    140 or 150mm on my 2014 Sensor ?

    I'm bringing the 130mm GT to my lbs for a fork travel adjust on Monday. What do ya think.. 140 or 150mm? To be honest, the main reason is to slacken the bike out- just feels quite steep at the current 68.5 My concern is that at 140 I won't notice a difference.. or that 150mm will make it feel less nimble and fun. Yes, I do still have the Sektor on there..will upgrade in due time, but for now I wanna see how more travel feels with the current fork. I'm getting it serviced, so I figured do it at the same time.. Thoughts? (Btw, bars 760, stem 60. Thanks all.

    Adjusting to 140 will give you an even 68 degrees, 150 would be 67.5. It's important to remember that you'll aslo be adjusting the BB drop, effectively, which affects the stability of the bike, as well as the bar height and seat tube angle. I think I would try 140. But that's a personal call.

    Yea..I'm definitely leaning toward 140 for now- thanks. I wonder how much of a change in bb height there'd be..I like the low height right now- hopefully it's a very minor difference.

    Sorry for the hijack.
    Can you explain me that need/procedure? I Have a 2014 Sensor and I am exactly in the same position, I'm going to change from my 130 fork to 140 or 150. So that implies that I have to change the BB drop? Can I do it at home? Thanks!

    The bb height will automatically increase when you add travel to your current fork.. just not sure how much, but it's probably just a matter of millimeters. Lots of people adjust the travel at home, but I'm not too mechanically inclined and would rather my shop take care of it while they're servicing it anyway.

    Yep. A friend of mine has a travel adjust Auron on his Sensor, adjustable on the fly to anywhere from 130 to 160. At 160 the bike feels invincible, but it takes some serious commitment in turns.

    There's a formula for figuring out how much your BB will rise or fall with a change in the axle to crown on your fork, it involves pi and the length of your chain stays and the amount of change. I don't remember exactly what the formula is off hand, but yes, it's millimeters.

    If I needed 160mm in the front I would get a Force.

    Personally I run a 140mm Pike and its been perfect.

    Suspension is not only a question about travel equally important is the quality/control of the travel.

    I recently installed a 150mm on my 2015 GT Sensor Elite and I think you could go with either setup. The longer you make it the more slack it gets and the more it suffers tighter turning capability... or maybe even how well it turns / flicks. But, if rough straight terrain use is what you desire then going 160 works.

    One thing I've noticed since I've gone to 150mm is that I'm running the rear with more pressure now and less sag to steepen the angles again and gives more bump absorption potential (too). So, even 160mm seems like a good option to me now. Not all forks perform the same throughout the travel, that can also be a factor.
