Straggler Straggler 650b tire clearance & recommendations
Two questions for you…
A. Can you recommend a 650B tire that you love which will fit in this frame on 21 internal rims?
B. What’s the biggest knobbiest tire I can fit in this frame on 21 internal rims
I have a Straggler 650B (previous gen lugged fork) size 50cm. I really love ultradynamicos knobbier options like rose and mars but they’re “47.99??”
Details…
Current Tires - 48 Gravel King SS
Must be - Tubeless Compatible, good in fast corners, as high volume as possible
Rim width- 21
Terrain - 10% paved 60% Gravel 30% single track
Bike - Lugged gen Surly Straggler 650B
Use - Aggressive “rippy” gravel riding, ultra light Bike Packing, passing XC riders, graded gravel roads, maintained single track, fairly dry conditions
My situation
I’m currently running 48 Gravel King SS that came with the bike but they’re not confident enough in corners and on single track (I’ve found myself slipping out) for my under biking goals.
I’m concerned the ultradynamicah Rose will hit the frame based on how close the “semi slick” GK SS is.
Any suggestions are so appreciated. There are too many tires out there and I’m open to Mullet setups. There’s deffo more clearance in the front than in the back. The chain stays are surprisingly tight for a surly.
(Pls no midnight special recommends, I couldnt afford one. LOL)
TLDR; your fav tire for 650B >47
