Truvativ Touro Triple 30/42/52 uses which bottom bracket?
https://www.nycbikes.com/item.php?item_id=297
Ok all, I am going crazy. I wanted to call the shop above to find out which bracket I need to buy but they are closed. I've found other bikes that have this crankset on it and they either use a Truvativ BB or a Shimano 4 taper (?)
I can't find anything on google. Anyone else have any ideas?
(sidenote: I now that there are sizing variations that will come into effect, but I am just tyring to find out what type of BB I need, not really the specific size.)

Square taper, according to the specs on the SRAM website: https://www.sram.com/en/truvativ/road...uro/triple.php
I think the Shimano BB-UN52 is a 105/LX quality square taper - long time since I've needed to look for one!

Nashbar only sells 70mm sizes.
Do they come in 68x118? Or am I missing something. I was pretty sure I needed 68mm.
what exactly is the measure of that first number? I've hit sheldonbrown.com but am not finding where that number comes from.

The first number is the width of the bottom bracket shell, and yes you probably do need a 68. (70 is Italian)
Check out https://www.sheldonbrown.com/gloss_bo-z.html and scroll down to bottom bracket for more info

Shimano makes a UN52 and a UN53 bracket. Specs look the same to me. How can i find out if they are interchangeable?
