Eccentric Bottom Bracket

I recommend this product
ProsIts the BB youve been searching for. Cheap
A perfect fit for my schwinn sierra frame. Obviously made for the foreign mass produced tandem frames rather than bespoke british ones. Sturdy, not creaky and no complaints.

Cons... but only after a bit of fettling
ProsDoes the job...
Nicely machined part, but was fractionally too large diameter to fit my Thorn, no matter how hard I tried to drift it. Ended up having to knock it out and reduce it down a bit before it would go. No

Is this is a replacement for my Hadon BB on my Dave Yates/ M Steel built Flying Scot tandem?
By

It is a pretty standard M Steel 1980's build but the Hadon eccentric BB that is in it is threaded and while it's OK for now I know I will soon have to replace before our next decent tour. Any help appreciated and thanks also for the SJS crank shortners for my son, work a treat.

Hello,

As we have never sold Dave Yates bikes or even serviced one of these bikes we're going to have no way of knowing if this Eccentric bottom bracket shell insert will be suitable for your bike or not I'm afraid.

Is this comparable with 'Full Speed Ahead FSA Alloy Eccentric Bicycle Bottom Bracket - 200-9030'
By

I can only order 'Full Speed Ahead FSA Alloy Eccentric Bicycle Bottom Bracket - 200-9030' from the US. Can this bracket be used instead?
Full Speed Ahead FSA Alloy Eccentric Bicycle Bottom Bracket - 200-9030 - this offers us no technical information about the BB. We need to know exactly width and diameter.

Goodday,

Just to be sure. If I put this into my newly build tandem, I can fit any BB system like gpx and so on?

Thanks in advance.
Kind regards

Will This Fit A 2009 Rockymountain Hammer 29

HI i am looking for a EEB sleeve for my 2009 Rocky Mountain Hammer, here is the specs
http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2009&brand=Rocky+Mountain&model=Hammer+29%22
Hi,

Unfortunately the specification for the bike you have provided does not give any information on the bottom bracket dimensions and as we have never sold Rocky Mountain bikes or even serviced one of these bikes we're going to have no way of knowing if this Eccentric bottom bracket shell insert will be suitable for your bike or not I'm afraid. The dimensions for this insert are listed within our description so we'd recommend checking those against the bottom bracket shell in your bike first. If they don't match up, all we can recommend is contacting "Greenover Sports" who are the current UK distributor for Rocky Mountain and they may be able to source a replacement but for a bike of that age there is no guarantee.

Thanks.
