What Redditors Say
Best praise vs top criticism for Specialized Sirrus 2.0
Best Praise
+5 pts“I would take the sirrus as its a super convenient bike. If you can bare the a little bit more serious look, i would even vote for the equipped version (should be roughly 100€ more) because you never know how convenient dynamo + fenders + rack are unless you tried”
r/whichbike
ViewTop Criticism
+2 pts“Of those the Specialized Allez. The Sirrus is too upright. The Kline is a pretty bike but it needs a minimum of a few hundred in repairs to get the front derailleur operational. 54cm bikes might be a little large for 5'7" when taking account an aero setup. Making a slightly too small bike work is possible. The fix for a too large bike is sell it and buy one that fits.”

Best praise vs top criticism for Giant Defy Advanced Pro 2
Best Praise
+4 pts“Giant Defy Advanced will take 38mm tyres. That's an endurance road frame. If you need more clearance then the Revolt can do double duty. Have a spare wheelset - I ran 28mm GP5000s on the road wheels and 38mm GravelKing SK on the gravel wheels. Until this model year the two bikes were identical at the front end geometry wise.”

+2 pts“I think the last year the Defy 2 had rim brakes was 2015. It’s overpriced by about £150”
