How did you do that?Mulger bill wrote:New SLX 1x11 drivetrain arrived Friday

Cut the chain a link or two short
you only have to wrap it around one chainring
and over the largest Cassette Cog , and thru the clutch Derrailleur
really , really hard to !! BAN ME NOW FOR SWEARING !! up
plus with joining quicklinks ... Even for Shitmano.....
you could have ridden it long and recut, without issues

No big deal, we've all done it. Or cut cable housing just that little bit too short, or crimped the crimp end just that little bit too much until its no longer recognizable as a crimp end. No biggie, just means you have a spare, short-ish chain floating around.Mulger bill wrote:Followed the standard procedure, ring and big cog without the mech and add a link.

For future reference, that's a crap method of chain measurement. I don't care if it's suggested by some component manufacturers, it's still a crap method. Always include the derailleur in your measuring to ensure you've got a margin for safety, especially if rear suspension is involved.Mulger bill wrote:Followed the standard procedure, ring and big cog without the mech and add a link.

i'm with this, that method may have been good when there was 2 chainrings and 5 to 9 speed casstte , with a narrow range , and road short cages , it not work on modern mountain bikes ... see linkDuck! wrote:For future reference, that's a crap method of chain measurement.

Anyway, bits swapped, new bike going, plenty of riding, and as it's summer, no need to get dynamo system going.
End of summer approaching, better get my finger out. Start hunting high and low in shed for light system, as need to get new connectors. Can't find it for love nor money. Waste 45 min, looking, looking, looking
Damn, can't find it. Maybe I threw it out by accident.
Nope Still on the old frame ....

However inevitably I was not careful when shifting once too often, and this time the chain got tangled up and in the process I managed to kink it. Ok not a big problem, it was still working well enough and I pressed on, I still had 15km to go to get to work. In fact it was working so well that I pretty much forgot I was supposed to be nursing it.
Towards the end of my commute I have a choice of two bridges to cross the railway lines near the MCG. One has a gentle slope is nice and wide but often has other foot and cyclist traffic. The other is narrow and steep and more fun. Like a fool I made my usual choice for the more fun option. Of course this meant changing to the biggest cog and in doing so I suspect the kink in the chain caused it to overshift into the spokes. Now I've managed to achieve a bent derailleur hanger, two broken spokes, on top of the kinked chain, all because I was too cheap to change the ring and chain sooner.
Cheers,
Cameron.

I waited until I got home before looking at the problem, and it took me about ten seconds to fix - without tools - by simply adjusting the cable adjuster. I don't know if I screwed it in or out, but, if it had made things worse, I would have tried the opposite way.

Whats a big Dog???Philistine wrote:I took my MTB out yesterday for a long, slow ride. The long part was planned, the slow part not so much. Early on in the ride, I tried to shift on to the big dog, and the front derailleur flatly refused to co-operate. I briefly considered the possibility of stopping to adjust it, and then I thought about the very real risk (I understand my limitations) of making it worse instead of better, and so I kept on going.

48 teeth on my MTB. Not really such a big dog - more a Collie than a Great Dane! Even so I missed being able to use it when the alternative was 38 teeth.jackthelad wrote:

I have to disagree with you about single rings. My first "good" bike (more years ago than I like to remember) had a 46 tooth chainwheel and 14,16,18,21, & 24 tooth cogs. I was happy enough with it at the time but I did not know what I was missing.

Turns out idiot me for some reason had the barrel adjuster wound out sooooooooo far that the bottom of the screw had disappeared into the caliper arm! For those that have never taken much notice of such mundane things, this is about 10-15 full turns of the adjuster
It's okay to leave it unwound a couple of turns when you first attach the brake cable for when the quick release doesn't open up quite far enough so you can cheat a little but all the way into the caliper arm ?
When I replaced the brake inner cables last year, I obviously wasn't paying attention.
I'm pleased to say that after winding in the barrel adjuster and reattaching the brake cable, the annoying knocking is now gone.

My Ay-Ups used to be used daily and as a result the plug on the end of the battery failed internally. Contact Ay-up, older batteries aren't serviceable but they have heard of people cutting the old plug off and attaching a new one. Too easy.
Trial fit new plug and there's light again. A couple of spots of solder for security and we're good to go......
Except I hadn't unplugged the battery from the light bar and I totally forgot about heat transfer through the plug. Melted at least one joint and fried who knows what else.
I went from having lights with no battery to having a battery but no lights

I wish I could afford to have put Di2 on halfway through when jiggling the cables through for the fourth time.

Was a day for bike maintenance so thought I would look at why the pump was hard to use - hmm when did I last grease the plunger? Dab of rubber grease & all is good again

I see that on my patents at work quite frequently. I also see the whole pad holder assembly fitted backwards on the odd occasion too.find_bruce wrote:Was cleaning my brakes & thought "that's not right" - I have been riding around with the brake shoes in backwards.

That’d be the one - nothing but a grub screw resisting the pad from being spat out right when you need it.Duck! wrote:I see that on my patents at work quite frequently.
