Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

New to me Di2 7970 or wheel set?

Hello all, looking for some advice.

I have a 2013 SuperSIX with Rival that I love. I have the opportunity to purchase a friends Di2 7970 because he is upgrading to DA 9070, and install it on my SuperSIX. The purchase price for the Di2 7970 is $1000.00 for the full group, including pedals. I am sure this is a great price, I am just wondering if I should use the money for a great wheel set instead of the group set.

would you go from SRAM Rival to Di2 7970?

or

would you go from Fulcrum Racing 7 to nice light climbing wheel?

Thanks for the help.

I've never had any issue with using the 7970, but if you love the bike with SRAM, then I'd first upgrade the wheelset. And $1000 for the likely well worn 7970 doesn't smack of a great deal to me.

the group set is brand new, its an take-off from a new bike. As far as SRAM, I like it, but it doesn't really matter between Sram and Shimano.

The fulcrum 7s are a pretty chunky wheelset, 1850 grams is probably 250 more than it needs to be. Buuut...the answer is Di2, no doubt about it. Why? The best you can do with an Al wheelset is ~1500g for an all-around formfactor, maybe 1200g for a non-aero "climbing" wheelset. The performance difference you'll see is marginal. Carbon rims will be faster but there you pay much more and sacrifice longevity. Otoh, Di2 will be a huge upgrade from rival, and certainly not something everyone else has. Finally, it sounds like you're getting a killer deal for Di2 - I'd pull the trigger on the group and put money towards wheels later.

If you don't get the 7970 will he sell it to me for that price?

Yeah. And if that offer includes the crank too, it seems like a pretty sweet deal

That's a no brainer.
