What did you do TO / WITH / FOR your bike today!

[fjohn860]

Is there a need for more than 10 gears (11-46)?

Probably not really. My 11 speed is 11-42 so smaller big cog.

Also smaller jumps in teeth between gears so maybe easier to find the right gear...?

I rode 1x9 for years and never really wanted more. Easier climbing with 11 though.

These turned up today and with some encouragement from the forums I will have a crack at fitting them next week after the superflow race this weekend. 223 front and 203 rear - the 2.3 rotors appear soooo thick compared to the 1.8 shimanos on there at the moment

Damn cool and windy out there today but had to take the opportunity for a morning blat.

The trail gods have granted me a pair of ladies sunglasses. I don't know what they were thinking and I prefer multitools. Oh well.

Any idea how to get rid of wailing banshee sound coming from my rear brakes when I slow down? Front brake is fine.

In order of best case scenario to worst:

1. Adjust alignment of the caliper
2. They are not bedded in properly - sand the pads down a bit and go to a big hill, roll down doing hard stops but not actually coming to a stop a dozen times.
3. Contaminated pads and/or rotors - Sand pads then clean pads and rotors with isopropyl and/or or burn them on the bbq (pads facing up!)

If all of the above doesn't work then it's new bike time.

Clean the rotor with isopropyl alcohol and a clean oil-free rag or towelette for starters. Go simple first.

Other possible causes are glazed pads or rotors that have taken on too much heat at some point, fine dust surrounding caliper piston that can lead to vibrations or the caliper could be a bit off centre.

It's the new bike so likely a calliper adjustment or not bedded in yet

I did this once, worked for me.

Did you wash New Bike and they are still a little wet ?
Do the Stop Go - Accelerate , slow down , repeat .

Try the other chaps ideas first !

Mine carry on after I've washed it , but not after i go through puddles / creeks .....?

That's another point.

Keep bike wash and lubes away from the rotors and pads.

Did you wash New Bike

With car wash? Probably should be in the F-wit thread, but I took 6 months to realise my car soap wash AND wax.

Muc-off wash sorted that

 

[HamboCairns]

Good tip, I'll give it a go!

A lot of car washes have silicone in them and that's the worst shit ever on MTB brakes,

These work well...

I wash my bike with dishwashing detergent, which crosses over with another way to clean your pads. Pop them out of the calipers, dab on some detergent, add a little water, rub together and watch the filth foam out. Repeat as required until foam is clean.

I've only washed my bike with water, no products have touched my bike yet!

I have a bottle of Krush for when the time comes.

If you easily don't resolve the problem,

I'll give you a good tip, replace those cheap rotors and buy the shimano ice techs.

Would I need to use sintered pads with them or is resin OK?

I only run semi-metallics on mine but can't see why you couldn't run a harder pad other than make the disk wear out faster.

 

[HamboCairns]

I guess I'll add Ice Tech rotors to the wish list!
