  • The answer is usually just ‘overshoes’ though isn’t it?

  • Gravel anti?

  • Nice for a Ribble

  • Any recommendations for a fork for the Spesh Sequoia with large tyre clearance for 29er wheels?

    I have the opportunity to get a Sequoia frame for cheap, and have a two wheelsets for my 29er mtb so am tempted by the idea to have two bikes I could swap the wheels between for different styles of bikepacking trips (one wheel has dynamo hub).

    In an ideal world, it could take 29x2.4" tyres, 15mm Thru axle, 1 1/2" - 1 1/8" steerer, low rider rack mounts, and be carbon. I realise that's probably asking too much though.

  • You'll ruin the geometry of your sequoia if you use a fork for 2.4" tyres.

  • By going from a factory 45mm (with at least 6mm clearance for ISO4210) to a 61mm tyre? Ruin?

  • Yes, your tyre is on 2 sides of your wheel. So it lifts the front 32mm, which is a lot!

    Also forks with that much clearance have a significant larger axle to crown length thus lifting your headtube even further.

  • Because of the offset to compensate for the lack of suspension?

  • Ok, thanks for your advice.

    I do disagree a bit though, the axle is only lifted 16mm (one side of the tyre between axle and ground), the same happens to the rear so angles stay the same but BB, standover and CoG height are increased by 16mm.

    Then the A to C will be slightly larger, about 16mm assuming clearance is kept the same, pushing the headtube up a bit and making the head angle marginally slacker.

  • 8mm no?

    ... assuming quite a round tyre profile.

  • No idea where 52mm comes from.

  • Because of the offset to compensate for the lack of suspension?

    Not necessarily. But just making room for the a wheel and tyre that much bigger requires more A to C distance.

  • You are right, my bad. Edited my earlier post.

    No way a 29er 2.4" will fit in the back.

    Good luck finding a 411mm AC fork, I couldn't find one.

  • Sell Sequoia and get an AWOL.

  • The problem is you'll need to move your saddle further forward, a longer stem, wider bar for the much slower handling on the road (probably OK off road), and drop bar with near MTB front end is not as easy to ride as a traditional flat bar.

    TL:DR; get a AWOL.

  • If you really want big tyres, get a 650b wheelset and 2.1 tyres instead which will fit, also this allow it to handle equally well as a 700c with 42mm tyres and also kept the weight down.

  • I couldn't get more than 2.2" in my AWOL.

  • Hah, in that case, stick to Sequoia and put 2.1 tyres, it's still a massive tyres regardless.

  • Wow, that fork takes 2.1"? Quite amazed by that.

  • But to be quite honest, if you want 2.4 tyres, then maybe a rigid MTB would be a much better choice, or those bike like the Genesis Vagabond.
