for those running studded winter Tires on your altitude what width of Tire will the altitude take?
2.6 will fit and 2.8 may fit the front but not rear.

Having a 170mm fork, I want to run a longer travel bike with a 8,5x2,5 shock length. Probably a DVO or a Suntour Triair.

I went through this thread and I have found precious info. As stated, no need for offset bushings when installing a 8,5 shock and staying in position 1 (ride9).

But I would like to be able to run position 1 to 5 (or at least 3rd mode).

What are the exact specifications for the offset bushing to achieve this? Do I need 2 pair of bushings? I am new here and not familiar with RM bolt and bushings.

Thanks so much

Have the same question. If someone can post the details on the offset bushing, I'd be forever grateful. Thanks!

If you want position 1 to work like position 1, you need offset bushings. There's a 6mm difference between the eye to eye of the stock shock (210x55 mm) and the one you're proposing (216mm). Offset bushings are like 2-3mm per side if i recall correctly. So I'd probably do them on both sides.

Worst case and you end up preferring only 1 set, offset bushings wear a little faster than stock ones so its not bad to have spares if you will ride the bike a lot or have it for a while.


Also, if you have reach to spare I'd consider a forward offset seatpost to counteract some of the slackening of ESTA you're doing (although I understand that's a lot more money than 2 offset bushings!).

Anyone know off hand what the stock crank length is for a 2018 Altitude, large frame?

Looking to upgrade but I am nowhere near my bike to check!

Almost certainly 175mm. Don't be afraid to run a shorter length though.

No qualms here going 170mm if stock is 175!

For anyone wondering, I did eventually get home to my bike and the cranks on a '18 C70 SRAM are 175mm.

X-fusion is making me a custom Vector coil for the 210x55

Stock A70 XL other than Chris king BB and headset, stans arch rims

nice! what did you get in between this and your last one?

I have just retired my Altitude. Great bike, but fancied a change, so currently have a 2020 Norco optic (which I am very much enjoying).
