Any recommendations for lights for MTBing at the cheaper end of the scale?

[Bubba]

if a bike has cable disks, is it possible to upgrade to hydraulics?

Yes, if the bike has the appropriate caliper mounting points on the frame.

ive got £300 or less to spend on a full sus mtb. any ideas apart from the deacathlon rockrider 6.3?

That bike has good reviews: See here.

I'd be interested in that too - any recs anyone?

I got these, pretty good for the price, but think I got the last of the stock on sale.

Pretty dear at full price elswhere, might be worth shopping around.

and hubs on the wheels that you can attach a disc to.

[Bubba]

If it's got cable discs then it'll already have those

And it'll already have the caliper mounting points!

Ah well - i read it as old style cable brakes.

So, in answer to the original question: yes, but you'll need new calipers, levers & hydraulic brake lines.

If he has cable disc brakes already then he must have hubs that allow rotors to be attached......

Worth looking at Merlin Cycles website for some good deals on disc brakes if you decide to upgrade.

Anyone had any experience with an Orange 223? I'm half contemplating looking at a second hand frame at the moment. Obvious it'll suffer from brake jack being a single pivot, but are there any other 'issues'?

[Bubba]

Never ridden one but seen plenty going fast on uplift days. A solid bike I suspect.

It's a proper race bike so you'll be talking low bottom bracket and slack angles - great for going full out but will be less happy for slow/twisty freeride stuff.

You can get a floating rear brake arm to eliminate brake jack but i'd try it without first. They can be built up to around 40lbs which would be fantastic but I'm sure that'd cost a lot to do. Haven't read of any generic frame-cracking nastiness or anything.

My disk rotor doesn't sit in the center of my new front disk brake.  Anyone got any knowledge for aligning disc rotors inside the calipers, apart from get a washer and file it down to the right depth.

[Bubba]

You really want to move the caliper, not the disc. The disc should sit on the wheel mounts with no washers in between the disc and the mounting points.

Can you move the caliper on it's mount? Is there some sort of adapter between the actual caliper and the mount on the forks?

Fork & type mount, type of brake and rotor size please, oh yeah and frame model

DON'T file anything yet mate!

Shimano XTR front brake caliper, 2006 model I think.  Forks are Rock shox reba SL.

The caliper is bolted directly to the forks at the minute, which gives them no movement.  When the wheel/rotor goes in it touches one of the brake pads.  It should be about .5 mm further out to be centered and running free.  I did get an adapter with it, but haven't used it because I don't need it to get the caliper in the right position for the forks.

[Bubba]

That caliper is designed to bolt straight on to International Standard fork caliper tabs, but needs an adapter to mount on Post Mount caliper tabs.

I think the Rebas have Post Mount caliper tabs (check online for your exact model) so I think you'll need an adapter.

Didn't the caliper come with an adaptor?

This daddy may be the business for those night rides or pissing off motorists on winter commutes. The rear light also looks good.

wise words.

that's why it dont fit on the one side... i've been in this pickle before.

It's not possible to attach post mount calipers to IS mounts (and vice versa) - you'd end up with the caliper at ninety degrees to where it needs to be.

If the screws attaching your caliper to the fork screw in in a forwards direction (in line with your frame), you have post mount. To adjust them, you need to slacken the screws off and then you'll be able to slide the caliper from side to side. Newer shimano brakes use this system.

I'm pretty sure that 2006 shimano, and pre-2009 rockshox use IS mounts (if the screws go in sideways). In this case, you'll need washers to space out the caliper. You can buy washers pretty cheaply from CRC or an LBS.

This is what I've done, but the washers are too wide.  ie without them it rubs on one pad, with them rubs on the other, so I need to file them down to the correct size.

With the screws loose on the caliper there is very little play to slide the caliper about, not enough to center the disk rotor anyway.

[fatdoc]

dont file.

thin washers are near zero pence.... any LBS will have them (hope brakes use tons!!) and you have a  brake that you can sell / move onto another bike... it will also be far less time consuming!
