Hi there.

I have just got a momsen al529 R-type from a mate of mine, he hasn’t ridden the bike in ages so there’s a bit of servicing to do, however sadly we had to cut the tires off as the sealing had gone all funny.

Do you guys know is 29x 2.10 tire would fit on this bike ?

2.1 is very skinny by today’s standards and will definitely fit.

 

Do you perhaps know what the year model is?

 

Things to look at servicing first would be suspension and bleed the brakes.

 

Then check all the bearings and pivots where needed.

 

Then check the drivetrain for chain stretch and overall condition of the cassette and chainring. Replace the cables and housings while you’re at it.

The bike is the 2012 Model but most of the things on the bike have been upgraded so it’s not like it came.

Yes the brakes are way to spongy will definitely need to bleed, was thing about doing it myself apparently it’s not that hard to do ?? Or is it better to take it to the bike shop and let them bleed it ?

Where are you located?

 

It's a hardtail so you can easily service eveything yourself besides the fork and bleeding brakes. I would personally take it in to have that done. Might also need new rotors and pads for the brakes.

 

They can quickly check chain wear, chainring and cassette wear.

 

2.1 tyres will work but are skinny. I'd recommend 2.2 on that bike as it is an XC bike. Also, you can buy rim tape, sealant and valves and easily do a fresh tubeless conversion yourself. Just remove old tape, clean the rims thoroughly with a cloth a rubbing or surgical alcohol then start the conversion.

I’m in Durban.

Yeah most of the stuff I already sorted out today, chain and gears are all hundreds and shifters are shifting properly.

The brakes need to be serviced but the rotors and brake pads are still perfect.

I just need tyres and new grips and she’ll be ready for the first ride soon.

The only thing is I’m a student and doing a few jobs in December and getting paid after Christmas so I can’t spend too much on tires now and there’s a decent second hand set of 29x2.10 that I’ve found, so for now they’ll have to do.

The rims are tubeless ready but they just needed a good clean today.

I have a AL129..Just check how far apart your chain stays are going towards the crank area....Although I could run a 2.2 tyre on the back there is minimal clearance so I use a 2.1....Using a 2.2 in summer just caused clogging with mud  at the back...
Momsen could have given a little bit more clearance on this frame....
If you are not a DIY sort of person and dont plan on starting then let the bike shop do the brakes...that mineral oil is expensive...

That’s a Maxxis 29X2.20 on the back of my sons 529 16” frame. [emoji1303]

 

And on a 30mm internal width Rapide Rim.

2.1 Tyres are fine. Using it currently on my AL329.

2.2 Tyres are better, but like you had to use what was available.

One of the things I want to upgrade this year.

So you reckon a 2.25 should fit as I have also found a nice set of 29x2.25?

Should be an easy fit. I recon close to 10mm gap (finger wide) each side of dropout and chainstay on above picture from me. Frame is very accommodating.

Thanks so much, the tires should arrive sometimes this week so 29x2.25 it is.

So hopefully all goes well.

Thanks for the advice
