Welcome to our forum. Feel free to post a message.
I'm thinking of replacing a Campag square taper 39/53 with a compact c/set, but undecided about outboard cups, especially Power Torque with bearings pressed on to cranks, none-self-extracting cranks and bearings exposed to winter weather.
Alternatives (not Shimano!) seem to be
- Stronglight with sealed square taper b/bracket
- FSA with outboard cups but separate bearings and self-extracting cranks?
- SRAM ditto?
Any thoughts from fellow Enigmatics (and Mark/Jim) on comparative wear/life of any of the above, suitability for Enigma bottom bracket/frame, and any other relevant comments?
Sram would be my choice, self extracting bolts too!
bad heel clearance on sram though.
Thanks Mark, I was leaning towards SRAM.
What's this about heel clearance, h? Do you mean heels against chainstays or ankles against crank? I've never had such problems before, unless I deliberately twisted my foot off-centre on the pedal. Do you use cleats with float? Having been brought up on nailed-on metal shoe plates (you had to get 'em right or suffer bad knees), I've always used 'no float' as I prefer the more solid feel on the pedal.
I have 165mm FSA cranks with maximum float and I simply deal with the issue of scuffing the crank with my heal by covering these with electrical tape.
I rather tape over the cranks than knacker my knees!
I've not come across any heal clearance issues with Sram.
Thanks guys, no problems then - nor with my knees, Arran
Happy Christmas and a safe New Year
Have just noticed this thread and not sure if this is of assistance. I live in Australia and last year put together a bike using various components based on an Echo frame. Used Chris King BB with Sram Force Compact crankset (172.5 crankarms) Has been fine for me.
