die.
 
Guys, help me before I lose my rag with my bike and go and buy a nice new one :p

Went out Sunday and after a mile or so noticed an annoying noise that at first sounded like stones pinging off the front of the frame, but I quickly realised it wasn't that. I've no idea how to explain it really as nothing really reproduces it consistently other than going over rough road surfaces, that always seems to to make it happen.

I began to think it was when I was putting my weight on the bars as it seemed to happen less when I was sitting upright and had my hand on the tops. But as the ride continued I realised it wasn't that simple and it still happened when I was doing that too. I kept stopping and checking as I thought I figured it out, thought it might be the cables hitting the frame, or a loose spoke, or something in the brakes. But every time I thought I'd nailed it, nope it came right back.

By the end of the ride and 30 miles of listening to it, it sounded like it was something inside the frame, forks or bars. But then Ben suggested it could be something inside the tyre or the hub

Any suggestions as it's driving me mad. I swear my average heart rate would have been 10bpm lower that Sunday ride if that noise wasn't winding me up
 
A loose value nut on your inner tube banging against the rim. Strange noise but once you've had it once you'll always do your value nuts up a little tighter (or remove them completely. I keep mine on, just done up nice and tight against my rims!).

Check spoke tension, a loose nipple can cause the spoke to bang against the rim, the spokes around it will start to loosen too and before long you'll have a rim stuck against your brake caliper/fork/chainstay. If you've had a 'broken spoke' (more commonly a broken nipple) some of the debris left in the rim will rattle around.

Front derailleur cable end catching the pedal arm once per revolution, or vibrating against a frame/mudguard is quite an easy one to miss/spot/suddenly suffer from. I tend to have that cable end quite short for this reason (and once when I lost a cable end, the frayed end of cable ripped a hole in some bib tights. Expensive mistake for not replacing a ~5p endcap!). I don't have a problem with short derailleur cables as they stretch with age, not shrink!

Chainring bolts. Check they're tight. Although they tend to creak/groan if loose, if there's dirt in between two tight surfaces when pressure is applied (a gap which normally isn't there - like chainrings & spider) it can sound like a click.

Those are the easy things to spot/diagnose/suffer from. There's probably many others too (before you start looking at things like bottom brackets, derailleur alignment and stem/bars)! ;)
 
I'm going to get the tyre off tonight and check that! I'm confident it might be that! It definitely sounds like it's coming from the wheel/forks. Thanks Roady

It's probably about time I finally took the tyre off anyway and practised changing an inner tube. Still not done it and it terrifies me every time I go out :p You'll read a story about a cyclist that died at the side of the road after getting a flat tyre and just gave up, 4 miles from home

Crawling up to the lights to avoid having to unclip is the worst, that kills your average. Better to race up to the lights and stop on a dime :D
 
Has anyone ever opened a freewheel with a pin spanner? It seems like pretty hard work. I don't have a vice, but I think I'm going to need one.

My halo clickster is gunked up and given it cost £30odd I'd like to have a stab at servicing it. It's that or I just bin it and keep buying £10 piece of crap ones and chucking them every time. That or I spend £90 or something stupid on a white industries one with cartridge bearings.
 
How long/how many miles did it take to get gunked up?

Personally, I consider freewheels consumables but if you haven't had it long before it packed in I'd be pretty disappointed! I fitted a Halo Clickster this Feb after using the cheapo BMX ones up to now so I hope it at least outlasts one of those.

Yes - sorry I meant the Garmin auto pause is likely meaning Garmin pauses while Strava is still recording hence a faster speed there :)

It's been on since November, but it's probably done a couple of thousand miles or so in all conditions, maybe more, as it's on my commuter.
 
So I've ruled out wheel/tyre for that noise :(

Here's a video. I'm pushing down and then as I ease pressure and roll back or forward you can hear the click/cracking sound

Any ideas guys? :(

There's lots of little bearings in there and it's pretty easy for them to go everywhere.

As I recall the part you open will probably be a left hand thread

is the fork's steerer tube rocking/lose in the frame - weight/force through the handlebars will cause it to bang forwards and back?

retighten the headset (making sure to undo the bolts on the stem 1st) - does that help? Could do with a complete strip down, clean and re-grease?

where do you perceive the noise as coming from? 90% of all bike noises sound like they're coming from the BB area, even if it's actually something else?

I've often come across handlebar/stem interfaces that tick a bit like that, usually when you're honking on them though
 
It sounds and feels like it's coming from the stem or handlebars now I've been playing around with it off the bike and don't have other vibrations coming through the bike
 
i'd suggest that it's either the handlebar/stem interface, in which case, opening it up and popping a light skim of grease on the contact points and threads can help

that or the shifter flexing slightly against the bar, nipping the retaining bolt might solve that. (actually, this would only occur under load, so forget it)

if it were at the headset end, it'd be noticeably "knocky" or loose rather than "ticky"

if it's a 4 bolt stem which it looks like, don't forget to use the right tightening order, like this

and make sure the top and bottom are tightened so the gaps are similar
 
So it seems that the theme on this evening's commute home was if anyone could successfully knock me off my bike. After a massive highway maintenance trying to pass me stupidly close this morning (I moved into the middle of the road so he had no space in the end). I really wasn't in the mood for it this evening. One lady thought it would be a good idea to turn left without indicating and was about 3/4 inches away from hitting me, tapped on her window a couple of times and told her to give me some bloody space!!!!

Two days off work now though so glad I can avoid commuting until Friday!
 
On my short ride tonight I had an evoque cut across me pretty close and a woman overtaking me 50 yards away from a roundabout when I'm 30mph+. Went round the roundabout to her nearside to make a point and that is when she turned off, not sure where people are in such a hurry to get to!
 
Good turbo session last night, really warm & humid though, I should probably have gone out on the road! Was a little late by the time I got started so didn't finish up until gone 9.30. Her indoors was actually ok with a late 'finish' as I'd done some DIY jobs just before dinner. Much easier to get away with things on the turbo as I'm 'only in the garage' (so she doesn't worry)! Dat humidity though, I'm glad I don't have any hair to go frizzy... Not sure how FT manages! ;)

It's probably about time I finally took the tyre off anyway and practised changing an inner tube. Still not done it and it terrifies me every time I go out :p You'll read a story about a cyclist that died at the side of the road after getting a flat tyre and just gave up, 4 miles from home
You wouldn't be the first, or the last! It's a useful technique/skill to at least practice in the comfort of your own home/garage (with google & YouTube on hand).

No need to fear it, it happens to us all at some point!

Von & FT have had their fair share this year already if Strava ride names are anything to go by... It's been months since I had one (jinxed now!) :D

Better to race up to the lights and stop on a dime :D
Video please! ;)

Not sure why you'd need a vice if your freewheel opens with a lockring pin/peg spanner? I've not needed a vice for all of the hub fiddling I've done so far but I did cobble together the park tool axle vise/grip with a G-clamp to hold an axle at one point... I need a proper workbench and vise for my garage! :o

The next queue of course & don't you DARE hold them up! :D :p
