Deviate Cycles - Press Release
@deviatecycles: It looks like your chainline vector crosses the rear axle to pivot point vector somewhere forwards of and a bit above the pivot point, so it's at around a 45 deg angle from the rear contact patch (which would be 100% antisquat) - correct? But as the idler is on the pivot there is almost zero chain growth. The only downside of high pivot points appears to be high brake squat - but I suspect the huge decrease in unsprung mass gains you back as much grip as you lose (whilst also maintaining better geometry when braking).

Deviate Cycles - Press Release
I need to investigate the theory on this but the analysis I've been on other high pivot idler bikes is the same - zero or negative kickback despite ~100% anti-squat. Bike looks really great! I'd take a bit of length off the seat tubes but the reaches are fairly long as it isn't a big deal unless you've got short legs. I feel like the head angle should be slacker but I don't know how much stability is gained from that very low centre of gravity due to the gear box and shock down by the BB and the fairly long chainstays (even longer once into the travel) so it might be perfect already. I like that the seat angle is a true seat angle, so it is a real 75 deg at pedalling height - so many bikes claim to have a 75 deg seat angle but only with the saddle level with the head tube (and no-one's legs are that short!), with the honest effective angle a few degrees slacker.

Commencal Supreme SX - Review
@FindDigRideRepeat: Works Components make angle adjust headsets that fit the Nomad - you can go up to two degrees slacker with them. My Banshee Spitfire now has a sub 64 deg HA when set up for uplift days.

Santa Cruz Nomad 4 - Review
@fussylou: You can't. The best you can get off the top link of a VPP is flat then steeply rising rate, and most are falling, then flat then rising rate. Driving the shock from the bottom link allows a rapidly rising rate which continues to rise but more and more slowly - basically ideal for both coil and air shocks.

Raaw Madonna - Press Release and Interview
They're probably not shipping to the USA & Canada because of the greater cost of business insurance if you're selling products to that market (which is caused by the greater probability of expensive litigation if a product fails and hurts someone).

The Bike That Won the Championship - Finale Ligure EWS 2017
@Fix-the-Spade: Looks like a High Roller 2 (side knobs and open channel) with DHR2 centre knobs (less ramped than HR2 ones - better braking and rolling but clog a bit easier).

Transition Sentinel - Review
@mattvanders: 160F/140R Spitfire here too. If anything I'd say the fork used to get out of shape before the back end does - though it's now running a -2 deg Works headset for a 63.7 or 64.2 deg head angle (depending on dropout position), which allows it to take on the gnar almost like a DH bike. I did recently realise that the actual vertical travel on a 160mm fork is about 145mm (fork travel x sine head angle) so maybe everything should have a longer fork?

The Wild Scurra 2 Enduro Linkage Bike - Eurobike 2017
@joshdodd: It looks like you get brake squat, as the caliper gets pulled forwards by the disc when you brake and that action will pull the forks shorter. It looks like a double wishbone design (aka four bar) with the pivot point being projected quite a long way in front of the front wheel, a fair distance off the ground, and moving up and back as it goes through the travel. I wouldn't be surprised if this is loads stiffer than a telescopic fork - having just one connection to the frame via the headtube and a load of sliding bushings makes forks very bendy. We just don't know any better because we never ride anything else.

Transition's 2018 Lineup - First Look
@TransitionBikeCompany: I thought I was getting a handle on how geometry changes affect handling but the more I've learnt, the more I realise I don't know - I built my hardtail up to have the same geometry as my full-sus (Banshee Spitfire) when both are at sag but it never felt quite right. Now the full-sus has been further slackened (63.7/64.2 deg head angle) and the hardtail steepened (about 67 deg at sag) and they both feel great. I don't get why - I'll just try to ride my bike instead of thinking! Anyway, your new bikes look great, just my kind of geometry - and everyone should have seat tubes this short now.

Transition's 2018 Lineup - First Look
@RockNRolla92: Are you sure about that? My 170mm Reverb is enormously long! I'm 5" taller than you, with long legs for my height, and riding a frame with a 430mm seat tube.
