Spanish BB Length

(1/7) > >>

Hi Everyone,
Yesterday mid way through a dirt session at my local spot, my bike made a loud cracking sound originating from the BB area, my bb has been making creaking a couple of days ago.

I'm running a two week old Eclat Spanish BB, prior to this, i have never had any issues with my BB prematurely 'shittin the bed', i couldn't think of what i did wrong installation wise.

I then took my entire Cranks/BB off and saw that the seals on my bearings are all knackered. I then measured the tube spacer (48mm), both bearings (18mm) and my bb length is 68mm.

This comes to my question, why did they provide a tube spacer that isn't long enough for a standard BB Length? my conclusion is that I actually had to install a 2mm thick crank spacer inbetween my tube spacer and bearing on the inside of the frame?

I reckon what caused the seals to be knackered was cause there's a 2mm space in the BB shell that was allowing the tube spacer to be moving around?

Who else have encountered a similar problem? pretty bummed cause i waited ages for the eclat bb to be delivered to me and i have to the same again...:)

there's a pretty big lack of standards in bmx. i ran into the same problem on my old FBM frame but i just stuck an extra 5mm non drive side spindle spacer inside with the tube spacer

nailbomb:
yeah man, true that, wished i had actually double checked on the measurements!

Tall Opinion:
I don't think that would cause your bearings to fail quite that fast. I've heard of lots of people not running the tube spacer at all and being fine.

GUMP_:
I don't run the tube spacer every one I've ever installed has always been a few mm too long
