Compact to Standard

[zenbiker]

With Fuji Speedway enduro on the 24th I need to change back to my STD crank (53-39) from the compact (50-34) Can I keep the same chain length?
I had room for a 28 rear cassette! But will run a 25with the Std.
I think I should be OK

PS Any new "wimp" comments about compact cranks with a 28! are welcome . My riding buddies have run out!

I'm no expert but when I switched (both directions) I never bothered changing chain lengths...seemed all right.

By the by, have you considered just changing the cassette to an 11-23 (or 11-21)? 50-11 is a bigger gear than 53-12. Would save mucking around with the cranks.
