i wouldn't worry too much about an alternative crank throwing out the look of a matching group.
for me, if the mech's & shifters match, the brakes & levers match, you've got a matching wheelset & suitable finishing gear the rest will fall into place nicely & give a good looking build. there are a lot of factory spec builds out there already that will have full groups from hubs to mech's to levers and back down to the brakes so having something a little different will never be a bad thing.
I'd agree, to be honest (although I thought it was all M739 - but no idea with the cranks
). For me I bought this as a frame new and lugged the bike box a mile or two home up the hill from town. So I've never really had that 'factory group set' chip on my shoulder. Just kind of my bike really. The original rockshox only got fitted because they were on the Saracen first.
I kind of like the history that you aquire with a long standing bike as well. I know the rims don't match and I know why they don't match (best mate took the old sunset rim out on a pub car park by accidently riding in to me while stationery!) and also why the spoke nipples on the rear are weird (asked for purple but LBS, bitd, only had blue and red so they used those!
) Kind of makes it 'my' bike, tbh. Which I like.
