Wheelset Upgrade
 

I'm having some difficulty in finding a pair of wheelset compatible with the Sirrus Expert 2016.

After looking for awhile I decided to get the Fulcrum Racing 5 DB but I was told it's not compatible due to the spacing in the axle of the frame, or something like that.

So, other than the Axis 4.0, is there any other set of wheels compatible with this bike? My budget is preferably under £500.

Thanks

If you can't find any definite info on the wheel set you have now , you may need to measure.
Here's a pretty good article on what is what.
Axle standards explained- Mtbr.com
There's a good chance you have mountainbike standard stuff eg 100mm front 135mm rear spacing and QR standard axles.
Measure anyway to know what you have , so you know what to look for.
Are you looking for more durability or lighter than stock?
This should get you started anyway.

Any pair of 700c QR MTB/road disc wheels will fit. Standard 100mm front 135mm rear spacing.

I guess the relevant question here is, why are you replacing the wheels? Lighter? Wider? Shinier?

Can't find it online? ask at a Bike shop.

what do the other wheels need to satisfy the stock ones dont?


How about buying Expensive Tires for the wheels you Have?



;)

Hi, thanks so much for the info. They're indeed 100mm front 135mm QR standard axles. I'm still not sure whether I need to look for something that is up to that standard, under or exactly 135 mm. For example, the Fulcrum have choices of front 12/15mm rear 12x142mm (which is over?) or 9mm QR (is it under?). Pretty confusing.

I also spoke to another LBS on the phone and the guy said the Fulcrum's might fit by adding spaces or something like that. But now I'm wondering if I should put a set of road wheels on a Hybrid like the Sirrus. :bang:



I'm not too worried about the weight of the wheel as I weigh about 90Kg. I am mostly interested in performance, comfort and a general feeling of improvement over the Axis 2.0. Thanks





I think I might have found a decent, compatible set - Ksyrium Elite All-Road. A bit pricey, but I hope they're worth it.
I'm also going to send a message to DT Swiss to see if they have any recommendation for this specific bike.


should choosing a set of wheel be this complex or is it just me?:foo:

At that budget, you can probably look at handbuilt-- which I heartily recommend. My custom set was under $500USD, about 400GBP.

Where do I look for something like this? Thanks

I have the same bike OP and it looks like you've narrowed it down correctly. You need a 700c x 135mm mountain bike rear wheel that takes an 11 speed cassette (specifically Shimano 105 "road" components). You can't use a wider wheel and you don't want to use spacers.

The stock Axis 2.0 wheels are a little bit heavy but they're not particularly slow or uncomfortable. In those regards you'll get much more reward from changing your tyres and/or pressures. And tyres are a lot less expensive than wheels.

Go light. Go Carbon.

Thanks! I get it now. Front is standard 100mm and rear is standard 135mm, so any wheel with axles over that will not fit regardless of spaces and what not. Well, that sucks.

I really didn't want to spend that much on a set of wheels, but I figured if I'm going to upgrade I might as well get something better than spending less and get something that is more or less the same.

Whether is actually going to be worth it... we'll see.

Okay, so let me make it clear that I know very, very little about bikes. But I understand a bit about physics and I really think that if you're "mostly interested in performance, comfort and a general feeling of improvement over the Axis 2.0." then you should not replace your wheels unless you've already tried many tyre and pressure combos.

I'm afraid you're simply not going to get what you want simply by changing wheels. Find the correct tyres and pressures for you to be comfortable and confident with the handling and then consider changing the wheelset for incremental improvements in performance.

Save yourself 100's in the process. :thumb:

+1. I would definitely look into nicer tires. Otherwise the wheelset isn't going to make a whole lot of difference for most people.

Any experience with them and their quality?

Is it for most people who have never tried better wheels or is it for people who have tried better wheels?

from all the reviews I've been reading in the last few days about various wheel sets, most of the people seem to suggest the better set is a noticeable difference.

ive gotten better wheelsets for two different hybrids. much lighter than stock wheels. i can see how acceleration may be better but in the end my performance for my rides were not appreciably better. it might be worth it on an expensive road bike but for a hybrid? Even a nicer flat bar roadbike, the difference is small.

My road bike's stock wheels were 2000 grams for the pair. (Not including the cassette cogs, tires, tubes, or quick release, of course). After 15,000 miles (25,000 km), some of the rim spoke holes developed stress cracks, and one spoke nipple pulled partway through the rim. So I got a nice pair of replacement wheels.

The new wheels were 1550 grams, 450 grams or 1 pound lighter. The difference was subtle, with the most noticeable change showing as faster steering response on sharp handlebar movements. I suppose the acceleration was a little quicker, but not obvious. The new wheels "seemed" faster, but of course, I never did a double blind test.

So: the wheels were nice, but not a huge change.

Tires!
What tires do you have now, and what size?
What do you weigh, and how much air pressure are you using?

The more expensive road tires have thin, flexible sidewalls, and grippy rubber compounds. When the tires are at the appropriate pressure for the rider's weight, they flex over rough road surfaces instead of vibrating or bouncing the bike and rider. And the handling on turns is much better, both from grippy rubber and less bouncing on rough spots. Really, the difference is huge--this is by far the most effective upgrade.

So far, on the thread comments:
3 votes for good tires.
1 vote for no-name carbon rim wheels. On a hybrid. (Those wheels don't look bad for a racing bike. But they are 1/3 or 1/4 the price of name brand carbon wheels, so there's some risk of possible quality problems. )

Many of my friends run them on their mountain bikes. No issues at all.

The tires are the stock Espoir Sport (30x700)

I weigh about 70 Kg, and I keep the pressure to almost the max of what it says on the tyre, which is [85-95 PSI].

I think part of the upgrade is because I feel this bike deserve better wheels, and part is I feel the upgrade will improve the ride.

Also, I like the fact that the wheels cost more than a lot of the bikes I see around...:lol:

Marginal gains. The concept employed by the SKY racing team. It worked for them. If all your upgrades add up to a better, more valued experience then it is worth it.

Same bike, same tyres, same weight - try 60-70 PSI and you can go even lower on the front if you like. Free to try, do report back.

Your bike costs more than a lot of the bikes you'll see, screw the wheels!

Thanks for that. I tried it the other day and it felt a smoother more comfortable ride. Today I pumped it back to 90s and it seemed slightly less comfortable. However, it also seemed to be rolling better. I did clean and re-lube the chain so that might be a factor, I don't know. I think 80 PSI might be the best compromise.
