The Schwinn Sierra 21 is a casual bike, the middle offering in the young rider-oriented Sierra line. This model is a step up from the Sierra 7 in that it has twenty-one speeds instead of seven, and has a sealed bottom bracket to keep sand and dirt away from your bearings. That being said, this model lacks the higher cost IG3's internal gear hub (having a derailleur system instead), suspension fork (having a rigid fork instead), and double wall rims. Features shared throughout the line include dual density grips, which are made to feel good on your hands. Another shared feature geared toward comfort is a lightweight aluminum frame, which has a geometry of sixty-eight degrees.
