In this case 50/50, very rocky trails with plenty of sharp edges, but I was probably a little offline. I've dinged two rims in 2 years so I don't think my line choice is tooooo bad. Been looking at a DD dhr2 as my current one is pretty beat up, you reckon that would help much? If not looking at rimpact or nukeproof ard

I am upgrading my brake pads to metal from resin, and as my rotors are designed for resin only I decided to upgrade my rotors to Shimano Ice-Tech, and increasing the front from 180mm to 203mm. The rotors are scheduled to show up next week, but the pads are backordered for a few more weeks.

If I install the new rotors, will anything bad happen when I make the switch from resin pads to metallic pads? Or would it just be best to keep my current ones on until I can make the whole swap. If I have to do anything special before switching pad types, I will probably just keep my current setup until the new pads arrive.

Nothing is currently wrong with my pads or rotors, I am just going to be doing some downhill park riding later this summer and don't want my brake performance to fade over long descents.

never had any issues with running metal pads on a resin pad only rotor. it'll be more prone to warping and the rotor will wear out faster.

Currently running a 1x9 w/ a sram x5 9 speed medium cage derailleur. Will an X-7 Type 2 10 speed rear derailleur work in place of the x5. Both look very similar, have 1:1 pull ration, just wondering if the extra speed would cause problems.
yes it will

When you get your new pads just sand the shot out of the rotor with Emery cloth clean it with isopropyl and then bed in the new pads and you will be fine.

get a DD. good insurance, and super meaty. probably lighter than using an insert too. they are a bitch to put on tho just a heads up.

For putting stubborn tubeless tires on and not damaging the rim tape I use Mavic tire levers. Super thin and wide.

OK, sudden brake power loss. Was fine , stopped to chat an all power gone from the brake. Lever hitting the grip, quick look couldn't see any fluid, no wet spot in the trail dust covering the bike. Inspected all hose joints, pistons lever etc.
Hope mono,moto 07
Brake is working when the pads eventually hit rotor

So weird the way it suddenly happened , any experience before I get the spanners out
Cheers

I have just cleaned my brakes with brake cleaner now I have no stopping power! What went wrong?

Exactly why I don't use brake cleaners, they always leave a film on the rotor and pads in my experience, never get them back to 100%.

Sand the rotor and blow torch the pads.

Get some wet and really gritty dirt, plaster it over your rotors, pedal down the road and do a bedding in type process, the abrasiveness grinds all the contaminant away, it sounds horrible when you are doing it but that loud grinding sound is a good sound.
