Arisun Mount Baldy Tyre Review 26 x 2.50

Arisun Mount Baldy Tyre Review 26 x 2.50 - Intro


Just £23 for a pair of these Arisun Mount Baldy Tyre Review 26 x 2.50 tyres on Ebay at the moment, and as such I have pruchased these with an aim to building up an off road / MTB type bike. I haven't owned a pair of mount bike tyres for years.



You can see they tyres on a new build. In the above video. Below shows picture of initial build. 



Arisun Mount Baldy Tyre Review 26 x 2.50 - First Impressions

These are folding tyres, and come zip tied to a plastic hanger. The rubber has a supple feel to to it and the tyres unfold nicly. Mounting them on the rims (EX325) was easy, and the nbeads seated well. I used innertubes when insttaling these Mopunt Baldy tyres from Arisun. The knobs are small, and although I havn't ridden on these yet they should roll quiote well.



Arisun Mount Baldy Tyre Review 26 x 2.50 - Width

These Mount Baldy Tyres are lablled as 2.5" but this is misleading, they are 2.35". LAbelled at 559-60 size in ETRO sizing this 60mm width is accurate, but a imperial conversion of 60mm is 2.35" not 2.5" so this is misleading.

Arisun Mount Baldy Tyre Review 26 x 2.50 - Conclusions

I will update this post when I have finished the bike and gone for a ride. The tyres certainly seam fair quality, and for the price I paid are unlikely to disappoint. The mount well, have a quality finish, and are not excessively knobbly.

Schwalbe AV13 AV13F and AV13D Comparison

Schwalbe AV13 AV13F and AV13D Comparison - Intro


First off, this comaprsion would apply also to SV13,  SV13F and SV13D. The AV and SV at the front of each inner tube type denotes the type of valve. AV is schrauder, the SV is presta.

But why write a comparison . . .we hopefully it will save you some time:

AV13 AV13F AV13D
 General Description












 This is a normal width tube for use in normal size tires. 1.5 to 2.5", although better used for tires up to 2"  This is a wider tube (but not a lot wider) that weigh the same as a normal tube, so is a bit thinner.  This is the same thickness as a normal AV13 tube and a bit wider. But again not much wider.
 Weight

190g  185g  290g
 Price

 £4  £8  £6
Schwalbe Blurb













A standard Schwalbe tube holds the air considerably longer. Due to the purity of the rubber compound. Due to the uniform wall thickness.  Large volume. Low Weight.  Extremely robust. A reinforced rubber base protects against dreaded valve shearing off. Only in Downhill sizes. If you want large volume with low weight, choose Extralight
Thorpy's Rating 5/5 4/5 5/5








Below I have includedsome pictures of the tubes laid out next to one another. From left to right, AV13, AV13F and AV13D. As you can see there is not a great deal of width differnce between them.




Schwalbe AV13 AV13F and AV13D Comparison - Conclusions 


Whilst the Standard Tube (AV13) is very good quality and will fit nealry all tires sizes, the AV13 costs considerbaly more and offers little in teh way of befits other then the slightly wider size it can be inflated too. The AV13F is also the most expensive of all three tubes.

The AV13D is worth using if you have a wider tire. But the Michelin C6 is in by opion a better tube, as it is wider out of the box, and requires less streching to get up to size.
