It's a shame you can't really size the trek just by reach. Their obsession with long seat tubes prevents you doing that.Reach is much better on the Transition Spur--it's OK on the Top Fuel and Epic EVO, but could be better. Other bikes in the class of the Spur: Norco Revolver, Mondraker F-Podium.
Agree. TF is a long-ish travel xc race bike. Spur is a short travel trail bike. Two different approaches.I own the TF and have ridden the Spur. The TF is closer, IMO, to the XC end of the downcountry spectrum and the Spur is closer to a trail bike.
Jeff Brines does a lovely comparison of the Spur to the new Top Fuel he's had a bunch of time on:
