Need a new bottom bracket

Just checking in here before I order one and want to know if there is any difference between road or mountain BB.  Blew out the stock Shimano road @2100 miles and looking for options. 68mm external

I went with Shimano BB60 which has very good reviews @$20. Hopefully the plastic adapter will let me torque it down bb w/o issues. 

http://wheelsmfg.com/ \n \nFor future reference. I personally got one for 20% off on presidents day. So I'd imagine during other holidays they have sales as well.

Thanks for the link I wasn't aware of that Co. Looks like nice stuff. When this chain wears out I will upgrade cranks, front and rear mechs then pick up a red BB from them. First order is 15% off for signing up which is pretty good deal plus made in USA!

You'll have to get the Shimano adapter as well: https://smile.amazon.com/gp/product/B00R1OZJBI/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Expensive, but much more durable and serviceable (special grease tool required) than stock Shimano junk. If you inject fresh grease every 6 months or so, it should out last your bike.

I'm assuming that you have a threaded bb shell. I also have the Wheels MFG bb in my unthreaded press fit Lemond Washoe. It's a bit tricky to install and service. I had some creaking issues with it. I cleaned the bb shell and re-installed it. That fixed the problem. The tricky bit is that the drive and off drive bearing shells are threaded together. You have to press in the drive side, then screw and torque, the off drive side into the drive side. There is no easy way to replace or service the bearings on the Wheels MFG though.

Thanks for the replies, I thought about the CK but couldn't justify it with current build and budget. The grease injection sounds like a great way to service. Yes I have threaded 68mm. 

What ruined my 4700 stock Shimano BB(Tiagra Grade) was sand impacted the outer drive side and worked it's way into the bearings. I had an intermittent clicking noise for awhile so I think it was on the way out for awhile. My last few rides the noise was constant and when I pulled it and inspected the bearing slop was quite evident.

Do you guys pull your BB every so often to inspect and clean? This is something I might work into my maintenance routine. New Shimano is Ultegra grade and allegedly has better seals. I'll post some pics when it comes in.
