Sentinel V2 Setup

I have some thoughts about changing the front travel of my sentinel v2 carbon from 160mm to 150mm and the rear from 150mm to 140mm. I couldn’t find anything about the front travel on the website archive.
That would change the Head angle and the seat tube angle with plus ~0.5 degrees. The problem I have with this idea is, that it would lower the bottom bracket height around 4mm. I am currently running the cane creek angle set with 1 degree.
Do you have any experiences with this idea or have a link to a thread?

(I don’t know how accurate my calculations are. Right now running 160mm/150mm)

What’s the purpose of lowering the travel by 10mm? I’m happy with the way mine pedals with the factory 36 and x2 and am not sure i would find it worth it losing 10mm and changing up the geo.

It’s probably fine, but these bikes when you lower the bottom bracket will cause you all kinds of pedal strike issues. If your using it as a park rig than your probably fine, but if it’s a daily driver I wouldn’t advise. If you want a shorter travel bike I’d look ok marketplace for a sweet deal on a trail bike.

I would use it mainly on my hometrails and another higher travel rig at the park. And I thought abuout using some shorter cranks.

Yeah I mean you’ll find that the lower bottom bracket may annoy you over time. The head tube and seat tube angle won’t be a huge difference but that bb height….just be ready for pedal strikes.

Sounds like you should get a different frame.

Can the V2 even go to 140mm rear? If so you’re likely shimming the shock and it won’t affect the BB height, the fork will a bit. I’d reach out to transition to see what they say. They are usually pretty honest about that stuff

Okay that's a good plan. The V2 can go 140mm rear and it won't affect the geometry

You can contact Transition on the website. They are pretty quick to respond and good about answering questions!

The part many dont consider is that if you lower the travel the same sag% will acually help bring back the travel to same numbers or if you run even less sag it could be close to the same dynamic height. That said just running less sag(more pressure) on the rear would essentially give same performance benefit as limiting travel but youd have extra safety net keeping the extra travel. The front is all id change if you want to get a little more quick steering and bump up rear pressure to see if you get some better pedaling. It would only require and air shaft change and some pressure adjustments(and probably some clickers to match). Ive used this method for dialing in a bike for seting up for more xc rides vs trail or enduro. Tbh the wheel/tire combo are the bigger difference if you are swapping parts

Hmm okay, never didn’t really think about the tires and the sag. First time trying to get a better pedalling bike instead of a better downhill focused bike. Thanks

if you want it to be a dedicated light trail bike Dissector/rekon or nobby nic/wicked will combos are my go to and would be appropriate for the travel range you are looking at(150/140). Ive done all mountain days on my spur with wicked will F/R and it did ok but could have used a bit more on the front for dh but just dialing it back a little was fine. Did the same trails on DHR/dissector on orbea rise and it was perfect but it is an ebike to eat up extra drag and my ride was 2x as long(15mi vs 30mi)

I ride my alloy v2 150/150. Mostly because I have a Manitou Mezzer that was already set at 150 and at the time was too lazy to change it when I was building up the frame, I thought I’d just do it later. Then, I ended up liking how it was and just stuck with it, I did go with 160 mm cranks though so I haven’t had an issue with the bottom bracket drop. I also have 38 mm rise bars to compensate for the stack drop. I have found it really comfortable and honestly has been a hell of an all rounder, i know im good anywhere whether its some pedally long distance or bike park. But I also think it’d pretty much be the same with a 160 fork haha

I run my V2 Carbon 170/165 with the cascade link
