New Shimano 105 incorporates many of the benefits that were originally developed for Dura-Ace 7900 series and integrated into Ultegra 6700 series. Overall, performance and durability is enhanced while the entire group manages to drop almost 30 grams from
Strengths: Price is great
Front and rear shifting is great at this price level
Love the Crank... really stiff
Weaknesses: Rear shifting lags a bit and is probably impossible to get dialed in perfect
Front shifting still has chain rub in taboo gear combinations
I switched out from a full sora groupo to 5700 since I wanted the extra rear cog for climbing. The upgrade is noticeable and it didn't cost me my life savings. Defiantly a good groupo for a training bike but probably not the best for racing.

Bottom Line: Really hard to complain about this group set at it's price

I can pick up the 3 components for around $450 or so, remove the new 5700 and more than likely fire sale it for $ ... Read More »

If I tune it in a way that the bike will shift well into the smallest cog then the middle cogs click annoyingly when riding.
If I tune to get rid of the clicking, then I can't smoothly shift into the bottom ring! I've yet to fi ... Read More »
I'm revamping one of my bikes for commuting duty. Its got 105 5600 series STI shifters and Tektro brakes. Although there is adequate clearance for Crud fenders between the bridge and the tire, the thicker Tektro body swallows it up. I'm thinking of replacing the Tektro with the slimmer 105 5600 or 5 ...
