New bike project

Haha yeah the more i look at it the more I think its not been used that much

 

[gazza81]

I should see what you can find at a lower price with good reviews. I think there are some cheaper Shimano units that get good press.

Is that what im after?

Theres different types, flat mount post mount etc

Also i want to keep a eye out for a used single front ring, or a double or tripple i can strip to a single, looks like mine is welded together or something and unable to split them

Any ideas on what I need to keep a eye out for in terms of fitting?

Do you really want a single front? What size? If you don't want to shift at the front, why not just run in the middle chainring without shifting?

Yeah i do ha
I like the less congested bars, less maintenance/things to go wrong, cleaner look
It cant be that much hassle to change it or costly surley?

Size wise i was just going to keep my middle ring if i could

I think what you've got on the bike is the older less common now ISO mount so you'll need an adapter but finding one might not be easy .

Oh right ok, is that going to be the same for any upgrade calipers

 

[Cycleops]

'fraid so. Perhaps @Yellow Saddle might be able to help you out with where to find one.

 

[gazza81]

Ok so ill wait on the calipers for now as i find them abit confusing, but i would defo want to upgrade them soon i think.

Sorry another question google wont answer for me, can i replace my cartridge type for any other type on crank set once its been removed?
Ive seen one quite cheap that might be worth looking at

Generally, yes. You need two spacers on the drive side and one on non drive. That should provide enough width for crank. Sometimes you need slightly different width spacers to get chainrings correctly positioned for front derailleur to work perfectly. A bit of experiment is sometimes required

LBS. When I asked mine if they had any, the response was 'how many pounds* do you need?' as they hefted a box full of the things out of the workshop. There's so many going spare, precisely because everyone's moved to post mount. Just make sure you get the right size for your rotors.



*lbs, not £.

Ok thanks, what is it im asking for? Does it have a name or just IS to post mount?

IS to post mount disc brake adaptor. They come in different rotor sizes (140, 160, 180mm) and will cope with different sizes depending on if they're used front or rear.

You can reuse the ones already on the bike. Maybe replace the rusty screws there, that's all I'd do.

That's a Hollowtech bottom bracket and crank set which should be fine if the MTB type. The bearings sit outside the BB. This set up will be lighter than your current one.
Thanks to @winjim for that info on adapters, I couldn't see any on line.

Regarding brake adapters - this is what I used on my self-built touring bike:

I use M6000 hydraulics with 160mm rotors.

Ok thanks
I asked him to send a better picture of the teeth because the picture he's got is blurry, he hasn't bothered!

I think I figured out the bike has got the sealed cartridge Square taper bottom bracket.
there's a couple of crankset on Amazon for about 40 to £50
