1/8" cogs
i apologize for the lack of product available to the masses while we go through our move across the country. i assure you 1/8" cogs are available. perhaps the BTI site is a little misleading. they have chosen to only carry the 3/32" cogs. small company, ya know. as soon as our product makes its way to our new location we will be able to sell directly to the end user. good news for all those interested i hope.
we are available to answer any questions or concerns you may have concerning anything fixed. our email and phone numbers are at the bottom of every page on our website (which is due for a major upgrade, -ps.)
here's one answer: use blue loctite (243) on your cog bolts. it keeps them from loosening up from the slight back and forth motion of the cog. this goes for both LeVeL hubs and disc convert hubs.
also, the three bolts on the LeVeL dont take any of the drive force. the knuckles do that.
