I know this is a bit off topic but I want a sirrus 6.0 2021 but I do not think the rims can handle my weight. I weigh 245 and I have a body fat of 12% so I'm not fat but a lifelong bodybuilder. I would consider the sirrus x 5.0 but the crankset is to small for my leg strength. I have a 2009 stumpjumper with a crankset of 44/34/24 up front. I have been riding this on gravel and find i need more gears on the flats. The sirrus 6.0 has the right gears but can't handle my weight and the sirrus x 5.0 doesn't have the gears I want. How do I solve this problem? Can I put the crankset from the 6.o on the x 5.0. Based on what I've read putting the rims from the x 5.0 on the 6.0 isn't an option.

Lol. You are overthinking this.

Stock Sirrus 6.0 will handle your weight just fine. Your leg strength has zero effect on the crankset.

The Sirrus X version handles wider than the other sirrus models.

Think of the Sirrus as a flat bar road bike and the Sirrus X as a flat bar gravel bike.

I have a 2020 Sirrus 6.0 and a 2018 Sirrus Expert Carbon which are essentially the same bikes. I was 216 lbs riding the original rims ( AXIS 2.0 Disc) on the older bike and it was fine. The 6.0 comes with DT Swiss R470's. Can't see it being an issue.

I am running 40mm front and back on a 2011 sirrus sport. Gonna put some 50mm up front soon.

Can I ask why you have two of the almost same bike two years apart?

At just over 6' and after having ridden the Sirrus Expert for 13 months, I found the L to be a tad small for me and wanting to stick with the same brand and model, found an XL in a new bike. I have since sold the older bike and find the 6.0 fits my frame a lot better.

Thank you! I'm between 5'9 and 5'10 barefoot with a 30 inch inseam. Do you think a Medium or Large would be better for a Sirrus X?

According to Specialized...for Sirrus: 5'5" - 5'9" M 5'9" - 6'0" L 6'0" - 6'4" XL

As I said, at just over 6', I found the L too small..but I also have a 35" inseam. New bike is XL.

Best to find a bike and try it our beforehand. Good luck.

Take note, sizing between Sirrus models varies a bit... For example, in medium:

• Sirrus 6.0, x 5.0 & 4.0 reach: 384 and stack: 631
• Sirrus x 4.0, reach: 382 and stack: 635
• Sirrus x 3.0, 3.0 & 2.0, reach: 398 and stack: 593

Nothing huge, but to some it may play a factor. I'm 5'9" with a 32" inseam (not pants) and I was between a M/L on the Sirrus x 5.0. Went with the medium and it feels great. Easier to "extend" a bike, then to shorten it... within reason.



A medium x 4.0 an

the geometries are not the same. For example a x 4.0 and x 5.0 both in medium have different stacks and reaches.
