In the bike manual it states I have a 'Truvativ Elita, 68mm BSA' bottom bracket. Seems a little vague to me.

So, which tool do I need?

Ideally something that I can clip into a socket wrench like this and NOT one like this

Advice much appreciated

Thanks

So with no description as to what you wish to do it's kind of hard for us to give you advice. From the links provided we might assume you wish to work the arm preload bolt. But you know what assumptions are. BTW if the tools linked are the right ones for your need DON"T use any leverage beyond your fingers in applying preload to the arm/BB. having a socket fitting is an invitation to ending up with massively over loaded bearings. At work we use the Park BBT-10.2 tool for the mentioned preload bolt. It does have an 8mm wrench fitting but we NEVER use that feature as we know better. Andy.

I want to remove it, dismantle it, then put it all back together again for no other reason than I want to get to know my bike.... and maybe there's the cleaning & greasing aspect too. I can't do any of this without the correct tool to remove the cups. Any ideas? Thanks

Rambino

Yes, you're right....a terrible title to the post, apologies.

The first tool is, as Andy described, just used to preload the non-driveside crank of a Hollowtech II crank and should only be tightened finger tight and not hard finger tight at that. The torque spec is only 6-13 inch-pounds.

The second tool (Park's BBT9) is used to install and remove (using the larger end) the bearing cups in the frame. The other end is used to preload the non-drive side but should, again, only be tightened with fingers.

Rambino

I've just ordered the BBT-9 from Amazon for £15 (on prime) which seems like a good deal to me.

And I'll risk using the 8mm "wrench" for the preload bolt.

Thanks both

There is pretty much zero point in doing what your planning, as the BB you have is a sealed unit, which isn't designed to be disassembled, only replaced. It's not till you get to Hope level components that they are re-buildable.

If you want to pull the crank, that's easy (an may be worth it to grease the spindle), but your going to get no benefit in pulling the BB, as if you know how to unscrew a bolt, you know what the outcome will be.

For the tool, shop around a bit more, here a cheaper one. Park Tool BBT9- Bottom Bracket and Crankarm Tool (HollowTech II) | Tweeks Cycles

If you want one to use with a socket you should get the BBT-19.2. Your GPX/SRAM installation won't have a pre-load adjuster, just the bolt to install the non-drive side.

OK, first of all, I never meant that I wanted to completely dismantle the BB so I could see it in all its exploded view glory - I just meant that I wanted to slide it out, strip the bike back a bit, learn a little in the process and maybe give everything a good clean/grease in the process.

I guess I just like knowing how everything is put together.... and collecting tools too.

Also, if you're as good at shopping around as it would appear you are (too late to cancel my order unfortunately) what's the cheapest 'SRAM Force 10' rear mech you can find?

The lowest I've come across is £56

If you can find a good condition second hand one, then I'd pay £30 - for a new one I was hoping for around £50

Good luck!

Really? You really ask others to use their time and effort to save you six quid? At least you are in the right forum.

Rambino

Do you know what the word facetious means?

Actually, don't answer that, it was a rhetorical question.

Of course you don't know what it means.

Whoosh...

jimc101

If you have found one for £56, that's pretty good. From a quick Google search, if you drop down to Rival/Apex, which still support 10 speed, you will be looking at £35ish new as Force 10 is an obsolete groupset.

AnkleWork

Sure. Keep running from your own words while I stand on them.

Rambino

Why did you even bother entering this thread if all you were going to do was be rude and disruptive whilst not contributing anything in the least bit constructive?

I don't know, maybe trolling is your thing?

AnkleWork

Your projections reveal much about you. Thanks.

Look, I've just turned 32, I'm too old to be arguing with some kid on a bike forum.
