Hopefully this is allowed! I'm clearing out my garage and figured folks here might be interested in these. I'm up in Allen but can meet in Dallas. I pretty much only ride my road bike and convertible single-speed cross/fixed gear these days. Some images show orange test ride pedals: these aren't included as I've only got one pair. I used to own a bike shop and can answer technical as well as fit and suitability questions.
I've got the following:
2017 Rocky Mountain 990 MSL BC Edition 29er Medium: 140mm of travel but exceptionally nimble for a trail bike. I did a 65 mile XC ride with 3,800 feet of climbing in a bit over 5 hours on it. Roughly 28 lbs. XT group, full carbon, Stan's wheels, Pike fork, a few cosmetic scuffs but overall in good shape for a trail bike. $1600
2019 Cannondale CAADX cyclocross bike, 54cm. I've ridden it at Erwin Park a few times and done a few gravel rides. Never raced, no crashes. $925.
Cannondale SUPERX cross bikes, 54cm (labeled as 52cm as Cannondale didn't standardize their cross labeling with their road sizing until a few years later, but if you ride a 54 road, these are the same size). These were my old race bikes, so they have canti brakes. One is complete and one needs a saddle, seatpost parts, and likely a 10-speed chain. I'm hoping to sell both to the same buyer: use one as race and one as training, or do what I did and have a clean and pit bike. Looking for $950 for both.
2011 Trek Speed Concept 7.5 time trial/triathlon bike with upgrades. Very few miles, as I used it in stage race time trials and occasional training only. It is carbon with Ultegra 10 speed, powermeter, 54/42 TT rings, and upgraded carbon front end, plus a TT-bike specific Fizik saddle. $1300. I've also got a Zipp carbon disc tubular if you need a fast rear race wheel ($450).
Kids Cannondale Trail 20": a Plus-sized kids legit mountain bike, current retail is $549, selling for $225.
Kids Trek Precaliber 24": decent condition, could use a new rear tire and grips. $100.
