Geometry- this frame was developed as an out and out race bike, and the geometry definitely suits that description. low and slack geometry matched with a decent wheelbase leads to an incredibly stable ride on high speed sections and always inspires confidence on the steep stuff. Suspension- when paired with the CCDB, the linkage driven single pivot performs as well as any frame on the market. Both geometry and linkage wise the frame is very comparable to a TR450, but after riding both frames fitted with a CCDB i would say that where the TR450 completely flattens the trail the Scalp instead offers a little more feedback and feeling. Simply put, to get the best out of this frame you really need to spend some time tinkering with the shock. The frame was developed with the use of a CCDB in mind because with a shock this capable there is no need to over complicate the linkage, for example, bottoming out too easy? just increase the compression damping. Price- the current scalp frame is around half the price of most boutique DH frames, which for a world cup capable downhill frame is amazing value.
Performance wise when compared to a TR450 you can notice a slight increase in flex, but personally i have never found this to be an issue. Also, whilst it can be tuned to become quite an efficient pedaller, this does hinder the suspension over rough terrain, so it will come down to whether you want to burn it on the flat or through the rough stuff. other than that, It does go through DU bushes and top link bearings quite quick, that being said, this is with regular pressure washing and constant British weather, and the overall simplicity of the frame makes replacement a really easy job.
Overall, with both the price and performance in mind, i don't think that you can do much better than a Scalp for the same amount of money without going second hand. Plus, paired with the CCDB it gives you the ability to tune the bike to perform exactly how you want it provided you're willing to take the time setting up the shock.
