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.”
