Just another person in search of elusive BB size
Hey All,
I am currently building up an old Merlin MTN bike, Everything about this project is unconventional because either how I am setting it up, (seven speed w/ ridgid threadless fork) or because this frame is so damn outdated (we are talking early 90,s here.. ancient history, perhaps you remember the Clinton admistration? Or when 'Dirt Rag' was simply B&W?)
So, I am looking for a BB with a shell thread of 68 and a tapered spindle leangth of 135 or so. The cranks will be single chainring upfront and seven speed rear freewheel. The cranks have to clear the 112mm of chainstay width, these chainstays are bulky hence the long spindle. All the spindles I have laying about are too narrow.
So Who still makes it? Shimano? and where can I buy it? some of you brainiacs were very helpfull in my search for a threadless 1" head set, so Thanks to that!
Will post photo's when this project is done. It is gonna be "special"
Thanks to all comments,
Jt

i forgot about Echo products (for trials). they make some sweet BB in wide sizes...external to boot! i do not see why they wouldn't (oops, double neg.) work for most forms of riding, trials riding is pretty harsh on BB's so i figured why not. i would have bought one of these but i ordered a fsa that will suffice.

- Maintenance-free sealed cartridge assembly with extra seal keeps out dirt, mud, and water.
- Also allows installation without adjustment.
- Offset axle (to the drive side) to ensure maximum clearance for front freewheel users.
- Ideal choice for trials riders using square taper cranks due to its solid axle, good price, and relatively low weight.
- Steel cups for maximum durability.
- Includes crank bolts.
- 122.5mm or 127.5mm axle length with 68mm shell available, to fit a variety of setups.
- Weight 310g.

(watch out, the site is addicting...you might become a trials rider if you stay there too long)

Hmmm that 127.5 might be worth a try, I think it could work. Yeah, I hafta clear 111/112 with the inside of the crank arms... they Bulge out in that area for some long forgotten reason.
This Merlin was the state-of-the-art frame in it's day, I am sure it was adorned with quality componentry at one time...
thanks for all the replies "mx_599".
