I’ve had this discussion with a bike shop owner when I was looking for an old model Hightower.
He indicated the manufacturer will usually hand their largest volume retailers the excess stock to sell at a discount and the smaller bike shops lose out that way.
He also indicated that stock management has tightened up and there is less excess stock generally at the end of the season.
The outcome is that old model deals may be harder to find. Anecdotally, I also mooched around for old model Scotts, Rocky Mountain and Ibis and again old model deals were few and far between on those brands.
Cruelly, I suspect there may be a surplus of Hightowers in 2020. Reading the US forums in particular, it has fallen flat. Being fugly and the media referring to the Hightower as a “dad bike” has not gone down well it appears.
