Road Groupset Weight Comparison
Groups Road
SRAM made claims to have produced the first sub 2kg groupset in their 2008 Red offering. However anyone who had taken the time to add up the component weights would have found that Campagnolo Record 10sp was under 2kg in 2007.
In 2011 SRAM Red still have the lightest group available (by 26g) with their BB30 crank option, however the BB30 cranks are not compatible with many bikes as yet. The Campagnolo Super Record group at 1875g is the lightest group that can be fitted to any standard bike.

cThe Di2 system requires a battery and electrical cables which cannot be cut shorter. Together the battery and cables weigh 217g for 'medium' length. Typically the weight of standard shift cables would be 80g so we have added 137g to the weight of the Di2 group to take into account this difference.
