For sale: 2011 Jamis SixFifty B1 full suspension.

Size 19, which translates to large. For comparison (I am five foot 11 and the bike fits perfectly.)

Color: gunmetal grey

This is the perfect trail bike for riding NJ and NY terrain. The SixFifty B1 is a trail bike, sitting in between cross-country and all-mountain styles. The in-between 650b wheel size is the ideal balance of 29er stability, traction, and roll-over-everything momentum combined with the snappy acceleration and quick handling of a 26 inch wheel. 130 mm of smooth and plush suspension handles chatter and trail hack.

This bike is light! The upgrades brings this bike in at 29.4 lbs including pedals, which is surprisingly light for a sized large full suspension bike and mix of components.


Upgraded wheelset to Stans No Tubes ZTR tubless (both front and rear.)

Shimano M540 SPD pedals
Crankbrothers bar (better bend than stock)
ODI lock on grips (the best!)

Physical Condition: physical appearance I would rate the frame at 9 out of 10. There is some dulling and rubbing of the paint on the downtube near the cable placement, and the paint on the rear triangle does show chain slap. Normal for a used bike. The crankset and pedals do show rock striking from use. Again, normal for a used bike, but cranks and pedals are 100% tight and otherwise in perfect working condition.

Working Condition: 10 out of 10.

Retail cost new $3100. This sale is at $1100 given the bike condition (as quoted by bike blue book, provided below in link) and upgraded wheelset, and other miscellaneous parts.

Overall, excellent bike value and component quality for the cost. This is a low price point to get into a nicely appointed and very capable 650b full suspension.

More pictures available on cl posting. I've done my best to accurately describe the condition, but if you have any questions, please post up or pm me. Thanks for checking out the posting!
